Python: write a wav file into numpy float array
ifile = wave.open("input.wav")
how can I write this file into a numpy float array now?
Answer
>>> 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
