Kotaro Asahina

Artist / Founder, Kuon R&D

朝比奈 幸太郎Kotaro Asahina

Music, recording art, acoustics, software, hardware — five domains spanned and united by a single mind. Founder of Kuon R&D and heir to Kaneda-style DC recording.

Music

A pianist, bound for Europe

Studied ethnomusicology and became a pianist. Explored improvisation with Lindha Kallerdahl in Sweden; made an album with Achim Tang in Cologne, where Stephan Desire taught him acoustics.

Recording

Inheriting Kaneda DC recording

Back in Japan, studied under the leading authority Akihiko Goto — directly inheriting a purity of sound, half a century in the making, unreachable by commercial equipment.

Software

Describing the world in software

Learned C and GPS positioning from Kazuhide Kobayashi of Geosense. Builds a browser-native music platform solo — frontend, audio engine, payments and all.

Hardware

The feel of hardware

Restores Switzerland's legendary Revox decks himself — reading boards, soldering, verifying. That touch lives in the P-86S / X-86S microphones.
