# NoteGrab training data

Two million score-addressed note targets from 100,696 synthetic mixtures,
plus eight recorded-scene shards. A mixture may be reused for several target
notes. Each index row identifies the mixture, requested note, and waveform data.

| Path | Contents |
| --- | --- |
| synthetic/ | Synthetic audio, training-row index, timing and sampling metadata. |
| recorded/ | Recorded scenes, isolated note targets and their indexes. |
| example/ | One unpacked mixture, isolated target, reference sound and note labels. |
| manifest.json | File inventory, compression information and training path mappings. |

Download and restore the package from the NoteSep repository:

```sh
uv run notesep download-data --repo-id ben2002chou/notesep-training-data --output data/notegrab
```

Setup verifies the files, decompresses audio shards, and writes path-map.json
for training. The compressed download is about 446 GB. Restored data occupies
about 2.39 TB; allow space for both during setup. Audio values are preserved
exactly. The training guide in the code repository gives the training command.

Start with example/ to listen to a training row. The larger files are indexed
containers for efficient training, rather than directories of individual WAVs.
ASO uses separate source-complete scenes and locally generated NoteGrab estimates.

`synthetic/sampling-parent.json` selects the rows for the original 30,000-update
parent run. `synthetic/sampling.json` selects rows for the later continuation.
The intermediate 250-update stage uses `synthetic/sampling-adaptation.json`
and the instrument-library labels in `synthetic/render-methods.npz`. All three
row selections refer to the same audio and row index.
