About

Roomtone

Features
Read full description

Roomtone is a lens that transforms the sounds around you into ambient music, in real time. Sounds picked up by the microphone are dissolved, stretched, and reshaped into a new space. The quiet of your room, rain, the hum of an air conditioner, distant voices — ordinary surroundings become music that exists only in that moment. The same sound never plays twice. TAPE DECAY — vast silence of a worn-out tape LABYRINTH — folding echoes POOL — ripples beneath the surface PRISM — sound, refracted INNER BODY — pulse from within RAIN DESK — rain on your desk PROMENADE — music for walking DEEP SEA — pressure of the deep CHOP COLLECTOR SATOSHI — collected fragments MANHOLE — resonance underground LAST TRAIN — after the last train Best experienced with headphones. Background playback supported. No recording, no storage, no transmission. No network connection. No tracking, no account, no ads.
