# StemGMD

This repository mirrors the StemGMD archive files released on Zenodo as "StemGMD: A Large-Scale Audio Dataset of Isolated Drum Stems for Deep Drums Demixing".

StemGMD builds on Magenta's Groove MIDI Dataset. The upstream authors mapped the original 22 MIDI pitches to nine canonical drum instruments and synthesized isolated 16-bit/44.1 kHz stereo WAV stems with ten Logic Pro X acoustic drum kits. The release contains 1224 hours of audio, corresponding to more than 136 hours of full-kit mixtures, plus single hits at ten velocities. The fully extracted dataset requires just over 1.13 TB.

This mirror preserves the upstream archive files and provides a metadata-only dataset viewer manifest. It intentionally does not expand every WAV file into the viewer because the dataset is very large.

## Files

See `metadata.csv` for archive names, sizes, MD5 checksums, source URLs, and paths in this repository.

## Reconstructing the Dataset

Download all files under `archives/` into one directory, then run the upstream `unzip_StemGMD.sh` script from that directory. The extracted dataset is expected to require just over 1.13 TB.
