@audio/midi-parse

Standard MIDI file parser — tracks, tempo map, note events

SMF 0/1 reader: header, tracks, running status, variable-length deltas, tempo map (all set-tempo events applied across tracks), and a flattened note list with absolute seconds.

import parse from '@audio/midi-parse'

let { tracks, tempos, notes, duration } = parse(smfBytes)

parse(buf: ArrayBuffer|Uint8Array) → { format, division, tracks, tempos, notes, duration }

Each note: { time, duration, midi, velocity, channel, track } — time/duration in seconds, velocity normalized 0..1. tempos: [{ tick, time, usPerBeat }].

Install

npm i @audio/midi-parse
