Pocket Audio is a Toronto-based music technology company founded by Andrew Oliver, known for the HiChord — a pocket-sized chord synthesizer, looper, and drum machine designed to let players perform full songs without music-theory knowledge. The device uses a seven-button chord layout based on the Nashville Number System, a joystick for live chord transformations, and packs a 12-oscillator digital synth engine, a dual-track looper, a drum machine, a vocoder, and a sampler into a handheld aluminum or plastic chassis.

The HiChord is designed in Toronto and assembled in Penang Science Park, Malaysia. It runs on the Electrosmith Daisy platform and offers 30+ instrument voices, 84,000+ chord voicings, a built-in speaker, USB-C MIDI, and a companion web app for sound design. The project was funded on Kickstarter, where it hit its goal in roughly two minutes after going viral on TikTok, and it has since shipped in multiple batches including Standard and Aluminum Editions in jet black and silver anodized finishes.

The company's output centers on the HiChord line rather than a broad product catalog, positioning it alongside other pocket-format instruments in the independent synth and groovebox space. Units are sold direct through the brand's shop as well as through retailers such as Perfect Circuit, Chicago Music Exchange, and Soundgas.

Pocket Audio has 1 product cataloged on Equipboard, including Synthesizers. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include hijaq..
