The controls
To find out exactly what each control in the dialog does,
click the question mark icon in the dialog.
Gain Change
This also allows you to change the amplitude (volume) of
the selection, just like the Level Normalizer. The difference
here is that the gain change is set in absolute numbers,
plus/minus the current level (which is indicated as 0dB).
Clipping
This processor lets you do something that most other
functions in WaveLab Studio never do: introduce clipping.
Clipping is when the gain is raised to a point where distor-
tion is added. While this is normally not wanted, mild clip-
ping in for example the attack of a drum sound can add
some “punch”.
Loudness Normalizer
This processing tool allows you to specify the loudness of
a file. Because it relates to loudness as opposed to maxi-
mum peak level, this tool works quite differently than the
Level Normalizer. A typical application is to specify a level,
e.g. -12dB, and the Loudness Normalizer will process the
loudness to match this level.
Like Gain Change, increasing the loudness to a certain
value might introduce clipping, which is to be avoided. To
remedy this, a peak limiter (the Peak Master plug-in) can
be part of the process. The Loudness Normalizer will
smartly raise the loudness and limit peaks in the signal at
the same time (if needed), to achieve the desired loud-
ness.
In case of stereo files, both channels are processed inde-
pendently.
• This process happens over two stages; first an analysis
and then the final rendering.
The results of this analysis can be seen in the Statistics. If all seems well,
you can apply the processing using the Render button.
• The Loudness Normalizer is also available in the Batch
processor, which is logical as one of the primary applica-
tions is to process different files to equal loudness.
If you try to raise the
level of a wave above
0dB (100%)…
…it will get distorted
(the peaks are
“clipped”).
