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.
