Read MP3 in Python3

Question

I am a beginner in Python and so I am using Python 3 for the following :

mp3 = read_mp3(mp3_filename)
audio_left = mp3.audio_channels[0]
 

where audio_left will contain raw PCM audio data.

I was looking at Play a Sound with Python, but most of the suggested modules are not ported to Python 3 yet. If possible I'd like to avoid having to install a fully-fledged game dev library. Is there any way?

Answer 1

It is easier to convert the file from mp3 to wav with some tools such as :

$ ffmpeg -i foo.mp3 -vn -acodec pcm_s16le -ac 1 -ar 44100 -f wav foo.wav
or
$ mpg123 -w foo.wav foo.mp3
 

Then read the WAV with one of the python WAV libraries. I'd recommend PySoundFile because it works with most generated WAV correctly and installed without issue. Hope this helps.
