 I got as far as tracking the varying tempo by Viterbi path through a (low sampling rate) spectrogram of the original onset envelope. ​ I adapted the beat tracker to use local tempo constraints,​ but then I got very concerned about aligning the tempo changes correctly to the original audio. ​ This took me down a rabbit hole of exactly what we want the onset envelope at time T to correspond to ... which will probably end up with better beat tracking in the future. I got as far as tracking the varying tempo by Viterbi path through a (low sampling rate) spectrogram of the original onset envelope. ​ I adapted the beat tracker to use local tempo constraints,​ but then I got very concerned about aligning the tempo changes correctly to the original audio. ​ This took me down a rabbit hole of exactly what we want the onset envelope at time T to correspond to ... which will probably end up with better beat tracking in the future.
