One tom, two mics and phase issues...

Just a quick question for you guyes...

Say you have two mics on a tom... on on the top and on one the bottom.
The one on the bottom is phase-flipped. Both mics point directly at the heads with zero degrees. This should cause no phase-canselation, right?

However, would turning the top mic 90 degrees so it point horizontally with the head cause any phase canselations?

This would make a 90 degree angel between the top and bottom mic...

Since the drum is struck on the top (beater) head, there is more delay before the bottom mic senses the impulse. Of course, the bottm mic is primarally there to get the sound of the bottom head...

Any time you have two microphones, even if one is phase reversed, you will get nulling at some frequencies.

Is this a trick question?

If you record in a DAW, try lining up the tracks in time by looking at the waveform and lining them up. There is a big thing about this in this month's issue of Recording.

If you don't record digital, or dont want to use this approach....I dont know what to tell you, other than play with the mics till they sound good, Haha.
