In my experience most of the jitter related issues are because people are using too small of audio buffer sizes that match the framing size of Speex - particularly in Windows. This isn't a problem with Speex, but as a programmer you should collect and append a few frames to match the size of your output audio frame buffer before attempting to play the sound. -----Original Message----- From:

The Speex ACM codec has been released as version 1.0.1.1. Enjoy! Here is a list of changes: * A setup application has been added to the release. Just click SETUP.EXE and follow the instructions. * The crash under Windows 95/98/ME was fixed. * A reported crash in VirtualDub, CDEx and possibly other applications was fixed * The codec's Format Tag was changed to an official Microsoft

Hi all, <p>i have send a mail to the jabber mailing list and ask them how to send speex data with the jabber instant messaging protocol. I have added the mail adter this one. If someone here has any experience with jabber and speex please let me know. Thanks, <p><p>Carsten Breuer ====================================================== Hi all, im new on this list, so i want to

Hello, the voice-communication TeamSpeak (www.teamspeak.org) is currently testing a version that supports speex codecs. The quality for high bitrates is quite good. BUT, the low-bandwidth speex codecs that are currently used arent very good. What I did to find this out: I comprared a speex AVB with 6.3 KBit/sec (total, overhead for packets and stuff included) and the 6.3 Kbit/sec Celp Codec

...iginal header by John Villar and included the 1.0 release items and update the Delphi header to the 1.0 release along with building a DLL. If you would like these items, I would be happy to send them to you. Other people were fairly helpful to me - so its my turn to share. Just send an email to adrennan@wiredred.com and let me know. PS: not sure this will be in reply to the poster as I just joined the list - so I apologize in the advance. <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list,...

I just finished testing and integrating Speex into our test project. Speex works excellent and sounds great for the bitrate. I have noticed, however, on cheaper microphones that Speex will produce loud static noise at high harmonics/amplitude in the sound. Is there some setting to prevent this static? I don't have this problem with various other manufacturer voice coders that I am using

Speaking of video conferencing in conjunction with Speex, we are currently beta testing a solution we developed that offers multi-point, multi-party video and audio using the Speex engine for voice. http://www.wiredred.com/downloads/ecsetup.exe The fair and good audio settings are Speex narrowband, high quality is HawkVoice and toll quality is PCM. -----Original Message----- From:

Hello Jean-Marc, Regarding your question - a little background on the various choices, Fair Quality is 15kbps Speex narrowband, Good Quality is 24kbps Speex narrowband, High Quality is 32kbps ADPCM from HawkVoice and Toll Quality is 64kbps PCM. We also have 10 other codecs within the product including GSM, LPC and others that we currently do not expose. To us, quality is a combination of

I tend to disagree. It normal human conversation it wouldn't make much sense to have 2 people talking over each other at the same time. Thus, it most scenarios you would have only one talker anyway. Additionally, encode->decode/mix/encode->decode isn't a very efficient CPU process for a server, it's complicated to keep timing correct and it has a negative impact on total

Hello, HawkVoice doesn't have a 6.3kbps codec for CELP, it has a 4.5kbps CELP codec and I do not believe it is being used by TeamSpeak. The 6.4kbps CELP being used in TeamSpeak, to which you are referring I believe comes from Lernout & Hauspie's LHACM.ACM file which it appears you are redistributing (I assume TeamSpeak has a license and permission to do this). The only people I
