The way the new beta NR works is:

Fx-y

x selects the length of the filter.

F1 = 121 taps, F2 = 91 taps, F3 = 61 taps, F4 = 31 taps

(The Beta 3.25 release used FIR filters of 61 taps.)

y selects values of Beta (gain), decay, and delay (how long the NR 
algorithm waits to process a signal)

(The Beta 3.5 release used the "x" parameter for these selections)
