About 18 months ago I had asked on this list how to make a
requested stereo widener plug-in effect. I recently came across the
plug-in I had started, and finished it. Thanks to David Walsh and
Monty for their input back in 2004.
A stereo widener creates the illusion that your speakers are
further apart than they really are. Stereo widening results depend
on distance of your speakers from each other, the plug-in settings,
and your location in relation to the speakers.
This stereo widener works by inverting both left and right channels
of stereo audio to some degree, then panning those inverted signals
somewhere between the center pan position and the opposite channel.
A time offset of up to 20ms can be applied to enhance the illusion.
copy widener.ny into your Audacity plug-ins folder. Next time you
re-start Audacity, you'll find Stereo Widener under the effects
1. Inverted signal volume
