Detailed Description

An Effect that modifies volume in different frequency bands.

Performs filtering, using an FFT to do a FIR filter. It lets the user draw an arbitrary envelope (using the same envelope editing code that is used to edit the track's amplitude envelope).

Also allows the curve to be specified with a series of 'graphic EQ' sliders.

The filter is applied using overlap/add of Hann windows.

Clone of the FFT Filter effect, no longer part of Audacity.
