Reading *.wav files in Python

I need to analyze sound written in a .wav file. For that I need to transform this file into set of numbers (arrays, for example). I think I need to use the wave package. However, I do not know how exactly it works. For example I did the following: import wave w = wave.open('/usr/share/sounds/ekiga/voicemail.wav', 'r') for i in range(w.getnframes()): frame = w.readframes(i) print frame As a result of this code I expected to see sound pressure as function of time. In contrast I see a lot of strange, mysterious symbols (which are not hexadecimal numbers). Can anybody, pleas, help me with that?
Per the documentation, scipy.io.wavfile.read(somefile) returns a tuple of two items: the first is the sampling rate in samples per second, the second is a numpy array with all the data read from the file: from scipy.io import wavfile samplerate, data = wavfile.read('./output/audio.wav')
