METHOD, APPARATUS AND SYSTEM FOR MICROPHONE ARRAY CALIBRATION |
摘要 |
<p>A method, apparatus and system for microphone array calibration include recording audio using at least two microphones, which comprise an array of microphones, using a target microphone of the array of microphones, determining an attenuation factor for audio originating from respective locations of other microphones of the array of microphones, using a target microphone of the array of microphones, determining a delay factor for audio originating from respective locations of other microphones of the array of microphones and implementing the determined attenuation factor and delay factor for removing audio originating from respective locations of the other microphones of the array of microphones from an audio signal captured by the target microphone. The method, apparatus and system then further include removing audio originating from respective locations of the other microphones of the array of microphones from an audio signal captured by the target microphone using beam-forming techniques.</p> |
