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

Without seeing some examples of your Speex implementation, it would be difficult to comment. I can tell you that you need to make that the conversion between floating point and fixed is done properly. This seems to be a common problem. Also, I am confident that TeamSpeak is using LHACM.ACM and distributing it. While HawkVoice is being distributed, it doesn't appear to be used at all.

Does anybody have useful tips on creating good quality recordings for use with prompts in asterisk? I'm interested in hearing input on hardware (mics, dats, sound cards, etc) and software (recording software, dsp) as well as recording techniques. Jerimiah Tularosa Communications

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

Hey folks, Running TeamSpeak while playing WoW, I'm having trouble keeping my microphone going for any length of time. It will work fine for a while, but then suddenly stop working altogether until I force-reload ALSA. The microphone is no longer listed as being available. As far as I can tell, this only happens with games in Wine, but I've only really tested it with WoW. Any idea

Hello Jean-Marc and all, I recently had a talk with somebody about CELP. He said, there is this federal standard 1016 (4.8kbps) with a reference implementation of the Department of Defense (only on Sun, unfortunately, if I got this right). This one is noticed in the manual already. He also said, since there is this implementation of the DoD, nobody would voluntarily re-implement CELP. If I read

Any clues where I can find rpms for this (on Centos 4.x), I have tried a number of different site with no luck. Many thanks Denis

Do es anyone know what the following means for sound under Wine? fixme:mixer:ALSA_MixerInit No master control found on MPU-401 UART, disabling mixer Severa of us are trying to get WOW internal voice chat and teamspeak to work (different uses - wow for groups, teamspeak for guild). Im wondering if the above output has a workaround until a fix is made or even if it's related to our partial

Wine requires direct access to sound device(s) to make sound. This is true for both ALSA and OSS driver back-ends. However most sound servers are not compatible with neither of these back-ends. This also true about pulse-audio - it is not fully compatible with Wine. If you using new distro (Fedora 8, Ubuntu 8.04, SuSE 11) and do not have sound you should: 1. Report problem to your distro support

Hello kind developers, I am planning on creating a steganographic extension for speex/CELP. Since speex/CELP is lossy, there should be quite many bits that one can use for hiding data. I'm familiar with the principles of CELP (two filter loops, one for pitch, the other for formants, let the raw speech frame run through those filter loops, take residue signal, map it on a codebook entry,

Hi, We would like to announce the first release of the Speex project. Speex (http://speex.sourceforge.net) is an open-source (LGPL), patent-free compression format allowing an alternative to expensive proprietary codecs. Unlike Ogg Vorbis which compresses general audio, Speex is designed especially for speech. For that reason, Speex is meant to be a complement to Vorbis. Since it is specialized

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

Lots of key words. Just generally, how well does Wine handle voice chat? Jim -------------- next part -------------- An HTML attachment was scrubbed... URL: http://www.winehq.org/pipermail/wine-users/attachments/20080312/1cc0255c/attachment.htm

Jean-Marc, I am building a tool for producing the highest possible quality Internet interviews for "podcasting" applications. The goal is to produce a perfect recording of an interview or conference -- and giving the participants a glitch-free experience is secondary. My approach, therefore, is to build a Windows "wave" file asynchronously by using a streaming

Hello I'm working about audio and video codecs. I'm making a research about the state-of-the-art in coding technologies. My question is about the speex codec 1.0. I would like to know the name of the algorithms that it uses.(LPC,CELP..). It uses more or less the same algorithm for narrowband and wideband? Finally i would like to ask about future codec developement projects. Thanks

Hello Jean-Marc: I've been watching the speex development from its inception because I and several Tech Startup Connection members have a very important application for this voice encoding/decoding. Further, we are quite familiar with ACELP as implemented in G.729. As far as I know Speex is also ACELP ... yes/no? Question ... what do you see as the advantages of ACELP compared to MP3? I

hi all, thanks Jean for the codec. I am new to speech coding. Am interested to implement speex on a TI dsp, say C54. just downloaded speex v 1.1.6. when I removed optimisation flags for win32 in libspeex.dsp, I get a slightly different output for decoding using speexdec.exe (debug version). no prob for speexenc.exe except for some differences in the ogg header. for anyone interested, i
