The note model used by MlNoteDetector (src/audio/MlNoteDetector.cpp) for TST-style polyphonic note detection.

  • Source: the basic-pitch PyPI package, v0.4.0 — basic_pitch/saved_models/icassp_2022/nmp.onnx, copied here verbatim.
  • Upstream: Spotify Basic Pitch — https://github.com/spotify/basic-pitch
  • License: Apache-2.0 (see the upstream LICENSE).
  • SHA-256: 2c3c1d144bfa61ad236e92e169c13535c880469a12a047d4e73451f2c059a0ec
  • I/O contract: input [batch, 43844, 1] float32 (~2 s mono @ 22050 Hz); outputs onset / note / contour posteriorgrams. See tests/spike/README.md for the verified contract.

Bundled into the packaged app via electron-builder's extraResources (Constitution IV — offline first-run). When the file is absent the engine falls back to the YIN PitchDetector / ChordScorer (Constitution VII).
