A python module for importing wave (*.wav) files into numpy.
Contains a single module wavy providing the functions get_audio and slice_wave.
To read in a wavefile:
from wavy import get_audio
audio = get_audio('soundfile.wav')To read in the third second of the file:
from wavy import get_audio
audio = get_audio('soundfile.wav', offset=2, duration=1)To save the third second of the file to a new file:
from wavy import slice_wave
slice_wav('soundfile.wav', 'second.wav', offset=2, duration=1)To down sample an audio file, specify the max_framerate argument in either
get_audio or slice_wave. The audio will be
subsampled so that the resulting framerate is less than or equal to max_framerate.
For example, to ensure that the framerate is less than or equal to 4k:
from wavy import slice_wave
slice_wav('soundfile.wav', 'subsampled.wav', max_framerate=4000)This was developed for a specific project, and is put here in case other people find it useful. It hasn't been tested on a wide variety of files. If you find that it doesn't work as expected, carry out the usual pull request business.
