The folks who told me were several fellow mastering engineers.

Sorry no.
I first head this from chief mastering engineer David Collins, A&M mastering up to its demise.
He told, on the mastering list, that a person came from AGFA with a complete receipe on paper, giving details on which micro wave oven to use, time in the oven so on.
As far as I know this process was patented.
