User Guide
ACM Waveform (.wav)
Microsoft ACM (Audio Compression Manager) is part of all 32-bit versions of Windows.
Adobe Audition supports the ACM driver, which enables you to open and save files in a
variety of formats other than those directly supported by Adobe Audition.
Some of these formats come as a standard part of Windows, while others are provided by
third-parties. You may acquire ACM formats when you install other software.
To save a file in an alternate format by using the ACM driver, choose File > Save As, choose
ACM Waveform as the file format, and click Options. You can select from among various
quality levels, and each level will give you different options for formats and attributes.
Note: The ACM driver you want to use might require that the file be in a specific format before
saving it. For example, if you want to save a file in the DSP Group TrueSpeech format, you
should first use the Edit > Convert Sample Type command to convert the file to 8 KHz, mono,
16-bit, because that is the only format that the TrueSpeech ACM driver supports. 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.
Amiga IFF-8SVX (.iff, .svx)
The Amiga IFF-8SVX format is an 8-bit mono format from the Commodore Amiga computer.
Options Choose from the following:
• Data Formatted As saves the audio file in uncompressed 8-bit Signed format (the
default setting) or in the compressed 4-bit Fibonacci Delta Encoded format.
• Dithering From 16-bit specifies a type of dithering for 16-bit files: Triangular Dither,
Shaped Gaussian Dither, Noise Shaping A, or Noise Shaping B. No Dithering is the default.
For more information on types of dithering, see “Changing the bit depth” on page 113.
Apple AIFF (.aif, .snd)
AIFF is Apple’s standard wave file format. AIFF supports mono or stereo files, 16-bit or
8-bit resolution, and a wide range of sample rates. Adobe Audition supports only the
PCM-encoded portion of the data, even though this format (like Windows WAV) can
contain any one of various data formats.
