AC: This emulates the constant, low hum of AC
current.
Frequency switch: This sets the frequency of the AC
current (50 or 60 Hz), and thus the pitch of the AC hum.
Timeline: This dial regulates the amount of overall
effect. The farther to the right (1900) you turn this dial,
the more noticeable the effect.
Karaoke
Apply this effect to clips such as mp3 songs or audio
CD tracks to remove the main vocal from the
performance. What remains – the accompaniment – can
be used as background music, or as the backing for
your own vocal in a voice-over or video clip.
The Karaoke effect depends on the fact that the main
vocal part in a recording is usually divided about
equally between the two stereo channels. The plug-in
digitally compares the channels and removes the
common part from both. Not all recordings are well
suited for karaoke use.
Volume: This slider lets you adjust for variations in the
total output volume that may be introduced by Karaoke
processing. Move the slider towards the left if the audio
is too loud with the filter applied, or towards the right if
it is too soft.
