Designer II, sometimes seen abbreviated as SD2) is a monophonic/stereophonic
audio file format, originally developed by Digidesign for their Macintosh-based
recording/editing products. It is the successor to the original monophonic Sound
Designer I audio file format.
An SDII file can be monophonic or stereophonic. When stereo is used, the
tracks are interleaved (sample-001-left, sample-001-right, sample-002-left,
sample-002-right, etc.) Files also store sample rate and bit depth information.
The SDII file has become a widely accepted standard for transferring audio
files between editing applications. Most Mac CD-ROM writer software, for example,
specifies SDII or Audio Interchange File Format as the file format needed when
making audio CDs.
The SDII file has also become accepted among personal computer audio application
developers. This makes transferring audio from Mac to PC platforms much easier.
When used on a PC, the file must use the extension of ".sd2".
To convert SD2 files to other audio formats, please make sure Apple QuickTime
Short for Audio
Interchange File Format, a common format for storing and transmitting sampled
sound. The format was developed by Apple Computer and is the standard audio
format for Macintosh computers. It is
also used by Silicon Graphics Incorporated
The AIFF format is uncompressed so AIFF files tend to be large. However,
there is another format called AIFF-Compressed (AIFF-C or AIFC) that supports
compression ratios as high as 6:1.
AIFF files generally end with an .AIF or .IEF extension.
AIFC files generally end with an .AIFC extension.
AIFF and AIFC are standard audio format used on MacOS systems. AIFF is not
compressed. AIFC is compressed.
To encode AIF audio, please make sure Apple QuickTime is
