Without clipping, the sound would now be a bit jumpy and restless, because sudden peaks would still be very loud for a very short moment. Also, the output volume would not be very constant yet. Fixing this makes the sound more pleasant to listen to, and more constant. The default settings already take care of this, but some changes may be necessary.
This step can usually be skipped: Clipping is turned on by default, and the default values usually perform very well.
If you are using low values for the down speed divider (decay), sudden peaks in the input
signal may still be heard as "clicks". Also, the output volume is probably not very constant.
To solve this, clipping can be used.
Note that the effects described here were probably already hidden because clipping is by default
turned on. Turn it off to hear the difference.
The clipping values can be set using the clipping sliders. These sliders control at which
peak volume clipping starts to occur. The values are relative with regards to the soft limit
(amplitude threshold) settings - 1.0 means that clipping starts as soon as this soft limit
value is reached.
Excessive clipping can introduce artifacts. Because of that, it's usually better to use slightly
higher values, such as 1.50. This ensures that peaks are not removed completely (which can also make
the sound a bit more flat), while very loud peaks (that would cause clicking sounds) are removed.
The amount of clipping that occurs is displayed as black bars in the output bars. If none are present,
the clipping could just as well be turned off. If a lot of clipping occurs, chances are that also
artifacts are generated, and it could be wise to increase the clipping value (or increase the
down speed divider (decay) for the frequency where excessive clipping occurs).
