WAVELAB
9 – 182 Off-line processing
Attempts/Analysis –
Desired precision
If the Desired loudness requires peak limiting, this will also reduce the
loudness to some degree. This can’t be computed in advance and be
automatically applied to the gain change, because the limiting is a com-
plex process. Instead, several simulation passes are performed to find
the best possible gain. This option lets you define the desired precision
of the result.
Attempts/Analysis –
Maximum number of
passes
WaveLab will perform as many analysis passes as are needed to match
the desired precision. Use this option to specify the maximum number
of passes to be performed.
Attempts/Analysis –
Authorized peak
compression
As too much compression will degrade the audio quality, you can here
specify a limit to the applied compression. The value can be set be-
tween -1 and -20 dB. If you actually need maximum allowed compres-
sion (-20 dB) to achieve the desired loudness, it might be better to
reconsider, and instead lower the Desired loudness value, as this will
almost certainly render better results.
Warn if
unmatched
If checked, this will warn you if the normalizing process does not meet
the desired loudness/precision. This option is not available in the Batch
processor.
Statistics This opens a window which shows you information about the file to be
processed. It will show any DC offset, the current loudness, the current
peak level, the required gain to achieve the desired loudness, and an in-
dication about whether or not limiting is required.
Loudness
distribution
This opens the Loudness distribution dialog where you can see how
frequently a given loudness occurs in an audio file. For instance if the
peak in the display is at -12 dB, this would be the most frequent loud-
ness found in the file (this is different from average loudness). Use the
“?” button in the dialog for more information.
