Collect data from microphone

This node will send data as soon as the microphone volume is higher than a threshold.

This is using python Sounddevice.

It detects beginning and ending of voice activity within a stream of audio and returns the parts that contains activity.

There's a maximum amount of voice duration, to avoid having no input for too long.
