fb_filter_decay_en Enable Filter Decay Mode In Feedback Reduction Algorithm
Description
This parameter enables (1) or disables (0) filter decay mode for the feedback
reduction algorithm. If filter decay mode is enabled, the adaptive notch filters
can slowly decay to 0 dB if no singing is detected at that frequency. This mode
is useful in rooms with high noise or where there is a lot of motion.
