6 Do one of the following:
• Play back the session to record (or “lay-
back”) Pro Tools output to lower bit-rate
media (such as a DAT).
– or –
• Choose File > Bounce To > Disk. In the
Bounce to Disk dialog, select the appropri-
ate bit depth (such as 16-bit for CD audio).
Before being converted by the Bounce to
Disk
command, the signal is processed ac-
cording to the resolution and noise shap-
ing settings in the dither plug-in inserted
on the Master Fader.
Sample Rate Conversion and Bit Depth
Reduction
If you want to do both a sample rate conversion
and a bit depth reduction when mixing down,
first convert the sample rate while maintaining
the higher bit depth, and then reduce the sam-
ple rate-converted file to the lower bit depth, us-
ing a dither. By keeping the higher bit depth
when performing the sample rate conversion,
you ensure the highest possible audio quality.
Bus Recording to Tracks
You can create a submix in your Pro Tools ses-
sion and bus record it to available tracks in the
same session. This technique lets you add live
input to the mix, as well as adjust volume, pan,
mute, and other controls during the recording
process. You can also use this technique instead
of Bounce to Disk to create mixed tracks directly
in your Pro Tools session.
Voice Requirements
Recording a submix to new tracks requires an
available voice for each track that you want to
record. Make sure you have enough voices avail-
able to play back all tracks that you want to
record and enough voices available to record the
destination tracks.
In contrast, the Bounce to Disk command lets
you bounce all available voices to disk without
holding any in reserve, but you cannot manu-
ally change any controls during the bounce. For
more information, see “Bounce to Disk” on
page 962.
To record a submix to a track:
1 Apply any plug-ins or external processors you
want to add to your audio tracks or Auxiliary In-
puts before you record.
For information about Digidesign dither
plug-ins, refer to the DigiRack Plug-ins
Guide
.
For information about voice management,
see “Track Priority and Voice Assignment”
on page 182.
With Pro Tools HD, RTAS plug-ins placed
on Auxiliary Input, Master Fader, and In-
strument tracks will use additional voices
and may introduce extra latency based on
the H/W Buffer Size. For more information,
see “Voice Usage and Total Latency for
RTAS Plug-ins” on page 874.
