# Saving list of floats to audio file on disk

01-list-to-audio-file.py

This program generates 5 seconds of white noise with pure python function and saves the samples in a file called noise.aif on the Desktop.

    from pyo import savefile
    from random import uniform
    import os

    # Create the path for the audio file.
    home = os.path.expanduser("~")
    path = os.path.join(home, "Desktop", "noise.aif")

    # Audio file properties (sampling rate, duration and number of channels).
    sr = 44100
    dur = 5
    chnls = 2

    # Generate a list of `chnls` sub-lists with `sr * dur` floats in each of them.
    samples = [[uniform(-0.5, 0.5) for i in range(sr * dur)] for i in range(chnls)]

    # Save the list of floats in an audio file on disk.
    savefile(samples=samples, path=path, sr=sr, channels=chnls, fileformat=1, sampletype=1)
