hi, I have this problem in my app, and even when the VAD does work, it doesn't do good job on noisy enviroment. It would be nice feature to have VAD support on pjsip to reduce bandwidth and help with voice quality. I am using AMR vocoder with VAS and on reception of compressed AMR frame i decode it back to PCM, compute the energy and make decision based on the energy. not so sofisticate VAD algo but works fine. nir On Tue, Jul 28, 2009 at 11:55 AM, Fabio Pietrosanti (naif) < lists at infosecurity.ch> wrote: > Hi all, > > as not all you know, not all Nokia S60 devices support AMR's encoding with > VAD features and some of them does not support it in proper way. > > It could be nice whether we could arrange a distributed testing activity > with a sample application that test the AMR VAD behaviour, in order to > create a knowledge base on device UID that works properly and devices that > does not work properly where VAD must be disabled. > > Fabio > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > -- ??? ?????? ??: 050-3930056 nir.elkayam at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
