soundit

A small library for audio manipulation.

import soundit as s
s.play_output_chunks(s.chunked(s.exact(1, s.sine(440))))

Installation

Simply run:

$ pip install soundit[sounddevice]

The [sounddevice] extra installs sounddevice for playing audio through speakers.

Usage

A longer example:

import itertools
import soundit as s

indices = s.make_indices_dict()
frequencies = s.make_frequencies_dict()
notes = "a3 c e a g e c e d e d c a3 c a3 g3".split()

s.play_output_chunks(s.chunked(itertools.chain.from_iterable(
    s.exact(0.5, s.sine(frequencies[indices[note]]))
    for note in notes
)))

An even longer example:

import soundit as s
s.init_piano()  # See its documentation for details on its setup

names = "do di re ri mi fa fi so si la li ti".split()
indices = s.make_indices_dict(names)
music = '''
    . mi mi mi
    fa do . do
    . so mi do
    re mi,re - mi
'''

s.play_output_chunks(s.chunked(
    s.volume(2, s._notes_to_sound(
        s.music_to_notes(music, line_length=1.15),
        lambda name, length: s.piano(indices[name] + 1),
    ))
))
