I want to use Python to access a wav-file and write its content in a form which allows me to analyze it (let\'s say arrays).
audiolab seems to be not maintained anymore, you should try PySoundFile.
Installation is simple:
pip install PySoundFile --user
And reading a sound file as well:
import soundfile as sf
x, fs = sf.read('/usr/share/sounds/purple/receive.wav')
Have a look at this overview about different Python libraries for handling sound files.
