Thanks for your amazing work!
I have a question about your dataset mixing strategy. Does mixture here refer to:

1. a combination of audios from different datasets so no change per training audio, or
2. a superposition of different audio tracks, so each training audio contains multiple tracks from multiple datasets?

[Alexandre Défossez]

this is the sum of two audio from two different datasets (sometimes even 3 audio).
