EXPERIMENTATION
As the traditionnal and available sound processing solutions did not allow me to achieve what I had in mind, I worked on the development of specific algorithms - with adjustment variables - that could carry out this "update" of the Mastering from the original sources.
So I did not use the principle of Peak Limitation (see the dedicated article), and only the 1986 audio was chosen to perform an "alternative" ReMastering.
Excerpts to listen to below.
