I thought they use Cepstrum followed by machine learning.
- a-dub 4y agowindows fingerprinted by distances and angles between spectral peaks. robust to noise but not warping in time or frequency domains. fingerprints stored in a scalable lsh style lookup table. (iirc) with the goal of a fast, scalable lookup table for all the 30s windows in all recorded music.
- memling 4y ago> robust to noise but not warping in time or frequency domains. Could you use something like a dynamic time warping algorithm for this? (I'm not super acquainted with the technique and not sure if you could get away with it in the frequency domain used for the matching.)
