I mastered some tracks, not my own, https://www.youtube.com/watch?v=-tITIrMNAaw (орининал= original recording, and освоил= after i mastered it). Its to compare how it sounds from the original to the mastered version. The mastered version sounds like it has too much of an echo, what could I be doing to cause this? I've tried many variants of removing what I think could be the cause, to where i usually just end up with an indistinguishable sound from the original. Any insight would be appreciated.
