between different songs,
the function "Normalize loudness" is also provided in
the "Effects" menu.
DeEsser: These special presets serve to remove overly present "s" sounds in
voice recordings.
Stereo FX
The Stereo FX enhancer allows you to determine the positioning of the audio
material in the stereo picture. If the stereo recordings sound out of focus and
undifferentiated, an extension of the stereo base width can often provide better
transparency.
Bandwidth control: Adjusts the bandwidth between mono (on the extreme
left), unchanged bandwidth (center), and maximum bandwidth (”wide”, on the
extreme right). Reducing the bandwidth can produce a rise in the level. In
extreme cases, e.g. when the left and the right channels include identical
material and the bandwidth control is pushed to the extreme left on “mono”,
the result can increase the level by 3 dB.
Raising the bandwidth (values of 100) diminishes the mono compatibility. This
means that recordings edited this way sound hollow when listened to in mono.

Volume control: Adjusts the volume of every single channel, thereby adjusting
the entire balance. The reduction of left and right levels is displayed under the
control buttons. A centered recording can later be moved to the left or right of
the stereo balance.
Stereo meter: This provides a graphic display of the phase relation of the audio
signal. You can use it to review the orientation of the signal in the stereo
balance and the effect of the stereo enhancer.
In order to achieve greatest compatibility with mono, the display should come
closest to a diagonal line. Otherwise some frequency ranges may erase
themselves if the stereo signal is played on a mono device.
Karaoke presets: These presets open 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.
