Hi, Alexey! It’s great to see you here.
The applications I was primarily thinking of was use of (or potential use of) LP equalizers in music production: Recording, mixing, mastering. I’m curious to hear how other engineers may choose to use them or not to use them in music production.
Yes, Linear phase in more “scientific” applications is often used behind the scenes, such as in multiband dynamics processors.
So many people don’t realize the issues that can occur with minimum phase equalizers. For example, MS manipulation with minimum phase equalization can mess up the stereo imaging.
