Interesting, I attempted to do the same as you but stopped just shy of BPM matching. However I did get sound similarity working using an audio tagging neural net [1]. I chopped off the first and last 15 seconds of every song in my collection and ran them all through this analysis which produces a ~520 dimensional vector. I then targeted specific endings I wanted to match and used Euclidian distance to find the closest matching song beginning. YMMV but I thought it actually worked pretty well, I just never got to automating the BPM matching. I can try to look for my old script if you're interested :) [1] https://github.com/fschmid56/EfficientAT https://github.com/fschmid56/EfficientAT
