I want to choose one codec between iLBC and Speex,because the codec is run on the embedded system,so the performance is the key factor to be encode and decode to be a real system. so ,i like to ask which codec is better in perfomance on the same hardware system? thank you -------------- next part -------------- An HTML attachment was scrubbed...

In the current asterisk code, with the current (1.1.12) speex code, compiled for sse on x86_64, at a 2 quality setting, speex is now slightly faster than ilbc. that said, it's generally slower on most embedded arches On 5/8/06, he zhu <zhumrkk@gmail.com> wrote:> > I want to choose one codec between iLBC and Speex,because the codec is run > on the embedded system,so the performance is the key factor to be encode and > decode to be a real system. > > so ,i like to ask which codec is better in perfomance on the same hardware > system? > > thank you > > _______________________________________________ > Speex-dev mailing list > Speex-dev@xiph.org > http://lists.xiph.org/mailman/listinfo/speex-dev > > >-- Mike Taht PostCards From the Bleeding Edge http://the-edge.blogspot.com -------------- next part -------------- An HTML attachment was scrubbed...

If you want to check out the speed of Speex, I recommend you use the latest subversion version (which will soon go in the next release), which has significant speed improvements. Jean-Marc
