Sound zoom method, medium, and apparatus |
摘要 |
A sound zoom method, medium, and apparatus generating a signal in which a target sound is removed from sound signals input to a microphone array by adjusting a null width that restricts a directivity sensitivity of the microphone array, and extracting a signal corresponding to the target sound from the sound signals by using the generated signal. Thus, a sound located at a predetermined position away from the microphone array can be selectively obtained so that a target sound is efficiently obtained.
