Claim 21:
22. An apparatus to determine a direction of a source of a sound relative to a computing device, the apparatus comprising:
means for generating a vector of values corresponding to a cross-correlation of first and second audio signals corresponding to the sound, the first audio signal received from a first microphone of the computing device, the second audio signal received from a second microphone of the computing device; and
means for using a machine learning model and a set of the values of the vector to determine the direction of the source of the sound, the set of the values of the vector corresponds to a segment of the vector including at least a threshold number of the values, the threshold number being at least twice a number of samples corresponding to a time difference of arrival for a sound originating at a point collinear with the first and second microphones.
