LEAD Audio Detection Filter (2.0)

This filter determines whether there is sound or silence. The filter uses a threshold: signal levels above this threshold are considered sound and levels below this threshold are considered silence.

Notifications are passed via a user callback.

The filter has both user and programming interfaces.
