Equalizer (Yellow) 167

Stereo Widener

Not an equalizer in the traditional sense, but it does use equalization to work its magic. By emphasizing certain
frequencies on one stereo channel, while attenuating them on the other, it creates a subtle stereo effect. This is done
symmetrically, so that when the signal is summed to mono, the effect is completely canceled out with no coloration
to the sound. The Stereo Widener works well with either mono or stereo source signals.
Use "Intensity" to control the impact to the sound. At higher values of "Intensity" you can actually drive the sound out
of phase; this is not a problem, however, as the sound still stays mono compatible.
With "Tune", you can tweak the effect to your taste by shifting the focus towards lower or higher frequencies.

Phase Widener

The Phase Widener is an effect invented by us. It creates a wide stereo signal from a mono signal without coloring
the outcome at all. Even when summed back to mono, no coloring will occur.

Delay Widener

This is the condensed version of the well-known stereo-widening trick of delaying one side of a stereo signal by
several milliseconds. In contrast to the Phase Widener, the Delay Widener is not mono-compatible and should be
checked for coloration when used on a recording. Additionally, the Delay Widener will tend to emphasize the non-
delayed side - this is a psychoacoustic artifact. Setting the Delay Widener to about 30 ms should give you a pleasing
result.
