Detailed Description

An Effect for removing clicks.

Clicks are identified as small regions of high amplitude compared to the surrounding chunk of sound. Anything sufficiently tall compared to a large (2048 sample) window around it, and sufficiently narrow, is considered to be a click.

The structure was largely stolen from Domonic Mazzoni's NoiseRemoval module, and reworked for the NEW effect.

This file is intended to become part of Audacity. You may modify and/or distribute it under the same terms as Audacity itself.
