Export a surround mix
Adobe Audition can export surround mixes in either one WMA or WAV file that contains all six channels, or six
separate WAV files for each channel.
Note: If you plan to deliver exported files to an outside service for surround encoding, confirm format requirements with
that service.
1 Click Export at the bottom right of the Surround Encoder dialog box.
2 In the Multichannel Session Name box, enter a filename prefix for the exported files.
At the bottom of the dialog box, the Filenames To Be Saved section displays the complete filenames.
Complete filenames appear at the bottom of the dialog box.
3 In the Save In box, specify the folder for the saved files.
4 From the Format options menu, select one of the following:
Export As Six Individual Mono Wave Files Creates mono Windows PCM (.wav) files that can be used by any
Windows audio application.
Export As One Interleaved, 6-Channel Wave File Creates a single, six-channel file in Windows PCM (.wav) format.
However, some Windows audio applications support only mono and stereo WAV files.
Note: InterleavedfilesreflectthechannelorderusedbyDolby®Digitalencoders.Ifyouplantouseanencodingprocess
with a different channel order, export the session as six individual files, instead.
Export And Encode As Windows Media Audio Pro 6-Channel File Creates a multichannel WMA file that can be
played by anyone who has Windows Media Player 9 or later, a multichannel output sound card, and a 5.1 speaker
setup. Set the following Windows Media Audio options:
• Constant Bit Rate (CBR) Varies the quality level as needed to ensure that the bit rate stays the same. This method
makes a consistently sized file, although the quality may not be as high as with Variable Bit Rate encoding.
• Variable Bit Rate (VBR) Maintains the audio quality by varying the bit rate depending on the complexity of the
audio passage being encoded. This method can maintain higher quality audio in the file, although the file size is not
as predictable as with Constant Bit Rate encoding
• Lossless Compresses to a smaller file size than WAV, but results in no fidelity loss.
• Fold Down To Stereo Settings Determine how the surround mix will sound on a stereo system. Specify attenu-
ation levels to mix the Center, Surround, and LFE channels with the front stereo channels. The defaults are good
settings for most files, but you can enter custom values between 0 and –144 dB.
