Github: https://github.com/ARanch/audiotimer

This small program starts listening for an audio input on the system microphone. When a set audio level threshold is reached, a timer is started. When the audio level is reduced below the threshold, the timer is stopped after a short countdown, and the timespan is logged.

python -m pip install audiotimer

install requirements: pip install -r requirements.txt

Note: on Mac OS you need Portaudio installed, otherwise you will get the error ERROR: Failed building wheel for PyAudio. Install it using: brew install portaudio before installing requirements.

run using: python -m audiotimer

see -h flag for run-time options.

Eample usage: Run using a treshold of "50" and a buffertime of 30 seconds: python -m audiotimer -t 50 -b 30

Use case

The program is intended to be used as a way of testing the battery life of battery powered loudspeakers. Set the speaker to play a pink noise at a certain level, and leave a laptop with the speaker to listen for when it dies out.
