Python: write a wav file into numpy float array

Question

ifile = wave.open("input.wav")

how can I write this file into a numpy float array now?

Answer 1

>>> from scipy.io.wavfile import read
>>> a = read("adios.wav")
>>> numpy.array(a[1],dtype=float)
array([ 128.,  128.,  128., ...,  128.,  128.,  128.])

Typically it would be bytes which are then ints... here we just convert it to float type.
