SunVox, also known as SunVox Modular Music Creation Studio, is a 2008 music creation tool built around the SunVox Engine, a software-based modular synthesizer and tracker-based sequencer. It is available for multiple platforms including Windows, MacOS, Linux on the desktop and iOS, Android in the mobile sphere. The desktop versions are freely available for download on the developer's website while a paid version for iOS and Android apps, respectively, is purchasable from those platforms' official app stores. There was also, at one time, a release for Palm OS devices.

The underlying SunVox engine was developed as free software under the BSD License prior to version 1.4.

SunVox can be broken down into four main sections as shown:

Module view is where your instruments and effects located; every unit of instruments and effects is represented as a rectangle called modules. These modules not only are used for generating or modifying sounds, but also give visual feedback by displaying various type of oscillation signal. Modules have three main type, which they are:

These are the oscillators of SunVox, acting as your sound source, including subtractive, FM, samples, drum, and a FFT (Fast Fourier Transform) based additive synthesizer.

SunVox also includes a handful of effects to modify the sound from your synth module, from basic module like filter, delay, echo and reverb, to something more complex like FFT, and pitch shifter.

modules that do not fit into the two categories above are located in misc. They are generally used for modifying control or midi signal, such as multiCtl (controller multiple controller at different module), multisynth (sending midi signal to multiple synths), sound2ctl (converting audio signal into control signal for controllers), and feedback (the only way for doing feedback loop in SunVox). MetaModule is notable in this category because this loads another SunVox project within the current project as a module, which is useful for loading multiple SunVox project at once, or designing customized synth and effect modules.

Located at the left side of the screen, controller view list all the control at the selected module at the module view; user can manipulate the controller to change the sound of a module, and you can also assign automation into a pattern by shift-clicking a controller. The controller also have options for mute, solo or bypass the module, to ignore some of the sound during sound design. If the controller list is too long, the V option can display the controller in one, two or four columns, reducing the length of controller for complex MetaModule or FMX.
