Trance music production techniques (Tutorial)

@matako07 There are probably more technical ways to figure this out, but
here is the practical way.

#1 just check to see that none of the mics being used are in reverse
polarity from each other (that means the manual phase adjuster that flips
it 180* hasn’t been turned on) (This is usually a symbol which resembles an
O with a line through it). This can happen many times in mic placement. If
you are using 2 mics on the snare (Top and Bottom) and they are practically
facing each other, these could have some full or partial phase
relationship. Try re-positioning the mics or flipping on the polarity
switch on purpose because the natural placement has caused phase
cancellation, so you want the polarity to be reversed.

#2 try just solo-ing out two channels that you suspect are causing a
problem, then flip the polarity on one of them and see if the sound gets
suddenly louder or quieter. That would be a sign you have a polarity issue.

Again, there are a ton of other things that could play out here but these
are the two common things that come up in live and in recording.

Once you’ve recorded -with, lets say, 8 mics (2 kik mics ,2 snare top &
bottom, hihat, toms) how do you check for the mics that are cancelling …
How do you compare the wave forms and know which one to adjust?? In other
words…how do you know Which Mics are cancelling?
