Be sure you are resetting the "Reduce By" setting to 10dB or less - the
default (which is not changeable) is 40 dB - way too much reduction for
anything we do. If the reduction is under 10 dB the artifacts are generally
negligible.

The cleaner the sample is before noise reduction, the fewer artifacts,
that's true.
