l3enc is an ISO/MPEG Layer-3 software only encoder and decoder. It takes
audio data files as input and delivers Layer-3 coded bitstream files as
output. Several options can be selected via command line switches.
Usage: l3enc [-switch1 [-switch2 [...]]]
Features
- 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 and ISO/IEC IS-13818-3, Layer 3
- 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 (8, 11.025, 12, 16, 32 kHz and 48 kHz also for registered users)
- 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 3 codecs for the ISO and ITU-R (former CCIR) tests (best sound quality at low bit rates at all listening tests)
l3dec is an ISO/MPEG Layer 3 software only decoder. It takes Layer 3
bitstream files as input and delivers PCM audio data files as output. A
number of options can be selected via command line switches.
Usage: l3dec [-switch1 [switch2 [...]]]
