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 2):
The apparatus of  claim 1 , the one or more processors to implement:\n a conditioning filter to filter a playback audio signal, the playback audio signal comprising a third audio frequency range, using a filter tuned at least in part on an inverse response of the speaker, the audio input device, and an acoustic path to generate a second audio signal; and an oscillator to operate on the second audio signal to generate the portion of the audio output signal.
