TypeConsumer sound cards

Sound Blaster is a family of sound cards and audio peripherals designed by Creative Technology/Creative Labs of Singapore. The first Sound Blaster card was introduced in 1989.

Sound Blaster sound cards were the de facto standard for consumer audio on the IBM PC compatible platform until the widespread transition to Microsoft Windows 95 and the integration of commoditized audio electronics in PCs. Windows 95 standardized the programming interface at the application level and thereby eliminated the importance of backward compatibility with Sound Blaster cards.

By 1995, Sound Blaster cards had sold over 15 million units worldwide and accounted for seven out of ten sound card sales.[1] To date, Sound Blaster has sold over 400 million units,[2] and their current product lineup includes USB-powered DACs as well as other audio adapters.[3]

Creative Music System and Game Blaster

[edit]

Creative Music System

[edit]
Creative Music System sound card

The history of Creative sound cards started with the release of the Creative Music System ("C/MS") CT-1300 board in August 1987. It contained two Philips SAA1099 integrated circuits, which, together, provided 12 channels of square-wave "bee-in-a-box" stereo sound, four channels of which can be used for noise.

These ICs were featured earlier in various popular electronics magazines around the world. For many years Creative tended to use off-the-shelf components and manufacturers' reference designs for their early products. The various integrated circuits had white or black paper stickers fully covering their tops to hide their identities. On the C/MS board in particular, the Philips chips had white pieces of paper with a fictitious "CMS-301" inscription on them. Real Creative parts usually had consistent CT number references.

Surprisingly, the board also contained a large 40-pin DIP integrated circuit bearing a "CT 1302A CTPL 8708" (Creative Technology Programmable Logic) serigraphed inscription and looking exactly like the DSP of the later Sound Blaster. Software, including Creative's own, use this chip to automatically detect the card (by trying certain register reads and writes).

Game Blaster

[edit]

A year later, in 1988, Creative marketed the C/MS via Radio Shack under the name Game Blaster. This card was identical in every way to the precursor C/MS hardware. Whereas the C/MS package came with five floppy disks full of utilities and song files, Creative supplied only a single floppy with the basic utilities and game patches to allow Sierra Online's games using the Sierra Creative Interpreter engine to play music with the card and it also included a later revision of the game Silpheed that added C/MS support.

First generation Sound Blasters, 8-bit ISA & MCA cards

[edit]

Sound Blaster 1.0, CT1310, CT1320A, CT1320B

[edit]
Sound Blaster 1.0 (CT1320B); C/MS chips in sockets (labeled U14, U15) are seen.

The Sound Blaster 1.0 (code named "Killer Kard"),[4] CT1320A, was released in 1989. In addition to Game Blaster features, it has a 9-voice (11 voices in drum mode)[5] FM synthesizer using the Yamaha YM3812 chip, also known as OPL2. It provided compatibility with the market leader AdLib sound card, which had gained support in PC games in the preceding year. Creative used the "DSP" acronym to designate the digital audio part of the Sound Blaster. This stood for Digital Sound Processor, rather than the more common digital signal processor, and is a simple microcontroller from the Intel MCS-51 family (supplied by Intel and Matra MHS, among others). It can play back 8-bit monaural sampled sound at up to 23 kHz sampling frequency and record 8-bit at up to 12 kHz. The sole DSP-like features of the circuit are ADPCM decompression and a primitive non-MPU-401-compatible MIDI interface. The ADPCM decompression schemes supported are 2 to 1, 3 to 1 and 4 to 1. The CT1320B variety of the Sound Blaster 1.0 typically has C/MS chips installed in sockets rather than soldered on the PCB, though units do exist with the C/MS chips soldered on.[6]

Some sources note that the original Sound Blaster 1.0 was produced under the CT1310 number. This however is a topic of ongoing debate. Creative refers to CT1310 for the Sound Blaster 1.0 on its website.[7][8][9]

In less than a year, the Sound Blaster became the top-selling expansion card for the PC. It achieved this by providing an AdLib-compatible product, with additional features, for the same, and often lower, price. The inclusion of a game port was important to its early success. PCs of this era did not include a game port. Game port cards were costly (around US$50) and used one of the few expansion slots PCs had at the time. Given the choice between an AdLib card or a fully-compatible Sound Blaster card that came with a game port, saved a slot, and included the "DSP" for not much more in price, many consumers opted for the Sound Blaster. In-game support for the digital portion of the card did not happen until after the Sound Blaster had gained dominance.

