hi,<br>i am using AVTransmit3.java for transmitting audio,<br>how can i implement JSpeex or speex for compression and encoding.<br>please give me some idea about this.<br><br>shankar.s<br><br><b><i>speex-dev-request@xiph.org</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Send Speex-dev mailing list submissions to<br> speex-dev@xiph.org<br><br>To subscribe or unsubscribe via the World Wide Web, visit<br> http://lists.xiph.org/mailman/listinfo/speex-dev<br>or, via email, send a message with subject or body 'help' to<br> speex-dev-request@xiph.org<br><br>You can reach the person managing the list at<br> speex-dev-owner@xiph.org<br><br>When replying, please edit your Subject line so it is more specific<br>than "Re: Contents of Speex-dev digest..."<br><br><br>Today's Topics:<br><br> 1. problem decoding file (Damien Guiserix)<br> 2.

speex-dev@xiph.org<br>Message-ID: <886-49183@sneakemail.com><br><br>I have been using the Speex NB mode with an 11025 kHz signal, without adjusting the framesize, and it's been sounding just fine to me. However I was wondering what the best way to make 11025kHz would be. I also have an audio driver that uses 2kB buffers, and the NB framesize of 160 doesn't divide evenly into that so I end up having to shovel tails of buffers around which isn't too efficient.<br><br>So I wondered if there was a clean way I could change the NB mode buffer size to be 256, which would be a little closer 20ms at 11025 but also be divisible by 2048.<br><br>Should I add a new custom mode to the modes array or should I mess with the NB mode? Any advice on what I should do with subFrameSize and the other parameters in SpeexNBMode (if anything) if I change the framesize to be
256?<br><br>Thanks,<br>Dave<br><br><br>------------------------------<br><br>_______________________________________________<br>Speex-dev mailing list<br>Speex-dev@xiph.org<br>http://lists.xiph.org/mailman/listinfo/speex-dev<br><br><br>End of Speex-dev Digest, Vol 35, Issue 24<br>*****************************************<br></damienguiserix@gmail.com></jean-marc.valin@usherbrooke.ca></damienguiserix@gmail.com></jean-marc.valin@usherbrooke.ca></jean-marc.valin@usherbrooke.ca></damienguiserix@gmail.com></damienguiserix@gmail.com></jean-marc.valin@usherbrooke.ca></damienguiserix@gmail.com></blockquote><br><p>
