Abstract: Head-wearable apparatus to generate binaural audio content includes a first stem coupled to a first microphone housing that encases first front microphone and first rear microphone that generates acoustic signals, respectively. First microphone housing includes a first front port that faces downward and a first rear port that faces backwards. Apparatus includes second stem coupled to second microphone housing that encases second front microphone and second rear microphone that generate acoustic signals, respectively. Second microphone housing includes second front port that faces downward and second rear port that faces backwards. Apparatus includes binaural audio processor that includes beamformer and storage device. Beamformer generate first beamformer signal based on acoustic signals from first front microphone and first rear microphone, and second beamformer based on acoustic signals from second front microphone and second rear microphone. Storage device stores first and second beamformer signals as a two-channel file.

Abstract: Method to perform dynamic beamforming to reduce SNR in signals captured by head-wearable apparatus starts with microphones generating acoustic signals. Microphones are coupled to first stem of the apparatus and to second stem of the apparatus. First and second beamformers generate first and second beamformer signals, respectively. Noise suppressor attenuates noise content from the first beamformer signal and the second beamformer signal. Noise content from first beamformer signal are acoustic signals not collocated in second beamformer signal and noise content from second beamformer signal are acoustic signals not collocated in first beamformer signal. Speech enhancer generates clean signal comprising speech content from first noise-suppressed signal and second noise-suppressed signal. Speech content are acoustic signals collocated in first beamformer signal and second beamformer signal.
