@audio/mir-transcribe

Polyphonic transcription — @audio/mir-multif0 frames tracked into note events by pitch continuity: consecutive frames within ±60 cents extend a note, gaps close it, short notes are dropped. Velocity from median frame salience.

npm install @audio/mir-transcribe

import transcribe from '@audio/mir-transcribe'

let notes = transcribe(data, { fs: 44100 })
// Array<{ time, duration, midi, freq, velocity }>

Options: everything @audio/mir-multif0 takes (fs, frameSize, hopSize, minFreq, maxFreq, maxPitches, harmonics, threshold), plus - minDuration — shortest kept note (default 0.08, seconds) · maxGap — frames a pitch may drop out before its note closes (default 1)

Also exported as an audio.js stat manifest (./audio).
