; This filter uses the LMS algorithm to adapt dynamically
; the FIR filter coefficients.
; Primary is noise and desired signal
; Reference is noise only
; It works better at removing periodic noise.
; There are two outputs :
; - Correlated output is the output where the noise was substracted.
; - Uncorrelated output is what was substracted from the output.
input Primary, Reference;
output OutCorr, OutUncorr;
; Mu is a coefficent to control the convergence speed. You want it
; as big as possible without causing the filter to diverge.
