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
