Hi all,
This should please all those who want to know more about Speex or
Vorbis. Monty and I have just finished writing this paper: "Improved
Noise Weighting in CELP Coding of Speech - Applying the Vorbis
Psychoacoustic Model To Speex" which you can get at:
http://people.xiph.org/~jm/papers/aes120_speex_vorbis.pdf
It's probably the best description of the Speex encoder to data and it
has a lot of details about the Vorbis psycho-acoustic model. For those
who actually want to try the improvement described in the paper, just
configure Speex with --enable-vorbis-psy .
Jean-Marc
P.S. This will be presented at the next AES convention in Paris (May).
