Digital filtering using LTI systems is by definition a convolution operation. >> b = fir1 (40, .5); % generate 40th order lowpass FIR filter at half the nyquist >> filteredAudio = filter (b, 1, noisyAudio); % since this is FIR, the only feedback coefficient is 1 at y_n. But, this will not remove white noise. It will only attenuate frequencies (including those in the original audio …
