2 When the cursor changes to a chain icon, release the Fade length handle. Hold Option
to prevent reactivation of the automatic fade.
Note: If you move the region to a position where it doesn’t overlap another region, and
then move the corresponding Fade length handle to the zero position, the automatic
fade function is reactivated.
To adjust an existing fade
µ
You can adjust fade-ins and fade-outs by dragging the fade handles of the region envelope.
By default, the fade curve is linear, which means that the level increases evenly (linearly)
for the duration of the fade. Alter the fade curve to increase the level more quickly or
slowly as the fade progresses.
Note: You can also edit your fades numerically in the Fade tab of the Inspector. For further
information, see
Viewing Region Info in the Inspector .
Normalizing Regions
Typically, you want the volume level of your audio regions to be as high as possible,
without causing clipping. Changing the level of a region to the maximum possible
value—without causing clipping—is known as normalizing.
When a region is normalized, it is boosted so that the signal peak reaches (but doesn’t
exceed) the set digital level (maximum: 0 dB, but see below). All other portions of the
region are boosted by the same amount, so that the original dynamic range of the
recording is maintained. This ensures that the region will play at maximum level, without
clipping.
Tip: You should not choose 0 dB in the Normalize dialog, as this may result in clipping if
you increase the gain of the overall signal afterward—with an EQ, for example. A further
issue is that many CD players clip signals that reach 0 dB. As a good rule of thumb, you
should leave at least 3 to 6 dB of “headroom” to allow for further audio processing tasks,
such as mixing and effects processing.
To normalize regions
1 Select the regions in the Regions list or Wave View area.
2 Choose Region > Normalize Region.
