Basic usage

Below is a basic example showing how to reduce the speed of a wav file by half using the phase vocoder procedure:

from audiotsm2 import phasevocoder
from audiotsm2.io.wav import WavReader, WavWriter

with WavReader(input_filename) as reader:
    with WavWriter(output_filename, reader.channels, reader.samplerate) as writer:
        phasevocoder(reader.channels, speed=0.5).run(reader, writer)
