The Python package audiofile handles all kind of audio files with a focus on reading speed_.

It can read and request information on channels, duration, number of samples and sampling rate for all files that are supported by ffmpeg_, sox_, and mediainfo_. In addition, it can write WAV, FLAC, MP3, and OGG files.

Have a look at the installation_ and usage_ instructions as a starting point.

Code example for reading a file:

.. code-block:: python

import audiofile

signal, sampling_rate = audiofile.read("signal.wav")

Under the hood it uses soundfile_ to read the audio files, converting non-supported formats first to WAV files. The same approach is applied when requesting duration for formats that need to be decoded to ensure that duration and number of samples match.
