Abstract
An apparatus and method for an audio user interface solution that avoids the time variation problems seen when using an acoustic echo canceler in an audio system. The solution as disclosed and claimed herein results in lower CPU usage in the audio system because a synchronous sample rate correction (SSRC) is performed on the sample rate multiple rate content and the asynchronous sample rate correction (ASRC) is applied on a small number of signals used to feed the ASRC.
