Implement a bunch of simple estimators #2

Closed elvijs closed 4 months ago

elvijs commented 5 months ago

Trivials

The 0-model (always need the zero model) :)
The 100-model

Librosa direct

A parametrised librosa.beat.beat_track version (so we can search over hyperparameters)

Others

A manual librosa decision tree. Get an initial tempo estimate via beat_track. Then try again, but now seed start_bpm with the estimated value. Explore the harmonics and decide the best value based on some sort of empirics.
Truncator - slap on a decorator that cuts off the start and the end of the song. Weird starts and ends may be throwing the algo off. Make this parametrisable, so we can do hyperparam search.