When Microsoft announced Multimedia PC (MPC) in November 1990, it suggested to developers that they use the Sound Blaster as it was the only sound card that came close to complying with the MPC standard. The press speculated that Microsoft based the MPC standard on the Sound Blaster's specifications.[10] By 1993 Computer Gaming World wondered "why would a gamer" buy a competing AdLib card that was not Sound Blaster-compatible.[11] Creative advertised the Sound Blaster 16 ("the 16-bit sound standard") with the slogan "Get Real", emphasizing its "real 100% Sound Blaster compatibility" and rhetorically asking "why those other manufacturers spend so much time comparing themselves to Sound Blaster".[12]

Reception

[edit]

Compute! in 1989 stated that with Sound Blaster, "IBM-compatible computers have taken the lead in sound and music for personal computers". Naming it a Compute! Choice, the magazine described the quality of the opening music of Space Quest III with the card as "extraordinary", praising the quality compared to the Roland MT-32 and Ad Lib versions. Compute! approved of the card's DMA and Creative's dissemination of technical information, and concluded that while the more-expensive MT-32 was superior, Sound Blaster's audio quality was better than that of Ad Lib or Game Blaster.[13]

Sound Blaster 1.5, CT1320C, CT1320U

[edit]
Sound Blaster 1.5 (CT1320C); C/MS chip sockets (labeled U14, U15) seem empty.

Released in 1990, the Sound Blaster 1.5, CT1320C, dropped the C/MS chips, which were no longer popular with game developers. Instead, the board had two empty sockets, which could be user upgraded by purchasing the C/MS chips directly from Creative or Phillips SAA-1099s from another source. Otherwise the card functions identically to the Sound Blaster 1.0.[14] The CT1320U variety has the same layout as the CT1320C.[15]

Sound Blaster 2.0, CT1350

[edit]
Sound Blaster 2.0 (CT1350B), without C/MS and FM chipset

The final revision of the original Sound Blaster, the Sound Blaster 2.0 was released in October 1991,[16] CT1350, added support for "auto-init" DMA, which assisted in producing a continuous loop of double-buffered sound output. Similar to version 1.0 and 1.5, it used a 1-channel 8-bit DAC. However, the maximum sampling rate was increased to 44 kHz for playback, and 15 kHz for record. The DSP's MIDI UART was upgraded to full-duplex and offered time stamping features, but was not yet compatible with the MPU-401 interface used by professional MIDI equipment. The Sound Blaster 2.0's PCB-layout used more highly integrated components, both shrinking the board's size and reducing manufacturing cost.

Owners of previous revision Sound Blaster boards could upgrade their board by purchasing the V2.00 DSP chip from Creative Labs, and swapping the older DSP V1.0x with the newer replacement. The upgraded board gained the auto-init DMA and new MIDI capabilities of the Sound Blaster 2.0 but not the expanded sampling rates. The upgrade was necessary for full compatibility with the Windows 3.0 Multimedia Extensions upgrade.

Sound Blaster MCV, CT5320

[edit]
The Sound Blaster MCV (CT5320B); note that the card has a greater width and thus lacks the typical MCA sled.

Sound Blaster MCV, CT5320, was a version created for IBM PS/2 Model 50 and higher and their ISA-incompatible Micro Channel architecture. The MCV Sound Blaster has some issues outputting audio while running on PS/2s with CPUs running faster than 16 MHz. However, the joystick interface is still inoperable on PS/2s it was designed for due to the slow-speed Schottky chips that have been installed. None of these timing issues affect the Yamaha YM3812. Some of the MCV Sound Blasters were released with faster Schottkys which eradicated some of the problems.[17]

Second-generation Sound Blasters, 16-bit ISA & MCA cards

[edit]

Sound Blaster Pro, CT1330

[edit]
Sound Blaster Pro (CT1330A) rev.4

Model CT1330, announced in May 1991, was the first significant redesign of the card's core features, and complied with the Microsoft MPC standard.[10]. The Sound Blaster Pro supported faster digital input and output sampling rates (up to 22.05 kHz stereo or 44.1 kHz mono), added a "mixer" to provide a crude master volume control (independent of the volume of sound sources feeding the mixer), and a crude high pass or low pass filter. The Sound Blaster Pro used a pair of YM3812 chips to provide stereo music-synthesis (one for each channel). The Sound Blaster Pro was fully backward compatible with the original Sound Blaster line, and by extension, the AdLib sound card. The Sound Blaster Pro was the first Creative sound card to have a built-in CD-ROM interface. Most Sound Blaster Pro cards featured a proprietary interface for a Panasonic (Matsushita MKE) drive. The Sound Blaster Pro cards are basically 8-bit ISA cards, they use only the lower 8 data bits of the ISA bus. While at first glance it appears to be a 16-bit ISA card, it does not have 'fingers' for data transfer on the higher "AT" portion of the bus connector. It uses the 16-bit extension to the ISA bus to provide the user with an additional choice for an IRQ (10) and DMA (0)m channel only found on the 16-bit portion of the edge connector.

A short lived joint developed project between Creative and Tandy resulted in the Creative/Tandy Multimedia Sound Adapter, 849–3030. This Sound Blaster Pro derived card was factory installed in Tandy Multimedia PCs. It combined the CT1330 with Tandy joystick and MIDI ports (not MPU-401 compatible).[18]

Sound Blaster Pro 2, CT1600

[edit]
Sound Blaster Pro 2 (CT1600)

The revised version, the Sound Blaster Pro 2, CT1600, replaced the YM3812s with a more advanced Yamaha YMF262 (OPL3). Otherwise it is functionally identical to the original Sound Blaster Pro. Shortly after the release of the Sound Blaster Pro 2 version, Creative discontinued the original Sound Blaster Pro.

