Apogee Electronics is an American pro audio manufacturer headquartered in Santa Monica, California, founded in 1985 by Betty Bennett, Bruce Jackson, and Christof Heidelberger. The company first gained recognition for its 924 and 944 anti-aliasing filters, which were used in high-end Sony and Mitsubishi digital recording systems to improve the sound quality of early compact discs. Apogee went on to become one of the most respected names in digital audio conversion and audio interface design, producing a wide range of AD/DA converters, audio interfaces, and recording tools used across music, film, and broadcasting.

Apogee's product line spans from compact portable interfaces like the Duet and ONE to professional multi-channel systems like the Symphony I/O Mk II and the Ensemble Thunderbolt. The company also produces iOS-compatible recording tools such as the MiC and JAM, and has expanded into audio plugins. Other notable products include the Big Ben master digital clock, the AD-8000 converter, and the Symphony Desktop interface with vintage mic preamp emulation.

The company operates Apogee Studio in Santa Monica, an in-house recording studio and performance venue managed by mixing engineer Bob Clearmountain (known for his work with Bruce Springsteen, The Rolling Stones, and Bryan Adams). The studio has hosted live sessions for KCRW featuring artists including David Gray, Ryan Adams, Patti Smith, Vampire Weekend, Nick Cave and the Bad Seeds, Beck, and John Mayer.

Apogee has 115 products cataloged on Equipboard, including Audio Interfaces, Condenser Microphones, and A-D & D-A Converters. Their gear is featured by 317 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Ola Englund, Flume, and Mac DeMarco. Apogee's catalog spans the full price spectrum — from entry-level options to high-end flagships.
