Audio-Technica Corporation (株式会社オーディオテクニカ, Kabushiki Kaisha Ōdio Tekunika) (stylized as audio-technica) is a Japanese company that designs and manufactures professional microphones, headphones, turntables, phonographic magnetic cartridges, and other audio equipment.

Audio-Technica was established in 1962 in the Shinjuku district of Tokyo, Japan, by Hideo Matsushita as a phonograph cartridge manufacturer. Its first products were the AT-1 and the higher-end AT-3 MM stereo phono cartridges. Business rapidly developed, with the company starting to deliver cartridges to domestic audio manufacturers, and Audio-Technica expanded into other fields. The headquarters and factory moved to the current address in Naruse, Machida, Tokyo in 1965. In 1966, a test record entitled Moving Pulse (AT-6601) was released to help prove Audio-Technica's quality. In 1967, the company made a technological advance, releasing the AT-35X as the first ‘VM’ type stereo cartridge. This design increased growth in global exports, and the paten was extended across Switzerland, Canada, the UK, US, and West Germany. In 1969, the company began exporting phono cartridges worldwide and launched the first microcassette recorders.

In 1972, Audio-Technica established its US arm in Fairlawn, Ohio, and started shipping VM phono cartridges to European manufacturers. In 1974, the company developed its first headphones, the AT-700 series, which launched the same year. In 1977, celebrating its 15-year anniversary, Audio-Technica released second-generation models of dynamic headphones in the ATH-3, ATH-4, and ATH-5. That same year, the company developed and released the dual moving-coil MC-type AT-34 stereo cartridge. The AT-800 series of microphones were introduced in 1978, moving Audio-Technica into the commercial microphones market, and in the same year, the UK establishment in Leeds began operation.

In the 1980s, with the growth in digital music formats threatening its core business of phonograph cartridges, Audio-Technica began a period of diversification. Employee suggestions were solicited, with sushi machines among the ideas selected for further development.

In 1984, Audio-Technica introduced the ASM50 Nigirikko, a nigiri-forming appliance for home kitchens, which incorporated a turn-table like mechanism to deposit the nigiri onto. The market success of this product led the company to develop a range of sushi machinery for commercial and industrial use. Audio-Technica remains one of the largest manufacturers of sushi machines globally today, with products marketed under the brand AUTEC.

In 1981, a moving-coil cartridge that used diamond, specifically the AT1000 featuring a diamond cantilever, was introduced. That same year, the now long-selling AT33E was released.

In 1986, the company developed RCA cables with high-purity copper produced from the continuous metal casting process, "Pure Copper Ohno Continuous Casting" (PCOCC), invented and developed between 1982 and 1985 by Atsumi Ohno. In the same year, the company launched the AT33ML/OCC phono cartridge, the first made with PCOCC materials. In 1987, the AT-OC9 was released. This is the original cartridge model from which today’s fourth-generation AT-OC9X series evolved. In 1988, another Audio-Technica subsidiary was founded in Taiwan.

In 1990s, Audio-Technica introduced several large-diaphragm condenser microphones for studio use: the AT4033 cardioid microphone in 1991, the AT4050 multi-pattern in 1995, and the AT4060 vacuum tube cardioid microphone in 1998. The AT895, a DSP-controlled five-element microphone array providing adaptive directional audio acquisition, was introduced in 1999. In 1996, the Southeast Asian establishment began operation in Singapore.