The Sound Blaster Pro 2 was also sold with the following on-board CD-ROM controllers:

  • Sound Blaster Pro 2, SCSI, CT1610
  • Sound Blaster Pro 2, LMSI, CT1620
  • Sound Blaster Pro 2, Sony, CT1690
  • Sound Blaster Pro 2, Mitsumi, CT2600

Packaged Sound Blaster cards were initially marketed and sold into the retail-channel. Creative's domination of the PC audio card business soon had them selling the Sound Blaster Pro 2 OEM, CT1680, to customers for integration into pre-assembled PCs.

Creative also sold Multimedia Upgrade Kits containing the Sound Blaster Pro. The kit bundled the sound card, a Matsushita CD-ROM drive (model 531 for single-speed, or 562/3 for the later double-speed (2x) drives), and several CD-ROMs of multimedia software titles. As CD-ROM technology was new, the kit included CD-ROM software, representing a very good value to customers. One such kit, named "OmniCD", included the 2x Matsushita drive along with an ISA controller card and software, including Software Toolworks Encyclopedia and Aldus PhotoStyler SE. It was compliant with the MPC Level 2 standard.

Sound Blaster Pro 2 MCV, CT5330

[edit]

The Sound Blaster Pro 2 MCV, CT5330, was a version created for IBM PS/2 model 50 and higher and their MicroChannel bus.


Third generation Sound Blasters, 16-bit ISA cards

[edit]

Sound Blaster 16

[edit]
Sound Blaster 16 (CT2940)

The next model, the Sound Blaster 16, announced in June 1992, introduced:

Eventually this design proved so popular that Creative made a PCI version of this card. Creative's audio revenue grew from $40 million per year to nearly $1 billion following the launch of the Sound Blaster 16 and related products. Rich Sorkin was General Manager of the global business during this time, responsible for product planning, product management, marketing and OEM sales. Moving the card off the ISA bus, which was already approaching obsolescence, meant that no line for host-controlled ISA DMA was available, because the PCI slot offers no such line. Instead, the card used PCI bus mastering to transfer data from the main memory to the D/A converters. Since existing DOS programs expected to be able to initiate host-controlled ISA DMA for producing sound, backward compatibility with the older Sound Blaster cards for DOS programs required a software driver work-around; since this work-around necessarily depended on the virtual 8086 mode of the PC's CPU in order to catch and reroute accesses from the ISA DMA controller to the card itself, it failed for a number of DOS games that either were not fully compatible with this CPU mode or needed so much free conventional memory that they could not be loaded with the driver occupying part of this memory. In Microsoft Windows, there was no problem, as Creative's Windows driver software could handle both ISA and PCI cards correctly.

Sound Blaster ViBRA16

[edit]
Vibra based card with FM radio: SoundForte RadioPlus SF16-FMP2 by MediaForte

The Sound Blaster ViBRA16 was an inexpensive single-chip implementation of the Sound Blaster 16 for the OEM market. Creative Labs also used this chip for the Sound Blaster 32, Phone Blaster and Phone Blaster 28.8 (VIBRA plus modem, CT3120 and CT3220.) and many other value-edition cards. External Yamaha OPL3 FM music synthesis was retained in earlier boards built around the ViBRA16 or ViBRA16s controllers, whilst the later (and more common) ViBRA16 boards used CQM (Creative Quadratic Modulation) developed by E-mu Systems. This series included the ViBRA16 (CT2501), ViBRA16s (CT2502, CT2504), ViBRA16c (CT2505) PnP and ViBRA16XV (CT2511) chips. The primary advantage of the ViBRA16 was the inclusion of a 14.4 kbit/s telephony Modem; it also functioned as a telephone.

Fourth generation Sound Blasters, 16-bit ISA cards, dynamic sample-based synthesis

[edit]

Sound Blaster AWE32

[edit]
Sound Blaster AWE32 (CT3990)

Released in March 1994, the Sound Blaster AWE32 (Advanced WavEffects) introduced an all new MIDI synthesizer section based on the EMU8000. The AWE32 consisted of two distinct audio sections; the Creative digital audio section (audio codec, optional CSP/ASP chip socket, Yamaha OPL3), and the E-mu MIDI synthesizer section. The synthesizer section consisted of the EMU8000 sampler and effects processor, an EMU8011 1 MB sample ROM, and 512 KB of sample RAM (expandable to 28 MB). To fit the new hardware, the AWE32 was a full-length ISA card, measuring 14 in (360 mm).

