CoverageActive stem segments from MUSDB18 (drums, bass, vocals, accompaniment, mixture)
Time span2025
Scale99,134 files, total size 15 GB

Contents & fields

The dataset contains active stem segments extracted from MUSDB18, structured under extracted_stems/ with train/ and test/ subdirectories, each containing drums, bass, vocals, accompaniment, mixture folders, and a metadata/ folder with JSON files. Audio is 22.05 kHz mono. When loaded via Hugging Face datasets, each sample includes the following fields:

  • audio——audio array and sample rate
  • stem_type——type of stem (e.g., drums, bass)
  • track_name——track name

Research uses

Suitable for music source separation, deep learning model training and evaluation, especially analysis of active vs. inactive audio segments.

Why this is hard to get on your own

When needing to work with MUSDB18 but focusing on active audio segments to improve training efficiency, a ready-to-use active segment extraction version is lacking.
