codec at very low bit rate (2 kbps)
I'm not sure, but I think that Microsoft have the license now.. anyone know if there is the source code to download? Or others codecs.. thank you very much ---------- Original Message ---------------------------------- From: "John Miles" <jmiles@pop.net> Date: Mon, 19 Jun 2006 10:15:59 -0700 >Do a search on "Voxware MetaVoice".

Integer Version with low bit rate for Linux Kernel?
Hello, I am looking for a speech codec with low bitrate, 2000 (desired) to 2400 (max) bps. It should run in c code within the LINUX Kernel, fully integer based. Is this possible with speex?

low data rate codecs
Hi, I've been testing out the speex narrowband codec at low data rates (using linphone and Counterpath's Eyebeam). I'm finding that at data rates of ~25 kbps, the quality of the voice call is very poor. I know speex is supposed to work at much lower data rates (~2 kbps). Has anyone verified that speex will produce reasonable quality at low data rates? Are there any existing

Speex codec for 8Kbps setting ?
Hi, I am looking how to setup speex codec in codecs.conf for 8 Kbps and 6 Kbps. In config file are many parameters for setting. I don't know what is need to change for narrowbad like 8 Kbps and 6 kbps. Any suggestion? [speex] ;0-10 quality => 4 ;0-10 complexity => 4 ; true / false enhancement => true ; true / false vad => false ; true / false vbr => false ; 0 = off, otherwise,

Trouble about the interpretation of intercept in lm models
Hallo, yesterday I was puzzled when I discovered that I probabliy miss something in the interepretation of intercept in two-way lm models. I thought that the intercept, using the default contr.treatment contrasts, represents the mean of the group of observations having zero in all column of the model.matrix. It turns out not to be case To be more more clear I am attaching a short example:

Is there an oggenc low bit rate HOWTO?
First let me say that I was absolutely astounded at the sound quality when using oggenc at q = -1 (around 50 kbps). So much so, that I'm anxious to try some of the lower bit rates that were mentioned in the announcement for 1.0: ... audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. But I am having trouble finding how to use either oggdrop or oggenc to get these

low sampling rate
Hello, is somebody working on a good low-sampling rate / low-bitrate mode? I encoded today a mono/16KHz/16bit WAV (a TV-talkshow), using OggDrop. The quality of the '64kbps' mode was unacceptable, so I had to use '80kbps' mode. The bitrate averages around 42 kbps, which I found a bit high for this quality. In your opinion, what bitrate should I expect as Vorbis matures? 24 kbps?

reommended settings for low bitrate voicecom codec ?
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

Low bit rate codec (speex)
Hello, I've read about speex's bit rate. Speex can work from 2.15kbps to 44.2kbps. With asterisk, what's the bit rate used by speex? Is it possible to have asterisk using speex at less than 10kbps of bit rate? If not, Is it dificult to implement? thanks in advance Eduardo

Why Point-Stereo at 160 kbps ?
Hi there ! I checked Vorbis' performace for mono files at approx. 64-80 kbps (it does a good job) and I'm wondering why the current OggEnc still uses Point-Stereo (>10kHz) for -q4 and -q5 I know, we're usually unable to percieve those phase correlations above 10 kHz, But a Dolby Prologic Decoder isn't. I think a future version of OggEnc which is able to use a user-selectable

I am very happy to announce that the aoTuV tuning of Ogg Vorbis has tied with Musepack at first place in the 128 kbps listening test. It has beat iTunes AAC, Lame MP3, ATRAC3, and WMA standard. :) http://www.rjamorim.com/test/multiformat128/results.html -- ------------------------------------------------- Stephen So PhD Student Signal Processing Laboratory School of Microelectronic

winamp bitrate (kbps) display wrong
I have noticed that when playing OGGs in Winamp, the bitrate displayed is always much higher than the average bitrate of the file. This was using the plugin that comes with Winamp v2.80 (v1.2 b7) For example, the latest oggenc encoded a song to 77kbps - I verified that this matched the filesize correctly. Apart from the first and last few seconds of the song, Winamp always displays between 85 -
