# MDB Drums ++

This repository contains updated annotations for the MDB Drums dataset, which itself consists of drum annotations and audio files for 23 tracks from the [MedleyDB](http://medleydb.weebly.com/) dataset.

## Contents

- Audio: drum-only WAVs in `audio/`
- Annotations: MIDI files in `annotations/midi/`
- Logic Pro sessions: `.logicx` in `logic_sessions/`
- Metadata: `metadata.csv` with one row per track

`metadata.csv` columns:

| track_id | style | split | audio_path | midi_path | logic_project_path | sample_rate_hz | num_channels | duration_sec | license | source | notes |
| :-- | :-- | :-- | :-- | :-- | :-- | --: | --: | --: | :-- | :-- | :-- |

All file paths are relative to the repo root. Durations are derived from WAV headers.
