This release adds two features where you can specify

  • the step size to use (#18) for performing pitch estimation: --step-size, and
  • the model capacity (#20) to run pitch estimation with a smaller model --model-capacity.

Refer to the command line help crepe --help for detailed usage.

These features provides a trade of between the computation time versus the time resolution or slightly lower accuracy, and it can be especially useful when running CREPE on CPU (#19).

Here are some ballpark numbers for running CREPE on a 54.31s-long WAV file with various parameters, showing you can get up to 20 times at the cost of slightly lower time resolution and accuracy:

full (default) large medium small tiny
10 ms (default) 91 s 60 s 35 s 15 s 9.1 s
20 ms 47 s 31 s 19 s 9 s 6 s
50 ms 20 s 14 s 9 s 6 s 4 s

The above are the real time reported by time CUDA_VISIBLE_DEVICES=-1 crepe -s {step} -c {capacity} audio.wav, on a i7-6600K CPU.
