Signal Noise

a = lorentzfit1(x,y,a0) LORENTZFIT1 fits the input Y(X) with a Lorentzian function of the form Y'(X) = 1./(A(X.^2 + 1)) (i.e. 1-parameter model). INPUTS X : Independent variable values Y : Dependent variable values [Y(X)] OPTION A0 : Define initial guess for parameter A OUTPUT A : Lorentzian... Platforms: Matlab

MR Noise is a broadband noise reduction processor. It distinguishes itself by being both great sounding and incredibly easy to use. Like most noise reduction systems, MR noise works in the frequency domain, and requires that the noise spectrum be learned before noise reduction can commence. If... Platforms: Mac
