New Audio File Formats
New Features in SONAR 7
format supported natively in Mac OS X, and is also used by QuickTime
7. Audio in Core Audio Format files can be uncompressed PCM or
compressed (such as AAC).
Note: 24-bit AIFF and Next/Sun files are imported as 32-bit floating point
files. This is a lossless conversion.
See Importing Audio CD Tracks.
New Export Formats
• Sony Wave64 (*.w64)—The Sony Wave64 file format is similar to the
RIFF format, but is a true 64-bit file format designed to overcome the
size limitations of the RIFF format.
For more information, see Sony Wave-64 Support.
• Apple AIFF (*.aif)—Audio Interchange File Format, co-developed by
Apple Inc., is most commonly used on Apple Macintosh computer
systems.
• NeXT/Sun (*.au)—Au is the standard audio file format used by Sun,
Unix and Java. The audio in au files can be 8-bit or 16-bit PCM or
compressed with the µLaw, alaw or G729 codecs.
• FLAC (*.flac)—FLAC stands for Free Lossless Audio Codec, which is
somewhat similar to MP3, but lossless. Audio in a FLAC file is
compressed without any loss in quality.
• Sound Designer II (*.sd2)—Sound Designer II is the native format of
DigiDesign’s Sound Designer pro audio software and is also used
natively by Macromedia DECK II and many applications. SD2 files can
be mono or interleaved stereo.
• Core Audio Format (*.caf)—Core Audio Format is a new 64-bit audio
format supported natively in Mac OS X, and is also used by QuickTime
7. Audio in Core Audio Format files can be uncompressed PCM or
compressed (such as AAC).
• RAW (*.raw)—Rarely used, a RAW file can contain audio in any codec
but is usually used with PCM audio data.

Encoding Options
After clicking the Export button, an additional dialog will appear showing
Extra Encoding Options. These options typically determine the bit depth,
endian-ness (the byte ordering in memory used to represent the data), and
an encoding type within the major file format.
