Off-line processing 9 – 185
The Normalize controls
These are used to normalize the sound before and/or after processing.
Please note the following:
• The effect of all dynamic processing depends on the amplitude (level) of the mate-
rial to be processed. Therefore, if you process a number of files with slightly different
levels (for example using presets or batch processing) the effect of the processing
will be different from file to file. To avoid this, activate “Normalize before”.
• On the other hand if you are experimenting with different settings, this means that
after activating “Normalize before” you may have to re-adjust the Threshold level.
See “Level Normalizer” on page 178 for more information on normalizing.
• One reason for setting the “Normalize before” value to less than 0 dB (full level) is
if you are expanding, which might introduce clipping if the signal is too strong to
start with.
Again, click the question mark icon in the dialog for details.
The Dynamics controls
When the Graphic Editing switch is deactivated, the dynamics processor
works very much like a simple compressor. Use the Threshold and Ratio
settings to set the amount of compression (click the question mark icon in
the dialog for details).
About graphic editing
When the Graphic Editing check box is activated, you can specify any in-
put to output function. This allows you to “draw” limiters, noise gates, ex-
panders, etc. and combinations of all these. See the presets for examples.
• The curve shows input level along the horizontal axis and output level along the
vertical axis. With a straight line diagonally, each input level is represented by the
same output level (the signal is not processed at all).
