1ï¼Suppress the howling which is caused by acoustic feedback in the sound system
2ï¼The adaptive filter can be switched between "fast" mode and "precise" mode.
3ï¼The fast mode is suitable for occasions where the position of the microphone changes frequently, such as in a conference system equipped with multiple microphones and switched between them.
4ï¼The precise mode is suitable for occasions where the microphone position is fixed, for example, a forum where the acoustic environment is relatively stable.
5ï¼The adaptive filter can converge at a slower speed, thereby effectively suppressing more reflection components
6ï¼Before acoustic feedback occurs, an additional gain of up to 12dB can be obtained, depending on the acoustic environment and the selected operating mode.
