[QUOTE="John Roberts, post: 19566, member: 126"] Re: Polarity invert toms ? Drums, like all other instruments generate AC sound waveforms, while there is a polarity associated with the initial transient hit. Your question is based on the assumption that we actually want a positive pressure attack from toms. BTW the kick drum, if mic'd from the resonant side does generate a positive pressure attack. Tom's are generally neither pointed at or away from the audience, so the natural way we experience these waveforms un-amplified, is actually at a right angle to the drum heads. I believe absolute polarity "could" be audible when reproducing drum hits, while subtle. When close micing a drum kit with multiple mics there are far more sound altering consequences from exactly where the mics are pointed at a given drumhead, and how multiple mics interfere if they pick up the same sound field. Most polarity tweaks around drum kits are to get the mics to play nice together. If concerned about polarity, make the kick drum front mic your "in polarity" reference sound, and then get the others to play nice with that. JR [/QUOTE]
