Check this short video showcasing the work I did in collaboration with Juhan Nam. It shows a real-time music visualizer and auto-tagger developed using the pipeline presented in this paper. We call it SAFVY! (Sparse Audio Feature Visualizer, Yeah!).
Note: this video uses copyrighted material (some very well know songs), but I think this is "fair use" as stated in the Copyright Act of 1976, given the scholarship and research usage of them. If you are the owner of the copyrighted material and don't think that's the case, please contact me.
