Thank you for your fast reply.
I am trying it now, but I may be missing some detail. Do I have to bypass the master section all the time when I swap between tracks? This step definitely affect my audition perception.
Basically I have both files, one on montage tab (commercially released track) and one on standard wave editor (unmastered track) but as I add effects on master section, it affect both files.
Last week, a friend showed me his A/B mastering technique using a DAW (Pro Tools). Basically he used the “solo” button to swap between track and had a instantaneous feedback between the reference track and the unmastered track. A single click task.
While he created his mastering chain, he would simply “swap” and balance his unmastered track accorddly. A very effective way without losing perception of loudness.
It would be good if can could just do it in a simply click. Without swap track and bypassing the master section. Hope you understand what I mean.
