I haven’t. One thing Sidis hipped me onto is Izotope Ozone. It’s a paid mastering plugin for your DAW that provides a lot of mastering tools like compressors, adaptive limiters, spectral imagers, etc…. What differentiates it is that it has a “master assistant” feature that uses AI to help you get in the ballpark with a master, then you can kind of tweak by ear or meters from there.
The AI assistant can be used in two ways. Pick some parameters like intensity and vintage/modern and click go, or provide a reference track for the AI, click go, and it analyzes the reference track to inform its decisions. Either path you take, the end result is that it builds out a master processing chain that is applied to your mix on the master/stereo out channel in about 10 seconds. You can then listen and tweak all the knobs and sliders until you are happy with it and do a final master bounce.
In practice, I like to provide a reference track that has a final master I like. It can be anything, a Steely Dan, Pantera or Hans Zimmer track. The AI gets me in the ballpark and I’ll usually spend ~hour tweaking, dump a master, give my ears a rest, listen to the dump on all the speakers I can from monitors to car stereo to cell phone, note any tweaks I think need to be made, and then repeat until I have a final master that I like. Usually it’s it’s one or two iterations so this has pretty much cut my mastering process down to 2-3 hours and the result is as good or better than what I was producing on my own with 8-16 hours spent mastering a track
Ozone 11 has a 10 day free trial, a standard version that is $149 and a pro version that is $299. I wouldn’t recommend the elements version for $39 as it does not have the AI feature.
