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 15):
At least one machine readable medium comprising a plurality of instructions that, in response to being executed on a device, cause the device to:\n receive an audio input and providing an audio input signal responsive to the audio input at a first sampling rate via an audio input device; generate an audio output signal comprising a portion thereof corresponding to a high audio frequency range, the portion of the audio output signal, when provided as first audio output from a speaker, to negate a response of the audio input device, at a response negation rate, to second audio output from the speaker in a low audio frequency range; and decimate the audio input signal based on the response negation rate to a second sampling rate less than the first sampling rate to generate a resultant audio input signal.
