ADAPTIVE FEEDBACK CONTROL

AFC C55x , C64x , C64x +

In many acoustic applications, the presence of feedback can cause a resonance to occur. Whether or not the resonance occurs as well as the frequency of the resonance depends upon many variables: is a function of gain/loss, acoustic reflections, room size, and system delay.

Adaptive Digital's Adaptive Feedback Control algorithm analyzes an input signal, determines whether or not there is a resonance, and eliminates the resonance while minimizing the effect on the desired signal.
