it's fairly easy to just use a sliding correlatorĀ  and sync up the audio for the compare/ MSE computation etc

you might want to oversample it say 4x inside the PC before the correlation- up to 32ksps from 8ksps

assumption is it is all done in the digital domain.

if done with SSE instructions, can do 128 bit worth of compare for the correlator per clock cycle.. (or 256 for the new AVX inst set)
