Good explanation.
Another advantage of the FIR filter is that it has flat group delay.
That means the delay through the filter is independent of frequency,
unlike in an IIR filter. Flat group delay results in less distortion of

Hi Mike. I have 2.20 loaded and my comments below are what I am
experiencing. I don't see how it's possible to have the same level of
audio with the NR engaged. The filtering will naturally reduce the audio
level, unless the K3 has a gain adjustment for the filtered audio like
the K2 has.
I guess I should also say that this has always been my experience
with the K3 NR. I really didn't think it was a problem though. I just
thought I would add my comments because other folks started saying that
they had the same level of audio with the NR on or off. Maybe their NR

My unmeasured ears tell me that when NR is engaged, the overall audio
