My friend showed me a plugin that allows to accurately time and phase align multi tracked drums. And it makes an obvious difference when used on raw tracks, but I noticed that it doesn't always mean better sound during mixing stage. Once I start processing tracks with gates, eqs and compressors sometimes the only thing I need is a basic phase flip switch. After a few tests I don't actually feel the need to use those auto align plugins. I actually feel that those time differences between different mics are an integral part of the drum sound.
What is your approach?
