At a high level, "Dissect" includes pipelines to analyze and index audio (mostly music) in experimental ways. The end goal is to programmatically create new, interesting, original, and experimental music from the components of other music.
I use demucs to source separate a lot of files and Magenta's MT3 to transcribe everything to midi. I store metadata for all those files in a LevelDB instance.
So far I've conducted these experiments with around 15k original + separated audio files.
