With GET CLIP LEVEL the CLIP LEVEL can be gaged automatically.
The interpolated signal peaks adjust the whole level, which must be balanced
out with the GAIN fader so as to avoid new overmodulation. When doing so,
you should observe the peak meter to the right of the dialog.
The option "LIMITER" switches on a limiter which reliably avoids
overmodulation.
With the INVERSE button you can control whether or not undistorted parts of
the wanted signal are interpreted as clippings and are filtered out
unnecessarily.
Dehisser
The Dehisser was especially designed to eliminate the band noise, which is all
so typical for analogue tape recordings, micro-preamps or AD-transducers.
Noise Level: Here you will have to determine as exactly as possible the noise
level at which the Dehisser starts to work. If you choose a level that is not high
enough, the band noise will not be completely eliminated. In such a case you
will notice tweeting sounds (the so called "melodic band noise"). An excessive
value will result in a dull sound as part of the band noise and part of the
original audio signal recording will be eliminated by the Dehisser as well (for
example: air intake sounds of brass instruments) (see Artifacts (view page 80))
If
the noise level on your recording is low, you should experience no problems
while adjusting it.
Adaptive: The value for the noise level parameter is set automatically by
determining the hiss contained in the signal. If the noise level value is
changed, its effect is then relative, i.e. the resulting value is determined from
the automation as well as the noise level fader settings.
One advantage is that you no longer have to set the noise level value manually
and that this value can also be adjusted later if the noise share fluctuates, for
example, if you use music tracks with differing hiss levels within one project.
If the noise level is constant, a better result may be obtained manually
(Adaptive off). However, the noise level value must then be set precisely.