Sound Blaster 32

[edit]
Sound Blaster 32 ISA (CT3930)

A derivative of the AWE32 design, the Sound Blaster 32 (SB32) was a value-oriented offering from Creative. Announced on June 6, 1995, the SB32 became the new entry-level card in the AWE32 product-line (previously held by the AWE32 Value.) The SB32 retained the AWE32's EMU8000/EMU8011 MIDI-synthesis engine and built-in instrument ROM, but dropped the onboard RAM, the Wave Blaster header, and the CSP port. The SB32 used the Vibra chip to reduce component count, which meant bass/treble/gain control was limited compared to the AWE32. The loss of onboard RAM is offset by the inclusion of 30-pin SIMM RAM sockets, which allow up to 28 MB RAM to be installed and used by the EMU engine.

Sound Blaster AWE64

[edit]
Sound Blaster AWE64 Gold (CT4390)

The AWE32's successor, the Sound Blaster AWE64 (November 1996), was significantly smaller, being a "half-length ISA card" (that term is misleading—see the pictures for size comparison). It offered similar features to the AWE32, but also had a few notable improvements, including support for greater polyphony, although this was a product of 32 extra software-emulated channels (the additional channels could also be obtained on AWE32 hardware by using the AWE64's driver software). The 30-pin SIMM slots from AWE32/SB32 were replaced with a proprietary memory format which could be (expensively) purchased from Creative.

The main improvements were better compatibility with older SB models, and an improved signal-to-noise ratio. The AWE64 came in two versions: A standard version (later rebranded as Value) with 512 KB of RAM and a Gold version with 4 MB of RAM and a separate S/PDIF output.

Fifth generation Sound Blasters, PCI cards, multi-channel and F/X

[edit]

Ensoniq AudioPCI-based cards

[edit]
Ensoniq AudioPCI

In 1998, Creative acquired Ensoniq Corporation, manufacturer of the AudioPCI, a card popular with OEMs at the time. It was a full-featured solution with wavetable MIDI (sample-based synthesizer), 4-speaker DirectSound3D surround sound, A3D emulation, and DOS legacy support via a terminate-and-stay-resident program. It was cheap due to lack of hardware acceleration. It is full-duplex but at least in MS Windows it cannot play back several sources at once.

Creative released many cards using the original AudioPCI chip, Ensoniq ES1370, and several boards using revised versions of this chip (ES1371 and ES1373), and some with Creative-labeled AudioPCI chips. Boards using AudioPCI tech are usually easily identifiable by the board design and the chip size because they all look quite similar. Such boards include Sound Blaster PCI64 (April 1998), PCI128 (July 1998), Creative Ensoniq AudioPCI, Vibra PCI and Sound Blaster 16 PCI.

An ES137x chip contains three stereo sample rate converters, some buffers and a PCI busmaster interface. Analogue interfacing is done by a codec chip, which runs at a fixed sampling frequency of 44 (Ensoniq Audio PCI) or 48 kHz (Creative's versions). (ISA soundcards had not resampled but switched between different time bases.) ES137x do not support SoundFonts but a filter-less MIDI engine with wavetable (sample table) sets of 2, 4, and 8 MB size.

Sound Blaster Live!

[edit]
Sound Blaster Live! (CT4830)

When the Sound Blaster Live! was introduced in August 1998, the use of a programmable digital signal processor in PC-audio was not unprecedented, as IBM had already done that with cheap Mwave sound- and modem-cards and Turtle Beach with their professional Hurricane soundcards.

The Live! was built around Creative's new EMU10K1 chip, which contained 2.44 million transistors and was advertised of processing a flashy 1,000 MIPS. The EMU10K1 (and its successors) did not use on-card RAM/ROM storage for instrument samples, instead it used a PCI busmaster interface to access sample-data stored in the host-PC's system memory. A/D- and D/A- converters as well as analogue mixing is done by an AC'97 chip running at 48 kHz sampling rate. All members of the SB Live! family have at least four-channel analog audio outputs and a 15-pin MIDI/Joystick multiport.

For game titles, EAX 1.0 (and later 2.0) (environmental audio extensions, which briefly competed with the now defunct A3D 2.0) added hardware-accelerated acoustic effects. The EMU10K1 provided high-quality 64-voice sample-based synthesizer (marketed as "Wavetable"), with self-produced or third-party customized patches or "Soundfonts", and the ability to resample the audio output as input and apply a range of real-time DSP effects to any set of audio subchannels present in the device.

The first model and flagship of the SB/Live family was the SB Live! Gold. Featuring gold tracings on all major analog traces and external sockets, an EMI-suppressing printed circuit board substrate and lacquer, the Gold came standard with a daughterboard that implemented a separate 4-channel alternative mini-DIN digital output to Creative-branded internal-DAC speaker sets, a S/P-DIF digital audio Input and Output with separate software mappings, and a fully decoded MIDI interface with separate Input and Output (along with on mini-DIN converter.) The Gold highlighted many features aimed at music composition; ease-of-use (plug-and-play for musicians), real-time loopback-recording of the MIDI-synthesizer (with full freedom of Soundfonts, and environmental effects such as reverb, etc.), and bundled MIDI-software.

The mainstream model was the Sound Blaster Live! Like the Gold, the Live featured multi-speaker analog output (up to four channels), and identical music/sound generation capabilities (without the bundled MIDI software and interfacing-equipment.)

