Abstract: A wearable audio device is provided. The wearable audio device may include a first array of microphones linearly arranged on the wearable audio device at a positive angle relative to a horizontal axis of the wearable audio device. The microphones of the first array may be configured to capture far-field audio. The wearable audio device may include a second array of microphones linearly arranged on the wearable audio device at a negative angle relative to the horizontal axis. The microphones of the second array may be configured to capture near-field audio. The wearable audio device may include circuitry arranged to (1) generate a user voice audio signal based on the captured near-field audio, (2) generate a desired audio signal based on the captured far-field audio, and (3) generate a differentiated signal based on the desired audio signal and the user voice audio signal.
