soundmodular

soundmodular is a library of functions designed to perform real-time signal processing on blocks of audio. Each function takes inputs and outputs in a similar fashion, hence allowing them to be aggregated into a signal chain to imitate modular synthesis.

soundmodular is put together as two classes:

• Patcher
• Module

Example

Create a python file and paste this code. Ensure dependencies are available and installed. It should output a sequence of sounds upon running.

from soundmodular import Patcher
from pyaudio import paInt16

options = {
    'format': paInt16,
    'channels': 2,
    'sampling_rate': 22000,
    'save_file': 'testfile.wav'
}

patcher = Patcher(options)
module = patcher.module
T = 0.3                 # Time in seconds

noise = module.wnoise(0.7*T, 0.2*T, 0.6)

for n in range(2,6):
    filt = module.filterbank_22k(noise, n, 1)
    patcher.to_master(filt, 0.5, 0.5)

osc = module.osc_tone(T, 440)
patcher.to_master(osc, 0.5, 0.5)

patcher.terminate()

options contains parameters necessary to setup the PyAudio and wave instances. soundmodular offers a limited API to these libraries.
