BOUNCE TO DISK
932
Supported fixed bit depths include 8, 16 or 24 bit
integer. You can also choose 32 bit Floating Point, if
the format you’ve chosen (Figure 84-2) supports
this resolution. If not, this menu choice is grayed
out.
Choose Project Default to use the current project
sample format. If you choose 8 bits (a sample
format not supported by Digital Performer for
playback), the Import option below will force you
to choose the Do not import setting.
Supported resolutions
8-bit resolution it typically applied to audio that
will be used in multimedia and internet
applications because it significantly reduces the
size of the audio files, halving the bandwidth
required to deliver the sound. When you are
bouncing down to 8-bit audio, you may want to
apply Digital Performer’s MasterWorks
Compressor (or a third-party dynamics plug-in of
your choice) to the mix to counteract the effect of
halving the dynamic range that results from going
to 8 bits.
16-bit resolution is the standard resolution for
compact disc audio.
24-bit audio provides greater resolution and
headroom and is used by many mastering systems.
32-bit floating point audio file resolution is an
emerging standard used for high-end recording,
mixing and mastering applications. Digital
Performer’s mix engine employs 32-bit floating
point precision throughout, as do other advanced
digital audio workstation systems. If you plan to
use the bounced material with Digital Performer or
another system that supports 32-bit floating point
processing, this option is a good way to preserve
and carry over the floating point precision
employed by these systems.
Import
The Import menu (Figure 84-1) lets you choose
what to do with the audio files generated by the
bounce operation. If you choose Do not import, the
file will be created on the hard drive but it will not
be imported into Digital Performer. Otherwise,
you can import the audio file into the Soundbites
window or into the current sequence as a new
audio track. If you have chosen a format not
supported by Digital Performer, you will not be
allowed to choose either of these import options.
Source
The Source menu (Figure 84-1) displays all output
and bus bundles currently defined in the Digital
Performer project (see chapter 14, “Bundles”). Use
the Source menu to indicate the output or bus
bundle that you wish to capture in the bounce. All
tracks that are currently selected and routed to —
or bussed to — the source bundle you choose will
be included in the bounce operation.
File name
In the File Name field (Figure 84-1), type in the
desired name for the resulting audio files. If
multiple files are generated (due to a deinterleaved
stereo or surround bounce operation), appropriate
extensions will be appended to the end of each file
name to indicate its channel (“.L”, “.R”, etc.)
Saving bounce settings
The Save Settings for Bounce Again check box
(Figure 84-1) lets you save the current bounce
settings. When you check this box, the Settings
Name and Key Binding options become available
(ungrayed), as shown in Figure 84-5. Type in a
name and (optionally) enter a custom key binding.
