By opening audio data as PCM, you can interpret almost any audio file format—but make sure that you have some
idea about the sample rate, number of channels, and so on. You can also interpret the data as A-law or mu-law
compressed.Whenyouguessattheseparametersuponopeningafile,itmaysoundincorrect(dependingonwhich
parameters are wrong). Once the file is opened and sounds fine, you may hear clicks at the start or end of the
waveform, or sometimes throughout. These clicks are various header information being interpreted as waveform
material. Just cut these out, and you’ve read in a wave in an unknown format.
Choose from the following options:
Data Formatted As Specifies the format of the saved data.
When Opening, Offset Input Data By Specifies the number of bytes by which to offset the input data.
Create .DAT Header File On Save Writes a header to a separate .dat file to make reopening the file easier.

About video file formats
Adobe Audition lets you import and export video files in AVI, MOV, or WMV format. When you export to video,
you must save in the format of the video file you imported in the session. For example, if you import an AVI file, you
can export to video only in AVI format.

Uncompressed AVI (.avi)
AVI (Audio Video Interleaved) is a multimedia file format for storing sound and moving pictures on Windows
systems. AVI is a container format, meaning that it specifies how data is organized, but it is not itself a form of audio
or video compression.
Uncompressed AVI is a good alternative to DV AVI or other compression schemes because there is no loss of data
on exporting.
DV AVI (.avi)
DV AVI format includes the DV codec compression scheme. This Windows format is primarily used to exchange
sound and video with a DV camera through a Firewire (IEEE 1394) port.
QuickTime (.mov)
The QuickTime file format is used to create, edit, publish, and view multimedia files. QuickTime supports many
different types of compression. Like AVI, QuickTime AVI is a container format, meaning that it specifies how data
is organized, but it is not itself a form of audio or video compression.
Although Apple Computer, Inc. developed this format, its use is not limited to Mac OS. However, Windows users
must install QuickTime for Windows to work with QuickTime files.
