Abstract
A method of processing audio received at a plurality of microphones in a vehicle includes receiving the audio as a first audio stream and second audio stream at respective first and second microphones that are positioned at different locations within the vehicle; creating a first digital time series and a second digital time series that represent the first audio stream and the second audio stream, respectively; calculating a delay that exists between the first audio stream and the second audio stream based on a cross-correlation of the first digital time series and the second digital time series; and processing the received audio using the calculated delay.
