Thank you, but I am thinking about trying to move VAD implementation from 1.1.12 to 1.2. I'm not sure about how difficult it could be (maybe impossible due to Jean Marc has disappear).

...k (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.

Hi Cecile, it seems it is a tabu theme, or nobody uses VAD on speex. I've tried with external EasyVAD solution but the result was not as spected. Other users of the list suggest an algorithm to filter voice based on the power of the signal, but of course, it is not a voice activity detection. I am waiting also a solution for this, while so I use version 1.1.12. Regards. Cecile Dumotier

...ode/protocol to make sure you're decoding exactly the data that the encoder produced. You might be surprised at the result. Also keep in mind that the nature of the audio data itself may be triggering the problem, especially if it is unusual in some way.

I think there is a problem. If we are coding PCM 16 mono, then, when we decode the samples we should obtain PCM 16 mono again, but wave data over 16bits is extracted from the decoder. If the input level is reduced we could loss wave information. Thanks for your help <p>Jean-Marc Valin wrote: >> we are using speex 1.0.3 under windows. We code samples with

Hi! I'm developping a Win32 application for VoIP purposes. Until now, we are using speex 1.0.x and it works fine, but when we begin to use 1.1.x, audio starts to be corrupted after some minutes of use. We use M$ Visual Studio 2002 Any idea? Thanks.

hello everybody, i've download the new 1.2beta1, and compile it with VC++ 6.0, at this point, all ok. i get the libspeex.lib and when i link it to my project (that was using speex 1.1.12) it reports an error: "unresolved external symbol lpc_window" this symbol is defined in window.c and its referenced in sb_celp.c and nc_celp.c, but im not sure if im doing something wrong or

Hello, first of all, sorry for the joke in the subject ;-) I have successfully update the speex library my software was using from 1.1.12 to 1.2beta1 (1.1.13). It is a VoIP software, where i set preprocessor VAD on and use the result of speex_preprocess() to determine if there is voice activity. I must say that it works fine...since i have update to the new version. Ive been testing, and

Hello, i'm adding echo cancellation to my voip application, but when i call speex_echo_capture() or speex_echo_playback() causes an assertion failed, it seens that there is a delete in any where. i've encapsulated echo canceller in a class that storage the state and simply call the functions: void EchoCanceller::Playback(short *echo_frame) { speex_echo_playback(echo_state,

Hi, when I use preprocessor with AEC, VC++ alerts me about heap corruption. I have protected speex_echo_playback, speex_echo_capture and speex_preprocess_run with mutexes, to avoid echo_state being used at the same time, but it still happens. Any help about this ussue? Thank you.

Hello, im using speex library on my vo ip project, but some times, after it works ok, it begins to play noises (like voice hits) decoding the packets of one source (the others sound ok). I finally found that reseting SpeexBits and decoder state it solves. If i cant avoid this problem, i wish to solve when it occours, but ?how to detect this? Please, if anyone has experiment this issue i

Hello, we are using speex 1.0.3 under windows. We code samples with values from -32.000 to 32.000 (signed short), but when we decode these samples the values range from -45.000 to 45.000. What is the problem? <p> Thanks --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message

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
