Wave File Formats Supported by Adobe Audition
As it saves a .cel file, Adobe Audition calculates how much silence is going to be added to the MP3 file and writes this
information into the .cel header. Then, when Adobe Audition loads a .cel file, it reads this silence information and
automatically removes the silence from the file so that it'll loop smoothly.
The file saving options are identical to the ones for mp3PRO® (.mp3) files, which are documented later in this
Options
chapter.

Creative Sound Blaster (.voc)

This is the Sound Blaster and Sound Blaster Pro voice file format. Adobe Audition supports both old and new style .voc
files. The older .voc format only supports 8-bit audio; mono to 44.1 kHz, and stereo to 22 kHz. The newer type of .voc
file supports both 8-bit and 16-bit audio.
VOC files can contain information for looping and silence. If the file you're loading contains loops and silence blocks,
they'll be expanded while loading.
Choose one of the following:
Options
Old Style saves your audio as an 8-bit .voc file that can be played on any Sound Blaster card.
•
New Style allows you to save to the newer .voc format that supports both 8-bit and 16-bit audio.
•

Dialogic ADPCM (.vox)

The Dialogic ADPCM format is commonly found in telephony applications, and has been optimized for low sample rate
voice. It will only save mono 16-bit audio, and like other ADPCM formats, it compresses to 4-bits/sample (for a 4:1
ratio). This format has no header, so any file format with the extension .vox will be assumed to be in this format. When
opening VOX files, you'll be prompted for a sample rate unless Don't ask for further details is checked in the Open a
Waveform dialog.
Note: Take note of the sample rate of your audio before saving as Dialogic VOX, as you'll need to enter it upon reopening the
file.

DiamondWare Digitized (.dwd)

This is the audio format used by DiamondWare's Sound Toolkit, a programmer's library that lets you quickly and easily
add high quality interactive audio to games and multimedia applications. It supports both mono and stereo files at a
variety of resolutions and sample rates. See http://www.dw.com for more information.