Later versions of the Live!, usually called Live! 5.1, offered 5.1-channel support which adds a center channel speaker and LFE subwoofer output, most useful for movie watching. The Live! 5.1 could also use one of the 3.5 mm jack ports as an SPDIF out, which allowed the connection of an external decoder.

Creative also released a Sound Blaster Live! Player 1024 edition, which is identical to the regular Sound Blaster Live!, but with the addition of some extra software.

Sound Blaster PCI 512

[edit]

The Sound Blaster PCI 512 (CT4790) is an EMU10K1-based sound card designed to fill a lower cost segment than the Live! Value. It is capable of most of the Live! Value's features aside from being limited to 512 MIDI voice polyphony (a software-based limitation), lacking digital I/O, removal of expansion headers, and only stereo or quadraphonic output support. The card's circuit layout is somewhat simpler than that of the Live! series.[19][20]

Sound Blaster Audigy

[edit]
Sound Blaster Audigy Player

The Sound Blaster Audigy (August 2001) featured the Audigy processor (EMU10K2), an improved version of the EMU10K1 processor that shipped with the Sound Blaster Live!. The Audigy could process up to four EAX environments simultaneously with its upgraded on-chip DSP and native EAX 3.0 ADVANCED HD support, and supported up to 5.1-channel output.

The Audigy was controversially advertised as a 24-bit sound card. The EMU10K2's audio transport (DMA engine) was fixed at 16-bit sample precision at 48 kHz (like the EMU10K1 in the original Live!), and all audio had to be resampled to 48 kHz in order to be accepted by the DSP (for recording or rendering to output.)

Sound Blaster Audigy 2 (September 2002) featured an updated EMU10K2 processor, sometimes referred to as EMU10K2.5, with an improved DMA engine capable of 24-bit precision. Up to 192 kHz was supported for stereo playback/record, while 6.1 was capped at 96 kHz. In addition, Audigy 2 supported up to 6.1 (later 7.1) speakers and had improved signal-to-noise ratio (SNR) over the Audigy (106 vs. 100 decibels (A)). It also featured built-in Dolby Digital EX 6.1 and 7.1 decoding for improved DVD play-back. The Audigy 2 line were the first sound cards to receive THX certification.

Sound Blaster Audigy 2 ZS (September 2003) is essentially an Audigy 2 with updated DAC and op-amps. Audigy 2 ZS uses the Cirrus Logic CS4382 DAC together with the op-amps and can produce an output SNR of 108 dB. There were a few slight printed circuit board modifications and 7.1 audio support was added.

Sound Blaster Audigy 4 Pro (November 2004)[21] was an Audigy 2 ZS with updated DACs and ADCs, the new DAC being the Cirrus Logic CS4398, boosting the output SNR to 113 dB. Other than a breakout box, it has no distinguishable difference from the Audigy 2 ZS. The DSP is identical to the Audigy 2 ZS's but Creative put an "Audigy 4" sticker to cover the chip, making it appear as if it is a new chip. The Audigy 4 Pro is not to be confused with the Audigy 4 (Value) which contains lower quality DACs and does not have golden plated jacks. The Audigy 4 (Value) is more in line with the Audigy 2 Value series. The Audigy 4 had a shorter life span than its predecessors, due to the short window between it and the next-generation Sound Blaster X-Fi.

Sound Blaster Audigy Rx (September 2013) is similar to the Audigy 4 but with a dedicated 600-ohm headphone amplifier and a PCIe 1x interface.[22]

Sound Blaster Audigy Fx (September 2013) also features a 600-ohm amplifier and a PCIe interface, but lacks the EMU10K DSP.[23]

Sound Blaster X-Fi

[edit]
Sound Blaster X-Fi XtremeGamer Fatal1ty Pro

The X-Fi (for "Extreme Fidelity") was released in August 2005 and as of 2012 came in XtremeGamer, Titanium, Titanium Fatal1ty Professional, Titanium Fatal1ty Champion and Elite Pro configurations. The 130 nm EMU20K1 (or EMU20K2 for Titanium series models) audio chip operates at 400 MHz and has 51 million transistors. The computational power of this processor, i.e. its performance, is estimated as 10,000 MIPS, which is about 24 times higher than the estimated performance of its predecessor, the Audigy processor. Beginning with the 2008 Titanium models, newer X-Fi cards switched from PCI to PCI Express x1 connectors. With the X-Fi's "Active Modal Architecture" (AMA), the user can choose one of three optimization modes: Gaming, Entertainment, and Creation; each enabling a combination of the features of the chipset. The X-Fi uses EAX 5.0 which supports up to 128 3D-positioned voices with up to four effects applied to each. This release also included the 24-bit crystallizer, which is intended to pronounce percussion elements by placing some emphasis on low and high pitched parts of the sound. The X-Fi, at its release, offered some of the most powerful mixing capabilities available, making it a powerful entry-level card for home musicians. The other big improvement in the X-Fi over the previous Audigy designs was the complete overhaul of the resampling engine on the card. The previous Audigy cards had their DSPs locked at 48/16, meaning any content that did not match was resampled on the card in hardware; which was done poorly and resulted in a lot of intermodulation distortion. Many hardcore users worked around this by means of resampling their content using high quality software decoders, usually in the form of a plugin in their media player. Creative completely re-wrote the resampling method used on the X-Fi and dedicated more than half of the power of the DSP to the process; resulting in a very clean resample.[citation needed]

