Delays estimation in Speex algorithms
Hi, I want to do a careful measure of mic-to-net and net-to-spkr delays in sip media engine and to make it really precise I need to know delays, introduced by Speex algorithms. In particular, I'm interested in delays of: 1) encoder in NB, WB and UWB modes, 2) decoder (I guess it should be 0?) 3) resampler. I think it varies depending on input rate to output rate ratio. Any generic formula or
