Stereo FX
The "Stereo FX" enhancer lets you edit the justification of the audio
material in the stereo panorama. If stereo recordings sound
unfocused and undifferentiated, an extension of the stereo base-
width can often provide a better transparency.
Base width controller: Adjusts the base width between mono (on the
extreme left), unchanged base width (center), and maximum base
width (”wide”, on the extreme right). Reducing the base width can
produce a rise in the level. In extreme cases – when the left and right
channels include identical material and the base width controller is
pushed to the left on ”mono” – the result can be a level rise of
3 decibels.
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.
