PyListen

A simple pyaudio microphone interface

PyListen abstracts creating an audio stream and converting raw byte data into numpy arrays.

Usage

from pylisten import Listener, WindowListener, FeatureListener

for chunk in Listener(frames_per_buffer=512, rate=24100):
    print('Current volume:', abs(chunk).mean())

for window in WindowListener(1024 * 10, 1024):
    print('Volume of last 10 chunks:', abs(window).mean())

for features in FeatureListener(lambda x: [abs(x).mean()], 1024, 20):
    print('Past 20 volumes:', features)

Installation

pip install pylisten
