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.
Wave files
Wave files have the extension “.wav” and are the most
common file format on the PC platform.
Wave files support the same options as AIFF files.
Insert Broadcast
Wave Chunk
(File Format
section)
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, turn off the option and re-export.
Edit button (File
Format section)
By clicking this button the “Broadcast Wave Chunk”
dialog opens where you can enter additional informa-
tion 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 au-
thor, description and reference that will automatically
be displayed in the “Broadcast Wave Chunk” dialog.
Outputs pop-up
menu (Audio
Engine Output
section)
This menu lists all output busses and channels in the
active project. Simply select the bus or channel you
want to mix down.
Mono Export
(Audio Engine
Output section)
If you activate this option, the exported audio is mixed
down to mono.
Split Channels
(Audio Engine
Output section)
Activate this option if you want to export all channels
as mono files.
Real-Time
Export (Audio
Engine Output
section)
If you activate this option, the export will happen in real
time, i.e. the process will take the same time as regular
playback. Some VST plug-ins require this in order to
have enough time to update correctly during the mix-
down – consult the plug-in manufacturers if uncertain.
Cubase: When Real-Time Export is activated, the ex-
ported audio will be played back via the Control Room.
Update Display
(Audio Engine
Output section)
If you activate this option, the meters will be updated
during the export process. This allows you to check for
clipping, for example.
Sample Rate
(Audio Engine
Output section)
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 qual-
ity (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
usage 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.
Option Description
Bit Depth
(Audio Engine
Output section)
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 rec-
ommend 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 manual
“Plug-in Reference” for details). This reduces the ef-
fects of quantization noise and artifacts from being in-
troduced 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.
Audition Volume
fader (Audio
Engine Output
section)
Cubase: The fader below the Real-Time Export check-
box allows you to adjust the Control Room volume.
Note that this fader is only available if the Control
Room is activated.
Pool (Import into
project section)
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 “Import Medium…” on page 279.
Audio Track
(Import into
project section)
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.
If this option is activated, the Import Options dialog ap-
pears on export. For a description of the available set-
tings, see “Import Medium…” on page 279.
Close dialog
after export
If this option is activated, the dialog will be closed after
the export, otherwise it will be left open.
