See REW measurements of my untouched system and after Convolution correction:
Congratulations … How do you like the way your system playback sounds with this correction?
Thank you!
Well – this was not about sound actually but about to learn how to create FIR files that would make Convolution minimize channel differences and deviation from a given target curve.
The perceived focus of the soundstage should be more refined… 
The most surprising fact for me was that my »AI agent« is able generate suitable FIR files for me. Uploading the »before« measurement plus my desired target curve was all it takes actually.
Neat.. Super Intelligence is going to change the playing field for digital-audio playback in many ways… Might homogenize the experience for all…
