GoKawiilBinaural Studio
A local-first browser studio for building long-form headphone sessions from binaural tones, music, adaptive textures, and spoken-word audio.
Binaural Studio combines a ten-voice binaural synthesizer with a local music deck, an independent spoken-word deck for audiobooks and other long-form audio, and a real-time master recorder. It can analyse your music in the browser, tune the generated layer to each track, move between state presets during a set, and record the complete result as one audio file. There is no backend, account, build step, or audio upload.
Launch Binaural Studio → — no installation required.
Use stereo headphones and start at a comfortable volume. The state presets are creative sound-design tools, not medical treatments.
