Abstract: A head-related transfer function (HRTF) generation system includes one or more processors configured to retrieve first image data of a first ear of a subject, compare the first image data with second image data of a plurality of second ears to identify a particular second ear of the plurality of second ears matching the first ear, identify a template HRTF associated with the particular second ear, and assign an HRTF to the subject based on the template HRTF.

Abstract: An apparatus comprises a plurality of microphone units including at least a first microphone unit and a second microphone unit, each of the first and second microphone units comprising a microphone, an analog-to-digital converter, and a local memory. The microphone is configured to capture an analog audio signal. The analog-to-digital converter is configured to convert the analog audio signal created by the microphone into a digital audio signal. The local memory is configured to store the digital audio signal. The apparatus further comprises. a controller unit comprising a processor configured to process the digital audio signals. The first microphone unit and the second microphone unit are operatively connected to the controller unit in a series configuration, the second microphone unit being configured to output the digital audio signal to the first microphone unit, and the first microphone unit being configured to output the digital audio signal to the controller unit.
