Anyone knows how microsoft AEC can deal with mismatches between clocks of capture and render streams?
...delay drift between near-end and far-end voice which is caused by different sample rates even if it is largely eliminated by the resampling. Moreover, the residue difference will cause overflow or underflow of the buffer in a long time, which is a disaster to the echo canceller.
Maybe this paper (Pawig, M., Enzner, G., and Vary, P., Adaptive Sampling Rate Correction for Acoustic Echo Control in Voice-over-IP, IEEE Transactions on Signal Processing, Vol. 58, No. 1, January 2010) points out a correct direction. In this paper, the far-end signal is resampled before send to AEC. It estimates the dela...
