Abstract: Exemplary aspects of the present disclosure assist in phase alignment for systems having multiple audio sources. For example, in a system having plural microphones, phase alignment may also be assisted by sampling the microphones at the appropriate time relative to when the samples are placed on the audio bus. Further, phase shifts between audio samples are reduced or eliminated by keeping a sample delay constant for samples from the same microphone. Such manipulation of the audio samples reduces phase shifts which reduces the likelihood of an audio artifact capable of being detected by the human ear and thus improves consumer experience.

Abstract: A microphone circuit includes a microphone configured to generate a microphone signal. The microphone circuit also includes a processor configured to perform sound detection based on the microphone signal and to determine whether to enable a component based on the sound detection. For example, the processor may be a digital signal processor (DSP) of the microphone circuit and the component may be external to the microphone circuit, such as a coder/decoder (CODEC), another DSP, and/or an application processor.
