Raising the base width (values over 100) diminishes the mono compatibility.
This means that recordings edited this way sound hollow when listened to in
mono.
Volume controller: Adjusts the volume of every single channel, thereby
adjusting the entire panorama. The damping of left and right levels is displayed
in dB underneath the controllers. A centered recording can later be moved to
the left or right of the stereo picture.
Stereo meter: This provides a graphical display of the phase relation of the
audio signal. You can use it to review the justification of the signal in the stereo
panorama and the effect of the stereo enhancer.
In order to achieve the greatest possible compatibility with mono, the display
should come closest to a diagonal line. Otherwise some frequency ranges may
cancel each other out if the stereo signal is played on a mono device.
Karaoke preset: This preset opens a special karaoke effect that more or less
eliminates vocals. It deletes middle frequencies typical for human vocals during
playback so that someone else can do the singing.
Invert phase
The sample data is inverted along the amplitude axis, which means that
negative values become positive and vice versa. This function allows you to
adjust recordings with different phases to one another.
An incorrect phase occurs if during an analog recording parallel cables are
switched. To correct such errors, some mixers have a switch that can be used
to invert the phase of an input. If you press the switch by mistake, errors might
occur as well.
This function is reversible, so if you repeat it, the original signal is restored.
Modulation / Special
Vocoder
The vocoder principle: Carrier material (e.g. a surface sound or a synth chord)
is affected by a modulator (e.g. language or singing) so that one gets the
impression that it is speaking or singing. Rhythmic surface sounds can also be
developed if modulated with a drum loop.
This is done via the transmission of the frequency characteristics of the
modulator (speech) on the carrier (chord).
