What does librosa load do?
load. Load an audio file as a floating point time series. Audio will be automatically resampled to the given rate (default sr=22050 ).
Can librosa load mp4?
Since librosa can load MPEG4 audio (when suitable dependencies are installed), I would recommend downloading that, and loading it directly.
Can librosa load mp3?
This warning will always occur when loading mp3 because libsndfile does not (yet/currently) support the mp3 format. Librosa tries to use libsndfile first, and if that fails, it will fall back on the audioread package, which is a bit slower and more brittle, but supports more formats.
