...ryone, I'm a student at the Universtiy of Delaware, and will be soon starting some research on the effects of lossy audio compression on speech sounds. I will be preforming test with both mp3 and vorbis. First of all, if I use the '--ogg' switch to lame, does lame use GPSYCHO to encode the wave, or some other psychoacoustic model (perhaps one designed for the vorbis algorith)? Along these lines, I'm unable to get lame-3.89 and libvorbis rc2 to play nicely together. The lame build breaks when compiling ogg support (this is probably a known bug, so I'm not post...

I wonder what psycho-acoustic model is used in ogg vorbis. Did they create their own model (this requires big listening tests) ? Or is it something that was already there, like gpsycho ? <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

Hi, We are working on Oggvorbis encoder porting on embedded platform. Where can we find good test vectors (wav files) for testing OggVorbis encoder? Does anybody have any idea. Parul Embedded Engineer Einfochips Ltd

Hi, I think that it would be a good thing to know more about those 2 projects (and also the future patent free format). I think that many people as me know about Lame, but not about Vorbis, and vice-versa. It would be fine that someone (perhaps the maintainer) of every project would introduce to both group of people those projects. 2 things would be interesting (to my mind): - to know about the

Hi all, Is there a standard set of wave files for testing the quality of the output of oggenc?
