This is the theory for sounds where one specific
sound doesn't start with its own climax.
Simpler said, the
sound has to build up volume first and the climax starts 5-30 milliseconds later.
Looking at another perspective, it is very likely that
drum sounds instantly reach their climax where as (mostly noticeable) EDM sounds that have some kind of distortion to them, don't reach their climax instantly, but get them more likely delayed.
