Listen to generated music by measuring it and by reading it as sheet music: render Strudel code or record a Web Audio page through the real engine in headless Chromium, then read spectrograms, pYIN pitch lines, chroma, roughness and semitone-rub meters; engrave notes as a score with beat-by-beat harmony; transcribe a melody from audio; read MusicXML/MIDI/ABC or a score image into notes and into Strudel code. Use to check whether generated music sounds right or better (before/after a change), to match a reference track, spectrogram image or score, or to find discordant chords, a buried melody, clipping or muddy mixes. Triggers on 'does it sound better', 'listen to', 'render and check', 'spectrogram', 'sfft/stft', 'discordant', 'clashing chords', 'sounds off', 'compare to the original', 'reproduce this track in Strudel', 'sheet music', 'score', 'notation', 'MusicXML', 'MIDI', 'ABC', 'transcribe', 'OMR'. Pairs with strudeling (writing Strudel); for format conversion use processing-video.

listening-to-music - Changelog

All notable changes to the listening-to-music skill are documented in this file. The format is based on Keep a Changelog.

[0.2.0] - 2026-09-25

Other

  • listening-to-music 0.2.0: sheet music in and out

[0.2.0] - 2026-09-25

Added

  • Sheet music, both directions, on a shared events JSON (notes.py):
    • score.py: engrave events as a score (music21 + Verovio PNG), key-aware spelling, --harmony beat-by-beat chord names, Roman numerals and rub flags, --zoom for high-resolution pages.
    • transcribe.py: monophonic melody (and --bass) from audio with glide folding, gap merging, onset snapping and pitch-specific re-attack splitting (--no-split for echo-heavy leads).
    • compare_notes.py: mir_eval note precision/recall/F1 with and without offsets, unmatched notes listed, --align for unknown downbeats, --octave-free.
    • read_score.py: MusicXML/MXL/MIDI/ABC/Humdrum, music21 corpus, and images/PDF via oemer OMR, into events.
    • to_strudel.py: events into Strudel code, one <...> step per bar.
  • SKILL.md section with measured accuracies (round trip 100%, transcription 87%/82%, OMR 6%, reading engraved images directly 100% on a blind test).

[0.1.0] - 2026-09-25

Added

  • render_strudel.mjs: render Strudel code through superdough in headless Chromium to a float WAV; --events dumps per-layer note events.
  • record_page.mjs: record any Web Audio page (click, seed hook, warm-up), served from an https origin so AudioWorklet synths play.
  • spectrogram.py: note-axis CQT spectrogram with pYIN lead line and chroma, plus features in .npz.
  • roughness.py: Sethares roughness per frame; --pair compares replicated before/after takes against take-to-take spread.
  • reference.py: decode a reference spectrogram image (colormap inversion, tick calibration, drawn pitch line) and compare a render against it.
  • clashes.py: note-level scan for semitone and minor-ninth rubs by layer pair.
  • rubs.py: audio-side rub meter (CQT peaks at 3 bins per semitone; share of tonal energy in semitone and minor-ninth pairs), with --pair replicate comparison.
