Python wavio

wavio is a simple library for reading wavfiles into numpy arrays, and converting them back into numpy arrays.

NOTE:

Personally, I found the private methods much more useful than the public interface.

Usage

import wavio

numpy_array = wavio.read('/var/tmp/audio.wav')

wavio.write(
    '/var/tmp/audio.wav',
    numpy_array,
    rate=44100,  # samplerate/framerate in Hz
)

wav_str = wavio._array2wav(numpy_array, sampwidth=2)
numpy_array = wavio._wav2array(nchannels=2, sampwidth=2, numpy_array)
