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,

Hi Conrad, Thanks a lot for the info. This is exactly what I needed. We want to use speex in our IP telephony client and I was indeed trying to put together a GUI configuration screen.

Hi, I've just released beta4, which will hopefully be the last beta before starting release candidates. There are a number of quality improvements and a some new features. First, the quality of variable bit-rate (VBR) has been greatly improved, mostly for wideband. Also, some improvements were made to the packet-loss concealment code in order to reduce artifacts caused by lost packets. There

Sorry, VAD is still float, but if you're using the built-in one, float emulation should work (it's not very compute-intensive).

Hi Marc, Thanks for your quick response. So if VAD is enabled then VBR will be enable although it's a special VBR. How about take out the VAD code from the VBR and remove the code else?

hi there, I am new to mailing list so excuse me if I don't obey to the 'netiquette'. i am writing voice chat and speex is in the root of it. i write it in Java and use JNI to link with 'C'-based Speex 1.2beta. [I know of JSpeex but there are not implemented some features] recently i decided to use DTX feature of speex as well. the code follows. The problem is that no matter

Hello, I'm try to run speex on some ARM processor. I'd like to cut away some speex features including VBR, ABR and preprocessor while still supporting VAD/DTX. But I've found some puzzles in the source code regarding VAD as below, 1) there are VAD related codes in the source file preprocess.c. Will VAD still work If I don't use the source file preprocess.c? 2)The speex manual

Hi, I'm updating speex support in sweep to RC2 and I'd like some advice on encoder options, and would appreciate some testing of the user interface. a screenshot of the updated speex encoding dialog: http://www.vergenet.net/~conrad/tmp/sw_speexRC2_1.png you can grab a tarball of sweep for testing here: http://www.vergenet.net/~conrad/tmp/sweep-0.8.0-speexRC2.tar.gz general

Hello. I am working on implementing RFC 5574 (RTP Payload Format for the Speex Codec) in the ffmpeg and have a question concerning it. It would be nice if somebody could answered it. * Chapter 4.1.1 Registration of Media Type Audio/Speex, subpart "Optional parameters" states these SDP optional parameters: vbr: variable bit-rate - either 'on', 'off', or 'vad'

Jesus, Unfortunately, FFT and magic algorithms don't work (yet?). You might want to try this if you're not satisfied with Speex VAD: http://lists.xiph.org/pipermail/speex-dev/2008-August/006860.html It won't perform any miracles, but I think it works pretty well and is easy to tweak.

Hello, in my project im using speex 1.2rc1 and the preprocessor VAD seems to only separate complete silence from not complete silence frames. The Speex Manual, you can read "The voice activity detector (VAD) provided by the preprocessor is more advanced than the one directly provided in the codec." but if you go to the source code in preprocess.c line 995 "/* FIXME: This VAD
