How to synchronize the reference signal and the echoed signal? - Ding Ke - Dec 15 8:06:00 2005
Hi All
I write a sound recording tool to generate the test vector for AEC. First,
a sound file is played as the reference signal (far end speaker) through
the loudspeaker. In order to simulate the near end speaker, the person say
some words when it is recorded at the same time. But how to synchronize the
reference signal and the recorded echoed signal? I find it is very hard to
do this. Is anybody here have some ideas on this? or have some experience?
thanks
Kevin
