- ISO-MPEG Audio Layer 3 software only Encoder and Decoder for Unix
- Version 2.00.
-
- copyright Fraunhofer - IIS 1994, 1995
-
- - evaluate highest quality perceptual audio compression technique
- available today
- - software only encoder and decoder implementations
- - implements ISO/MPEG Audio standard ISO/IEC IS 11172-3, Layer 3
- - wide range of compression ratios including
- 6:1 fully transparent quality
- 11:1 64 kbps per channel, very high quality
- 16:1 still better than your average 16 bit 44.1 kHz sound card
- - music data is input in raw format (16 bit signed integer), in
- RIFF/WAVE format as used by Microsoft Windows .WAV files, in
- AIFF/AIFC format as used by SGI and Mac or in .snd/.au format used
- by NeXT and Sun.
- - 44.1kHz sampling frequency (32 kHz and 48 kHz also for registered users)
- - packed bit stream conforming to ISO/MPEG Layer III
- - output of decoder is in raw format (16 bit signed integer),
- in .snd/.au format, in AIFF/AIFC format or in RIFF/WAVE format
- - .WAV music files can be played with Windows Media Player
- - Under rare circumstances the .WAV output is broken. Please use raw format
- in that cases.
- - optional decoder output as 24 bit hex ascii data
- - written by the very same people at Fraunhofer-IIS who did the
- Layer III codecs for the ISO and ITU-R (former CCIR) tests
- (best sound quality at low bit rates at all listening tests)
- - commercial real time products for encoding and/or decoding of
- Layer III are available. Contact one of the companies listed
- in the file info.txt
