Abstract:
Techniques related to active acoustic echo cancellation are discussed. Such techniques may include generating an audio output signal having a portion thereof corresponding to a first audio frequency range to negate a response of an audio input device to an output from a speaker in a second audio frequency range at a response negation rate and decimating an audio input signal based on the response negation rate to generate a resultant audio input signal.

Claim (Index 12):
The method of  claim 11 , further comprising:\n generating a filter response for filtering the playback audio signal, wherein the filter response minimizes a difference between a third audio signal comprising the first frequency range of the audio input signal and a fourth audio signal comprising the second frequency range of the audio input signal.
