Whenever I try to load any audiofile with librosa I get the following error:

import librosa
filename = librosa.util.example_audio_file()
librosa.load(filename)

I have ffmpeg which I have verified works and all other dependencies installed. I am at a total loss of how to resolve this any could use any and all help

wontfix Issues that we don't want to deal with: out of scope, intended behavior, deprecations, etc. labels Mar 26, 2017

@chausies yes: libsndfile does not support mp3 (though there's an open PR now), and that's a deal-breaker for many librosa users.

When libsndfile does get mp3 support, we'll revisit the load implementation and see if it makes sense to swap out the dependencies.

This issue is officially fixed for audioread on Windows Subsystem for Linux as of today:
beetbox/audioread#51

It may be a bit before the pypi version is updated though.
