I Mpeg audio Layer 2 & 3 encoder port under OpenVMS                Oct 1997 1 =================================================   N The source kit contains ISO mpeg original audio encoder and decoder. Only the K encoder is ported under OpenVMS, an optimised decoder ported under OpenVMS  2 and working in real-time on Alpha already exists :  B  http://www2.cenaath.cena.dgac.fr/ftp/decwindows/mpeg3play-096.zip1  ftp://ftp2.cnam.fr/decwindows/mpeg3play-096.zip)   O You can find the encoder sources , object and executables files for VAX & Alpha L into [.LSF.ENCODER] directory. This encoder is Mpeg-1 Layer II and layer IIIM capable. However, it is not optimised and you need a fast cpu especially with 
 layer III.  O You can compress at bitrates as low as 128 kbs before really earing artifacts,  M even with Layer II !! At such a bitrate, the resulting Mpeg file of a 44 Khz  K 16 bits stereo stream is 30% smaller than a mono 8 bits 22 Khz WAV file and  gives a far better quality.    Patrick Moreau pmoreau@cena.dgac.fr moreau_p@decus.fr 
