Pydub lets you do stuff to audio in a way that isn't stupid. As mp3 download.
Make the beginning louder and the end quieter
Concatenate audio (add one file to the end of another)
AudioSegments are immutable
Crossfade (again, beginning and end are not modified)
Fade (note that you can chain operations because everything returns an AudioSegment)
Save the results (again whatever ffmpeg supports)
Save the results with tags (metadata)
You can pass an optional bitrate argument to export using any syntax ffmpeg supports.

Any further arguments supported by ffmpeg can be passed as a list in a 'parameters' argument, with switch first, argument second. Note that no validation takes place on these parameters, and you may be limited by what your particular build of ffmpeg/avlib supports.
Most issues people run into are related to converting between formats using ffmpeg/avlib. Pydub provides a logger that outputs the subprocess calls to help you track down issues:
Don't worry about the temporary files used in the conversion. They're cleaned up automatically.
Installing pydub is easy, but don't forget to install ffmpeg/avlib (the next section in this doc)
Or install the latest dev version from github (or replace
with a release version like
pip install git+https://github.com/jiaaro/pydub.git@master
Copy the pydub directory into your python path. Zip here
You can open and save WAV files with pure python. For opening and saving non-wav files – like mp3 – you'll need ffmpeg or libav.
You can play audio if you have one of these installed (simpleaudio strongly recommended, even if you are installing ffmpeg/libav):
ffplay (usually bundled with ffmpeg, see the next section)
avplay (usually bundled with libav, see the next section)
folder to your PATH envvar
Ogg exporting and default codecs
The Ogg specification ( http://tools.ietf.org/html/rfc5334 ) does not specify the codec to use, this choice is left up to the user. Vorbis and Theora are just some of a number of potential codecs (see page 3 of the rfc) that can be used for the encapsulated data.
When no codec is specified exporting to

Suppose you have a directory filled with mp4 and flv videos and you want to convert all of them to mp3 so you can listen to them on your mp3 player.
