Slakh2100 (Synthesized Lakh Dataset)

Introduced by Ethan Manilow et al. in Cutting Music Source Separation Some Slakh: A Dataset to Study the Impact of Training Data Quality and Quantity1 Jan 2019 archive 2025-07-28

The Synthesized Lakh (Slakh) Dataset is a dataset for audio source separation that is synthesized from the Lakh MIDI Dataset v0.1 using professional-grade sample-based virtual instruments. This first release of Slakh, called Slakh2100, contains 2100 automatically mixed tracks and accompanying MIDI files synthesized using a professional-grade sampling engine. The tracks in Slakh2100 are split into training (1500 tracks), validation (375 tracks), and test (225 tracks) subsets, totaling 145 hours of mixtures.
