Hi John and all,
In fact, I am also looking for the time alignment
of two samples, one is the original, and another is decoded. My problem is to
estimate the time delay caused by audio coding.
I try a classifical estimation method, which makes
use of envelope based cross-correlation function. That means, the envelopes of
two samples are computed firstly, and then calculate the cross correlation
function of these two envelopes, and then select the time length corresponding
to the maximal correlation as the delay.
I hope this method will help you, and if anyone has
better approaches, please let me know, thank you very much.
