SYNOPSISaifcdecompress [-verbose] infile.aifc outfile.aifc
DESCRIPTIONaifcdecompress is a command-line program which reads an AIFF-C compressed
digital audio input file, and copies the header information and sample
data to a AIFF-C uncompressed digital audio output file.
The output file will contain copies of all the AIFF-C chunks in the
original input file. The chunks may not appear in exactly the same order
as in the original file.
aifcdecompress decodes data which has been compressed using one of the
algorithms supported by the SGI audio file library:
G.722 CCITT G.722 ADPCM 4:1 compression recommended for 16-kHz, 16-bit
mono or stereo data. The compression algorithm currently cannot
handle more than two channels.
mu-law CCITT G.711 mu-law 2:1 compression recommended for 8-kHz, 16-bit
(mono or multichannel) data.
A-law CCITT G.711 A-law 2:1 compression recommended for 8-kHz, 16-bit
(mono or multichannel) data.
Aware MPEG
MPEG I layer 1 or 2 audio compression implemented by Aware, Inc.
for 32, 44.1, or 48 kHz mono or stereo 16-bit data.
Aware MultiRate
Aware proprietary MultiRate near-lossless or lossless audio
compression. for mono or stereo 16-bit data at any rate.
If the input AIFF-C file parses correctly, and the output file is written
with no errors, aifcdecompress returns 0. If there is an error,
aifcdecompress returns 1.

If invoked with no arguments, aifcdecompress displays help.
If the verbose option is specified, aifcdecompress periodically prints
messages as sample data is copied from the input file to the output file.
The AIFF and AIFF-C file format specifications are published by Apple
