Patent ID: 8411880

Claim:
A method for improving sound reception on a mobile device, comprising: obtaining a first sound signal from a first microphone; obtaining a second sound signal from a second microphone, wherein each of the first and second sound signals includes at least a portion of a first source signal from a first sound source; selecting the first sound signal as an output sound signal for a first time frame; obtaining a first signal characteristic for the first sound signal over a second time frame, wherein the second time frame is subsequent to the first time frame; obtaining a second signal characteristic for the second sound signal over the second time frame, wherein both the first and second signal characteristics are associated with a same signal characteristic; changing the output sound signal by transitioning from the first sound signal to the second sound signal during the second time frame if the second signal characteristic is greater than the first signal characteristic by at least a minimum threshold, wherein changing the output sound signal from the first sound signal to the second sound signal includes: gradually decreasing the contribution of the first sound signal to the output sound signal, and gradually increasing the contribution of the second sound signal to the output sound signal.
