Wave File Formats Supported by Adobe Audition
ACM Waveform (.wav):
Nearly any file format supported by the Microsoft Audio Compression Manager (ACM) can be loaded or saved in Adobe
Audition. The available ACM formats are displayed in the Choose ACM Format dialog that appears when you press the
Options… button on the Save Waveform As dialog.
Note: The ACM driver you want to use may require that the file be in a specific format before saving. For example, if you want
to save a file in the DSP Group TrueSpeech format, you should first use Edit > Convert Sample Type to convert the file to
8KHz/mono/16-bit, because that’s the only format supported by the TrueSpeech ACM driver. For more information on any
particular ACM driver, contact the creator of the format (such as DSP Group for TrueSpeech, or CCITT for the various
CCITT formats) or the manufacturer of the hardware that uses the format in question.
Options Set the following:
• Name displays the name of any saved format presets. Three are provided initially: CD, Radio, and Telephone Quality.
• Save As: Click this button to save additional preset format/attribute combinations.
• Filter is the ACM format you wish to save in. Note that this list will display only those formats that are compatible with
the current waveform’s properties (stereo/mono, resolution, etc.).
• Attributes: The available attributes will depend on the original attributes of the file (sample rate, etc.) and the Filter
chosen.
• Write as RAW Data: Check this box to save the waveform as RAW data.
Amiga IFF-8SVX (.iff, .svx)
The Amiga 8SVX format is an 8-bit mono format from the Commodore Amiga computer. A variety of sample rates are
supported.
Options Choose from the following:
• Data Formatted As 8-bit Signed: Check this option to save the audio file in uncompressed 8-bit Signed format, which
is the default.
• Data Formatted As 4-bit Fibonacci Delta Encoded: With this selection made, the file will be saved using the
compressed 4-bit Fibonacci Delta encoded format.
• Dithering from 16-bit: If you’re saving from a 16-bit file, choose the type of dithering you wish: Triangular Dither,
Shaped Gaussian Dither, Noise Shaping A, or Noise Shaping B. No Dithering is the default.
Apple AIFF (.aif, .snd)
This is Apple’s standard wave file format. Like Windows WAV, AIFF files support mono or stereo, 16-bit or 8-bit, and a
wide range of sample rates. Adobe Audition only supports the PCM encoded portion of the data, even though this format
(like Windows WAV) can contain any one of a number of data formats.
