US Patent 10575117 Directional sound modification

Various embodiments set forth techniques for directional sound modification. In one aspect, a system includes a plurality of audio sensors configured to acquire sound from an environment and at least one processor coupled to the plurality of audio sensors. The at least one processor is configured to determine a direction within the environment, generate an audio signal based on sound acquired from the direction within the environment, and transmit the audio signal to at least one audio output device to generate audio output. The audio output combines with sound from the direction within the environment to produce a modified sound.
