...'dtx_enable' flag in it, so the decoder on the other end knows it's in dtx mode? (and SPEEX_GET_DTX_STATUS returns 1) At the moment, I can hack around it by doing something like: if (VAD for prev frame && ! VAD for this frame) { iArg = 0; speex_encoder_ctl(m_esEncState,SPEEX_SET_VBR, &iArg); speex_encoder_ctl(m_esEncState,SPEEX_SET_QUALITY, &iArg); SBEncState *sbe = static_cast<SBEncState *>(m_esEncState); EncState *es = static_cast<EncState *>(sbe->st_low); es->dtx_count = 1; } (in wideband) .. which forces speex to send the DTX packet...

...and the problem is that, if I use a mumble client that tries to reproduce a wave file containing a 1Khz tone, I cannot hear that tone. I've tried to comment all the denoise functions but nothing could solve the problem. I've turned off the VBR, with the function speex_encoder_ctl and the SPEEX_SET_VBR define but the result is that I can here the tone for 1-2 seconds and then noise, terrible noise. Can someone help me, please ? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

I have two questions: 1. ?I would like to enable VBR with the Speex codec for VoIP communications. Is this setting made within VoIP clients themselves or is it a setting that must be changed on the specific version of Speex (for example, via command line)? 2. If not, is there any way to create RTP packets via the Speex command line? (The goal is to view the lengths of the packets created by
