Export Audio Mixdown
The Export Audio Mixdown dialog
About the Audio Engine Output section
The Audio Engine Output section contains all the settings related to the output of the
Cubase audio engine. The following options are available:
Option Description
Sample Rate
(uncompressed file
formats only)
This setting determines the frequency range of the exported 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 plan to import the file
into another application, for example, 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
(uncompressed file
formats only)
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 recommend 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), and the audio files will
be twice the size of 16 bit files.
If you are making a mixdown for CD burning, use the 16 bit option,
as CD audio is always 16 bit.
In this case, we recommend dithering, see “Dithering” on page 233.
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 results in limited audio quality. 8
bit audio may be suitable in some multimedia applications, etc.
Mono Downmix In Cubase Artist, activate this f you want to downmix the two
channels of a stereo bus to a single mono file. In Cubase, activate
this if you want to downmix all the subchannels of a stereo or
surround channel or bus to a single mono file. To avoid clipping,
the following summing rules are applies:
Stereo: The panning law as defined in the Project Setup dialog is
applied (see
“Stereo Pan Law” on page 187). Surround (Cubase
only): The channels are summed and then divided through the
number of channels used (in case of a 5.1. channel =
(L+R+C+LFE+Ls+Rs)/6).
Split Channels Activate this if you want to export all subchannels of a multi-
channel bus as separate mono files.
L/R Channels Activate this if you want to export only the left and right
subchannels of a multi-channel bus into a stereo file.
