88200 You may want to work at a sample rate of
88.2 kHz if the final delivery will be at 44.1 kHz
(such as compact disc). This will provide a
slightly faster sample rate conversion to
44.1 kHz than from 96 kHz.
48000 This is a standard sample rate for Profes-
sional and DVD video, and is supported by DA-
88/98, DAT, and ADAT decks.
44100 This is the standard sample rate for com-
pact discs (CD), and is supported by DA-88/98,
DAT, and ADAT decks.
Custom For a custom sample rate, click in the
sample rate window and manually enter in a
value.
Pull-up and Pull-down Rates All available sample
rates support pull-up and pull-down rates, or
other specialized rates.
Sample Rate Conversion Quality
Option
The Conversion Quality option sets the quality
of sample rate conversion used to create the
converted file. The higher the quality of sample
rate conversion, the longer it takes to convert
the file after the bounce has taken place. There
are five possible settings, ranging from Low to
Tweak Head. For most applications, the Better
setting yields satisfactory results.
Processing Resources and Conversion Quality
Because the Best and Tweak Head settings take
longer than the others, you may want to use
them only in cases where the highest fidelity is
essential and you are not facing strict time limi-
tations.
Use Squeezer
The Use Squeezer option uses a proprietary DSP
algorithm specifically designed for performing
8-bit conversion of simple source files such as
voice-overs. It optimizes the dynamics of the au-
dio by preprocessing it using compression, lim-
iting, and gating before conversion to 8-bit res-
olution. This results in greater apparent
loudness in the signal, and improved intelligi-
bility. If you are converting a more complex 16-
bit audio file to 8-bit resolution, test this option
before converting all of your material.
Convert During or After Bounce
The Bounce dialog can perform any conversion
options, including sample rate and bit depth
conversion, during a bounce or post-bounce.
Convert During Bounce This option may take less
time than Convert After Bounce, but does so at
the expense of plug-in automation playback ac-
curacy.
Convert After Bounce The Convert After Bounce
option, though it takes more time, offers the
highest level of plug-in automation accuracy
possible.
Import Into Session After Bounce
The Import Into Session After Bounce option au-
tomatically imports the newly bounced files
into the Audio Regions List so you can place
them in tracks. If your newly bounced files are
split stereo files, they are listed together in the
Audio Regions List.