Sixth generation Sound Blaster Sound Core3D cards

[edit]

Sound Blaster Recon3D

[edit]
Sound Blaster Recon3D

The Recon3D series was announced in September 2011 and includes the Recon3D PCIe, Recon3D Fatal1ty Professional and Recon3D Fatal1ty Champion. The cards use the new integrated Sound Core3D chip, which features the Quartet DSP from the X-Fi series as well as integrated DAC, ADC and I/O interface in a 56-pin package.[24] The Asia-only Recon3D Professional Audio is basically a Recon3D PCIe with some extra accessories such as cables.[25]

The Recon3D series of sound cards do not support ASIO.[26]

The Recon3D comes with a bundled software called the SBX Pro Studio. SBX Pro Studio allows users to adjust the amount of virtual Surround, Crystallizer, Bass, Smart Volume and Dialog Plus for their Recon3D sound cards.[27] The Recon3D also has got the Crystal Voice feature that reduces the pickup of background noises like the hairdryer or vacuum cleaner when a beamforming microphone is used.[28]

Reviews have been generally positive, but pricing and small model differences have raised questions. Especially the low and mid priced models Recon3D PCIe and Recon3D Fatal1ty Professional have only cosmetic differences, but considerable price difference: the Fatal1ty Professional, adds a beamforming microphone, some red LED lights and a metal shroud over the board, but has no real hardware improvements.[29][30]

Sound Blaster Z-Series

[edit]

The Sound Blaster Z-Series was announced in August 2012 and includes the PCI Express x1 cards, Z, Zx and ZxR which use the same Sound Core3D chip as the previous Sound Blaster Recon3D series.[31] The Z-Series improved sound quality over the Recon3D series by including more dedicated audio hardware such as Op-Amps, DACs, and ADCs.[32]

A Sound Blaster Z sound card
  • The Sound Blaster Z is the baseline card of the series. Some of its main features are Cirrus Logic 116 dB signal-to-noise ratio (SNR) digital-to-analog converters (DACs), a dedicated headphone jack with 600 ohm amplifier, and is bundled with a Beamforming Microphone that captures sound in a specific direction. One can switch between listening with headphones and desktop speakers in the Sound Blaster Z Control Panel. This card has a red color theme with a red LED light on the board. In addition to the red model, there is an OEM version that lacks the LED light, metal shielding and bundled microphone.
  • The Sound Blaster Z SE released in 2021 is identical to the Z, but with 7.1 channel virtual surround for compatible headphones, no bundled microphone and no driver CD as the card is only compatible with the Sound Blaster Command software.
  • The Sound Blaster Zx card is identical to the Z[31] (exact same card, exact same card SKU/Model (SB1500) on card itself, compared side by side in store), with the only notable change compared to the baseline "Z" being the addition of the desktop ACM (Audio Control Module). The Zx & ZxR were both bundled with the Audio Control Module (ACM) which is basically an extension cord for headphones. The ACM contains both 1/4" and 3.5 mm headphone and microphone jacks, a potentiometer headphone volume knob, and a built-in dual-microphone Beamforming array. The ACM uses a red color theme that matches the card. The entire package (Card and ACM) carries a separate model number of SB1506, which is different than the base SB1500 printed on the included card (as the card is just a SB-Z now bundled with accessories).[33]
  • The Sound Blaster ZxR is the top of line sound card of the series and uses an entirely different card from the Z and Zx. Some of its features include TI Burr-Brown 124 dB SNR DACs, two swappable op-amps, a 600 ohm 80 mW TI TPA6120 headphone amplifier, and 192 kHz stereo pass through. The Sound Blaster ZxR comes with a daughter board which provides optical S/PDIF input and output, and two RCA inputs that feature a TI Burr-Brown 123 dB SNR analog-to-digital converter (ADC); it has its own Sound Core3D processor and takes up a second expansion slot in the computer if installed. The ZxR can record up to 24-bit/96 kHz. The ACM and two boards (main and daughter) have a black color scheme with no LED lighting.

