well, I am using the high pass filter, and basically the kick drum isn't as heard as much as it is without it - that's obvious. however, what it does sound like is like a clicking noise.
Now, if I want to fix a section of kick drums, I notice that I can hear the new kick drum (which yes, is obviously much louder than the clicks coming from the overheads), however, I can also hear the clicks coming from the overheads because they do not match with the kick drum hits.)
Since the overheads are picking up various cymbols during this section of music, I don't exactly know what I can do to remove the kicks from the overheads...atleast so much as to not be as noticable in the mix with I do fix a section of drums.
What's funny - is I recorded my band awhile ago with sm57s as overheads (that's all I had), and I recently listened back to those recordings, and I didn't have this problem. I am of course using pretty decently condensers now - so maybe they just pick up a whole lot more.
The idea of covering the kick drum makes sense...in fact, i've seen tons of people do that, and I guess it now makes sense why.
Also, I guess the other alternative is to record the drums/cymbols separately like that one engineer guy did (I don't rememebr his name, but I remember reading it on here awhile ago...)
