Export Audio Mixdown
AIFC files
AIFC stands for Audio Interchange File Format Com-
pressed, a standard defined by Apple Inc. These files sup-
port compression ratios as high as 6:1 and contain tags in
the header. AIFC files have the extension “.aifc” and are
used on most computer platforms.
AIFC files support the same options as AIFF files.
Insert Broadcast
Wave Chunk
This allows you to include information about the date
and time of creation, a timecode position (allowing you
to insert exported audio at the correct position in other
projects, etc.) along with author, description and refer-
ence text strings in the exported file.
Some applications may not be able to handle files with
embedded info – if you get problems using the file in
another application, deactivate the option and re-export.
Edit button By clicking this button the “Broadcast Wave Chunk” di-
alog opens where you can enter additional information
that will be embedded in the exported files. Note that in
the Preferences (Record–Audio–Broadcast Wave
page) you can enter default text strings for author, de-
scription and reference that will automatically be dis-
played in the “Broadcast Wave Chunk” dialog.
Don’t Use Wave
Extensible
Format (Wave
files only)
The Wave Extensible format contains additional meta-
data, such as the speaker configuration. It is an exten-
sion to the normal Wave format that some applications
may not be able to handle.
If you get problems using the Wave file in another appli-
cation, activate this option and re-export.
Insert iXML
chunk
This allows you to include additional project-based or
sound metadata (e.g. scene and take information) in the
exported file.
Some applications may not be able to handle files with
embedded info – if you get problems using the file in
another application, deactivate the option and re-export.
Sample Rate
(only uncom-
pressed file for-
mats)
This setting determines the frequency range of the ex-
ported audio – the lower the sample rate, the lower the
highest audible frequency in the audio. In most cases,
you should select the sample rate set for the project,
since a lower sample rate will degrade the audio quality
(mainly reducing the high frequency content) and a
higher sample rate will only increase the file size, with-
out adding to audio quality. Also consider the future us-
age of the file – if you e.g. plan to import the file into
another application, you should select a sample rate
supported by that application.
If you are making a mixdown for CD burning, you should
select 44.100 kHz, since this is the sample rate used on
audio CDs.
Bit Depth (only
uncompressed
file formats)
Allows you to select 8, 16, 24 bit or 32 bit (float) files. If
the file is an “intermediate mixdown” that you plan to re-
import and continue working on in Cubase, we recom-
mend that you select the 32 bit (float) option.
32 bit (float) is a very high resolution (the same resolu-
tion as used internally for audio processing in Cubase),
and the audio files will be twice the size of 16 bit files.
If you are making a mixdown for CD burning, you should
use the 16 bit option, as CD audio is always 16 bit.
In this case, we recommend that you activate the UV-
22HR dithering plug-in (see the separate PDF document
“Plug-in Reference” for details). This reduces the effects
of quantization noise and artifacts from being introduced
when converting the audio down to 16 bit.
8 bit resolution should only be used if required, since it
will result in limited audio quality. 8 bit audio may be
suitable in some multimedia applications, etc.
Option Description
Realtime Export If you activate this option, the export will happen in real-
time, i.e. the process will generally take the same time
as regular playback. Some VST plug-ins, external instru-
ments and effects require this in order to have enough
time to update correctly during the mixdown – consult
the plug-in documentation.
Cubase only: When Realtime Export is activated, the ex-
ported audio will be played back via the Control Room.
Update Display If you activate this option, the meters will be updated
during the export process. This allows you to check for
clipping, for example.
Mono Export
(only for single-
channel export)
If you activate this option, the exported audio is mixed
down to mono.
Split Channels Activate this option if you want to export all sub-chan-
nels of a multi-channel output bus as mono files.
Pool Activate this option if you want to import the resulting
audio file automatically back into the Pool. A clip refer-
ring to the file will appear in the Pool.
If this option is activated, the Import Options dialog ap-
pears on export. For a description of the available set-
tings, see “About the Import Medium dialog” on page
268.
Audio Track If you activate this option, an audio event that plays the
clip will be created and placed on a new audio track,
starting at the left locator.
Furthermore, the Import Options dialog appears on ex-
port. For a description of the available settings, see
“About the Import Medium dialog” on page 268.
Create New
Project (uncom-
pressed file for-
mats only)
Activate this option if you want to automatically create a
new project that contains one audio track for each ex-
ported channel. The tracks will have the corresponding
mixdown file as audio event. The track names will be
identical with the export channel names.
Note that the new project will be the active project.
Close dialog
after export
If this option is activated, the dialog will be closed after
the export, otherwise it will be left open.
Audition Volume
fader (only for
single-channel
export)
Cubase only: During a Realtime Export, this fader is dis-
played in the progress dialog after you clicked the Ex-
port button. It allows you to adjust the Control Room
volume. Note that this fader is only available if the Con-
trol Room is activated.