Sound BlasterX AE-5/Plus

[edit]

The Sound BlasterX AE-5 was announced in June 2017, the first discrete sound card made by Creative in five years since the introduction of the Z-series. The card is the first in the Sound Blaster series to use a 32-bit/384 kHz SABRE 32 Ultra DAC (ES9016K2M), along with a custom-designed discrete headphone amplifier (1 W output power and low output impedance of 1 Ohm so it can provide high damping factor for virtually any dynamic headphone). The card has an additional RGB lighting courtesy of a MOLEX power connection and accompanying RGB LED strip.[34][35] In late 2017, a white colored model of the sound card called the Sound BlasterX AE-5 Pure Edition was released with 4 RGB LED strips instead of one with the standard black model.[36]

In 2020, the AE-5 Plus was released which is similar to the previous model, but the sound card comes with hardware Dolby Digital Live and DTS encoding.[37] There is a white colored Pure Edition released alongside the standard black model.[38]

Connectors

[edit]

External connector

[edit]

Sound Blaster cards since 1999 conform to Microsoft's PC 99 standard for color-coding the external connectors as follows:

Color Function
Pink Analog microphone input.
Light blue Analog line level input.
Lime green Analog line level output for the main stereo signal (front speakers or headphones).
Black Analog line level output for rear speakers.
Silver Analog line level output for side speakers.
Orange S/PDIF digital output (sometimes used as an analog line output for a center and/or subwoofer speaker instead)

Up until the AWE line in 1994, Creative cards have short text inscriptions on the backplane of the card, indicating which port does what (i.e. Mic, Spk, Aux In, Aux Out). On later cards, the text inscriptions were changed to icons. With the latest cards from Creative, the cards were changed to use numbers as the ports are flexi-jacks and can have different functions assigned to them at run-time (i.e. changed from speaker output to mic in), but a color overlay sticker is included with retail units to help consumers identify the commonly used functions of the ports in their default modes.

Internal pin connector and jumper

[edit]

A lot of audio/data pin connectors and jumpers-setting is present in the internal body of the sound blaster, different from card to card, and along the years of productions.[46]

Most common pin connector:

  • Audio CD-IN, CD SPDIF and AUX-In
  • CD-ROM drive connection
  • PC speaker
  • TAD (Telephone Answering Device) connector
  • MB_PRO (Modem Blaster connector)
  • Wave Blaster Header

Most common pin jumper setting (especially before plug-and-play features):

  • Sound Card Base Address/IRQ/DMA
  • Line or Speaker output
  • MIDI
  • Joystick

Driver software modification (soft mod)

[edit]

Some drivers from the Audigy 2 ZS have been soft-modded by enthusiasts. These can be installed on Creative's older cards, including Sound Blaster Live!, Audigy, and Audigy 2. It has been claimed to offer improved sound quality, hardware acceleration of higher EAX versions in games, 64-channel mixing for Audigy 1, and an overall improvement in the card's performance. Several forum posts across the web have reported favorable results with this technique, excepting Live! users where the drivers only add the ability to use the newer software applications (i.e. the newer mixer applet). Comments on forums from developers of the software mod have said that Live's hardware is not capable of EAX3 nor 64-channels of hardware sound mixing.

Later, in 2004, Creative released updated drivers top-to-bottom for the Audigy through Audigy 4 line that put these cards basically at feature parity on a software level. As of 2006, the entire Audigy lineup uses the same driver package. DSP decoding at the driver level on other cards than Audigy 2 ZS and 4 is still not supported by official drivers, but it works with soft-modded drivers on the other cards with hardware DSP (like Audigy 2 6.1).

When Windows Vista was released, there was only a single beta driver for the Creative Audigy series that was usable on the operating system with minimal functionality and frequent instability reported by users. A Creative Forum activist named Daniel K. modified drivers from the X-Fi and applied it to the Audigy and Live! series, restoring most if not all of the features that came with the original XP setup CD in Vista. X-Fi drivers have noticeably better sound quality under Vista, and more bug fixes because of the newer build (last modified version is 2.15.0004EQ April). He managed to enable the X-Fi Crystallizer to work on Audigy series cards in software, however because of the patents involved, he was forced to remove all the modified drivers and DLL patch.

Creative then released a newer official Audigy Vista driver (2.18.0000 as of 28 July 2008) due to public and consumer pressure. However, some form of agreement between Creative and Daniel K has been achieved, as he returned to the Creative forums, posting updated versions of his modified drivers. He released the final version of his modded driver package as of January 12, 2012.[47]

Compatibility with Linux

[edit]

All recent[when?] Linux distributions support Sound Blaster Cards via kernel drivers. In case of non-Plug-and-Play ISA cards, a configuration file in /etc/modules must be reconfigured, writing for example with Sound Blaster 16 card installed: snd-sb16 isapnp=0.

X-Fi series cards have basic support in Linux, but the advanced features like signal routing, relay control or external I/O consoles are not supported.

Support for the newer Sound Blaster cards (Z and AE series) was added to the kernel during 4.19 – 4.20 release timeframe.

Precursors to Sound Blaster

Creative Music System

The Creative Music System (C/MS), released by Creative Labs in 1987, served as the company's inaugural foray into PC audio hardware and acted as a direct precursor to the Sound Blaster lineup. Designed for PC and compatible systems, it provided basic music synthesis capabilities at a time when built-in PC audio was limited to simple beeps from the system speaker. This internal 8-bit ISA expansion card featured two SAA1099 programmable sound generator chips, delivering 12 channels of square wave synthesis with output and noise generation for rudimentary sound effects. Connected via the PC's ISA bus, the C/MS included bundled software like the Intelligent Organ, a composition tool that enabled users to create and play simple melodies using keyboard inputs or predefined instrument emulations. Lacking digital audio recording or playback capabilities and MIDI connectivity, the card was primarily suited for chiptune music in early PC games, such as those employing basic waveform tones for backgrounds and effects. Its focus on affordable synthesis made it accessible for hobbyists and gamers seeking enhanced audio without complex setups. Market reception was strong, particularly in Asia, where the C/MS proved lucrative for the fledgling Singapore-based firm and established Creative as a key player in emerging PC peripherals; it later evolved into the domestically rebranded Game Blaster for wider international adoption.

