Field notes
The page describes an in-browser transcription pipeline using Basic Pitch, with audio decoded locally and analyzed in 30-second segments by a background worker. It sets a 10-minute or 200 MB file ceiling, citing browser memory limits, and says conversion took 96 seconds for a 30-second clip in its own test. Detected parts are combined into one MIDI track; separating instruments is outside the tool's scope.
