Common Audio Formats files
Common Audio Formats overview
The Common Audio Formats setting makes it easy to create audio files in the following formats:
•
AIFF: The Audio Interchange File Format (AIFF) was developed by Apple for storing high-
quality audio. The format was intended for DVD or CD authoring and is now one of the most
commonly used audio file formats for the Mac OS.
Note: Use the Common Audio Formats setting to create standard AIFF files. If you need to
create specialized AIFF format files, choose the AIFF option from the File Format pop-up menu.
•
Apple CAF: The Apple Core Audio Format (CAF), developed by Apple, provides high
performance and flexibility and is scalable to future ultra-high-resolution audio recording,
editing, and playback. It has an unrestricted file size and supports a wide variety of metadata.
•
WAVE: The Waveform audio file format (WAVE) is primarily used on Windows computers.
