Sound source positioning the ring matrix microphone
Product description:
USB 2.0 interface;
Ring matrix microphone;
360° omnidirectional sound pickup; sound source positioning, LED indication direction; support 12C coordinate output;
Suitable for intelligent robots, AI artificial intelligence equipment and other scenarios:
The array microphone board has a built-in circular 5-way microphone array algorithm, including echo cancellation, speech enhancement, sound source localization, noise suppression and automatic gain algorithms. It can realize omnidirectional sound source localization and calculate the angle and azimuth coordinates of the human voice, which is very suitable for the sound pickup function requirements of application fields such as human-computer interaction and AI smart devices.
