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 and
have one additional option:
• Don’t Use Wave Extensible Format
The Wave Extensible format contains additional metadata, such as the
speaker configuration. It is an extension to the normal Wave format that
some applications may not be able to handle.
If you get problems using the Wave file in another application, activate
this option and re-export.
Broadcast Wave files
Concerning audio, Broadcast Wave files are the same as
regular Wave files, but without compression. To create a
Broadcast Wave file, select Wave as the file format and ac-
tivate the Insert Broadcast Wave Chunk option. Click Edit if
you wish to edit the chunk information, otherwise the de-
faults as specified in the Preferences (Record–Audio–
Broadcast Wave page) will be used. Broadcast Wave files
have the extension “.wav”.
Broadcast Wave files support the same options as regular
Wave files.
Edit button By clicking this button the “Broadcast Wave Chunk” dia-
log 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, description
and reference that will automatically be displayed in the
“Broadcast Wave Chunk” dialog.
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 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, without
adding to audio quality. Also consider the future usage of
the file – if you e.g. plan to import the file into another ap-
plication, 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 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 AI, we re-
commend that you select the 32 bit (float) option.
32 bit (float) is a very high resolution (the same resolution
as used internally for audio processing in Cubase AI),
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 dithering, see “Dithering” on
page 89.
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.
Mono Export If you activate this option, the exported audio is mixed
down to mono.
Split Channels Activate this option if you want to export the two chan-
nels of a stereo bus as separate mono files.
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.
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
151.
Option Description
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 151.
Close Dialog
after Export
If this option is activated, the dialog will be closed after
the export, otherwise it will be left open.
