Some test records have unmodulated grooves. The Cardas record is one.
Of course every LP has blank grooves in the runout area. Using those to set up your noise profile would be ideal. Different LP's have different vinyl formulations and therefore different noise levels. The only question is, how much running time is required to set up the noise profile?
That may be software-dependent, and I have no experience with such software.
