Parallel processing is an excellent way to introduce subtle changes in a mix, and nothing suits it better than parallel compression.
Parallel compression operates from the ‘bottom up’, so it doesn’t crush in the way that ‘top down’ compression does. It’s great for filling out a part, enhancing quieter details and making everything sound fuller and warmer without removing any of the punch. And luckily, with modern computer-based recording, it’s a piece of cake.
