Phase alignment in an audio bus

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.
