ADPTR Audio is a London-based audio software company founded by mix engineer and developer Marc Adamo, whose earlier work included Sample Magic's Magic AB reference plugin and the book The Secrets of House Music Production. The brand develops its plugins in partnership with Plugin Alliance, which handles distribution, and positions its tools around modern mixing, mastering, and streaming-era workflows.

The catalog centers on a handful of focused processors: Metric AB, a reference tool for A/B-ing a mix against commercial tracks and spiritual successor to Magic AB; Streamliner, which models playback across streaming platforms such as Spotify, Apple Music, and YouTube Music; Sculpt, a broadband dynamics and transient processor; Hype, a multi-band enhancer combining compression, harmonic generation, and stereo placement; and Utopia, a spectral reverb built around an algorithm by Geraint Luff of Signalsmith Audio.

ADPTR Audio has 6 products cataloged on Equipboard, including Spectral Analysis Plugins, Mastering Plugins, and Utility Plugins. Their gear is featured by 1 artist, with the strongest followings in Electronic, Pop, and K-pop. Notable users include Alawn.
