...rts 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 vom hawkvoice ( http://www.hawksoft.com/hawkvoice) and the result is quite favorable for hawkvoice. I cant believe that this is *normal* speex behavior, please correct me if that hawkvoice thing just performs better on that bandwidth. Now for my question: Could you please tell me what options are best for w...

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...

First, what do you mean by AVB (average bit-rate?)? Al...

...xamples 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. -----Original Message----- From: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org] On Behalf Of Peter Kirk Sent: Tuesday, May 13, 2003 11:55 AM To: speex-dev@xiph.org Subject: Re: [speex-dev] reommended settings for low bitrat...

Just curious, any reason you're not using Speex for high quality (at 18.2 and 24.6 kbps, I can't distinguish the coded from the original and 15 kbps is pretty close)? I'm also not sure I see the idea of narrowband PCM either, since you can get better quality at...

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 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 perceived voice quality and latency. Celp based codecs sound great when the tolerance range for the recording input is...
