DITHER
For an explanation of what dither is, see “Changing
bit depth with dither” on page 57 in the DP Plug-in
Guide.
Digital Performer’s mixing and processing engine
employs 32-bit resolution. When 16-bit or 24-bit
digital audio first enters Digital Performer, its bit
depth (resolution) is raised to 32-bits. From then
on, as the audio is mixed and processed, it remains
at 32 bits until it leaves Digital Performer. The
Dither command, when checked, makes Digital
Performer use dither whenever it must reduce the
bit depth of audio. For example, if you bounce your
mix to disk as a 16-bit, 44.1 kHz AIFF audio file to
later burn a CD, Digital Performer converts your
mix, which internally is being processed in 32 bits,
to 16 bits during the bounce operation. If the
Dither command is checked, dither is employed to
help reduce the inherent quantization distortion
that occurs when audio bit resolution is reduced.
FADE
The Fade command lets you create fades and
crossfades at the boundaries of soundbites to
eliminate undesirable artifacts. For complete
details, see “Fades and Crossfades” on page 633.
DELETE FADES
See “Deleting fades” on page 639.
FREEZE/UNFREEZE SELECTED TRACKS
The Freeze Selected Tracks command can be
thought of as a “mini”, temporary bounce: it
creates a new audio track, with the same output as
the original track, that contains a record pass of the
entire original track, complete with all real-time
effects rendered to the track. You can then disable
the original track, and its real-time effects plug-ins
or virtual instruments, to conserve computer
power. For details, see “Freezing tracks” on
page 144.
MERGE SOUNDBITES
Use Merge Soundbites to quickly create a single,
new soundbite out of several adjacent soundbites.
To do so, select the adjacent soundbites and choose
Merge Soundbites from the Audio menu. This
operation creates a new audio file, sort of like a
“mini-bounce”. But it does not include any
volume, pan or other automation data. It is meant
for joining audio regions on a small, local scale.
If you use the Merge Soundbites command when
there is a time range selection that extends beyond
the selected soundbites, the resulting soundbite
extends to the beginning and end of the selection.
STRIP SILENCE
Strip Silence breaks up a soundbite into several
smaller soundbites by removing all of the portions
that consist of silence.
Figure 49-1: Strip Silence.
For example, you can use Strip Silence to remove
the silence between words to separate them.
To use Strip Silence:
1 Click the soundbite in the Sequence Editor or
Event List to select it.
