appologies for the late response though.. do you think you can pivot your dependency from librosa to pydub. for better cross platform dependencies.. I recently shifted the project's dependency from librosa to pydub due to issues in windows and rasspberry pi

[pythonbrad]

@TheSeriousProgrammer, pydub depends on ffmpeg but I want minimal dependencies on my environment.

[pythonbrad]

@TheSeriousProgrammer, this is the cost to install ffmpeg.
I deploy my application using docker, and have the minimal size and deployment time, is good for me.

Hmm .. we can migrate to soundfile but we won't be able to generate reference files from file types other than the wav format.. let me see..

[TheSeriousProgrammer]

have made the pivot to soundfile and added a couple of other features tooo.. check it out and let me know

[pythonbrad]

@TheSeriousProgrammer, it works with my change.
Also soundfile support mp3, i tested with mp3 and it worked!

[TheSeriousProgrammer]

Just now saw that a recent version of sndfile does support mp3... will test it myself too once. and then include it back