Game Blaster

The Game Blaster, model CT1300, was released in 1988 by Creative Labs as an 8-bit ISA sound card targeted at PC gamers. It was a rebranded and repackaged version of the Creative Music System for the North American market, sold through retailers like . It utilized two SAA1099 programmable sound generator chips to deliver 12 channels of square-wave stereo sound plus noise generation capabilities. The card's synthesized audio enabled support for early game audio in titles from developers like Sierra On-Line. It had no native MIDI support. Priced at $99, the Game Blaster was bundled with CMS-compatible software for use with applications. It provided a foundational upgrade path to the Sound Blaster 1.0, which preserved for its audio features.

First-Generation Sound Blasters (8-bit ISA and MCA)

Sound Blaster 1.0

The Sound Blaster 1.0, released in 1989 by Creative Labs, represented the inaugural entry in the renowned series, designated under model numbers CT1310 and CT1320. Engineered as an 8-bit ISA , it integrated the Yamaha YM3812 FM synthesizer—commonly known as the OPL2—for 9-channel (9 melodic voices or 6 melodic + 5 percussion in drum mode) music synthesis, alongside an 8-bit mono (DAC) supporting playback at up to 22 kHz and an (ADC) enabling recording at 13 kHz. This combination introduced practical handling to PC-compatible systems, bridging the gap between basic beeper output and more sophisticated sound reproduction. A pivotal innovation was the card's inclusion of a dedicated (DSP) chip, which facilitated 8-bit digital audio playback and recording, albeit in half-duplex mode that precluded simultaneous operations. It achieved backward compatibility with the AdLib card via the OPL2 chip's register interface and with the earlier Game Blaster through onboard SAA1099 (CMS) chips for square-wave synthesis, allowing seamless integration with existing software libraries without requiring modifications. These attributes distinguished the Sound Blaster 1.0 from prior offerings, establishing it as a comprehensive audio solution that combined synthesis, sampling, interfacing via a UART, and a joystick port on a single board. Upon launch, the Sound Blaster 1.0 was bundled with driver software, diagnostic utilities, and demonstration programs showcasing its FM music and sampled audio features, which quickly gained traction in emerging PC games utilizing digitized sound effects for enhanced immersion. Its reception highlighted its role in revolutionizing PC gaming audio, moving beyond monochromatic beeps to dynamic soundscapes that elevated titles like early adventure and action games, while its versatile compatibility propelled widespread adoption. The card outsold competitors such as the AdLib, capturing significant market share and solidifying Creative Labs' position as a leader in PC multimedia hardware. Production variants included the CT1320 with soldered CMS chips for fixed Game Blaster support; later revisions like the CT1320C provided sockets for optional CMS installation to reduce costs for users without that need, though these are associated with the 1.5 update. Both included a input for recording. Initially priced at $299, it offered strong value for its capabilities, though later 1.x revisions addressed early reliability issues in components like the DSP .

Sound Blaster 1.5 and 2.0

The Sound Blaster 1.5, released in 1990 under model designation CT1320C, offered incremental enhancements to the original Sound Blaster lineup while preserving with existing software. This version adopted the DSP chip revision 2.00, which introduced auto-initialized DMA support for digitized audio playback. This feature enabled continuous background music reproduction by allowing the DMA controller to loop the audio buffer automatically, reducing CPU overhead and improving seamless integration in multitasking applications or games. The CT1320U served as an OEM variant, designed for embedding in complete PC systems by manufacturers. Creative Labs targeted cost efficiencies with the Sound Blaster 1.5 by making the Creative Music System (C/MS) chips optional via sockets rather than including them by default, a change from earlier models. The card adhered to the 8-bit ISA bus architecture and supported 22 kHz mono sampling for playback and 13 kHz for recording, leveraging the Yamaha YM3812 (OPL2) FM synthesizer for AdLib-compatible music synthesis. The Sound Blaster 2.0, model CT1350 and launched in October 1991, built on these foundations with refinements aimed at production efficiency and audio quality. It featured an upgraded DSP version 2.01 for enhanced performance in digital audio handling, alongside a dedicated mixer chip (CT1335) that provided finer volume adjustments, including 8-level controls for master, MIDI, and CD inputs, and 4-level control for voice. The board's more compact layout integrated components tightly, contributing to its positioning as a budget-oriented option in the 8-bit Sound Blaster series while maintaining the 22 kHz playback sampling rate standard.

Sound Blaster MCV
