To Bounce to Disk:
1
Choose File > Bounce to > Disk.
2
Select any mono or stereo output or bus path
as the source for the bounce.
3
Select the File Type (such as WAV), Format
(such as mono or stereo), Resolution (such as 16-
bit), and Sample Rate (such as 44.1 kHz).
4
If you are changing the sample rate of the
bounced file, choose a Conversion Quality set-
ting.
5
Click Bounce.
Using Dither on Mixdown
You should use a dither plug-in whenever you
are bouncing or mixing down audio to a lower
bit depth (for example, when mastering a 24-bit
session to 16-bit resolution for release on an au-
dio CD.)
If you are bouncing or mixing down audio for
reuse at the same bit depth (for example, for
transfer from one 24-bit capable system to an-
other), you do not need to dither the output.
It is preferable to use Master Faders instead of
Auxiliary Inputs for applying dither, because
Master Fader inserts are post-fader. With a Mas-
ter Fader, any changes to the track’s Volume
fader will be processed by the dither plug-in.
To dither audio for mixdown:
1
Create a Master Fader and assign it to control
the output path for the audio you want to mix
down or bounce.
2
Insert the included DigiRack Dither plug-in
(or another dither plug-in) on the Master Fader,
after any other plug-ins or inserts on the track.
3
In the dither plug-in window, click the Bit Res-
olution button and select the destination bit
depth (20-bit or 16-bit).
4
In the dither plug-in window, click the Noise
Shaping button and select a Noise Shaping set-
ting. Type 1 is appropriate for mono files, and
Type 2 or Type 3 are appropriate for stereo files.
5
Choose File > Bounce to Disk to perform the
mixdown.
Sample Rate Conversion on Mixdown
When you specify a different sample rate for a
bounced file (for example, when mixing down a
session recorded at 48 kHz to 44.1 kHz for re-
lease on an audio CD), a Conversion Quality set-
ting becomes available in the Bounce to Disk di-
alog.
There are five possible Conversion Quality set-
tings, ranging from Low (lowest quality) to
TweakHead (highest quality). The higher the
quality of sample rate conversion, the longer it
takes to convert the bounced file.
To create a mixdown that can be written to
an audio CD, be sure to select WAV, stereo
interleaved, 16-bit, 44.1 kHz.

sample rate conversion when mixing down,
