Couple of points, for what its worth, more of a realistic summary.
The "ideal"(if there is such a thing, 'coz in the end its all about taste?), in drum recording is to use the least possible number of microphones with which to arrive at a full sound spectrum.
As THE most prevalent problems with recording drums are phasing problems (well, the second problem really, the first one is called a drummer) ...... the lesser the number of mics, the lesser the potential problem.
The least number of mics you can use to create a somewhat accurate stereo image is three, 2 overheads and one kick.
HOWEVER - getting a good sound from 2 OH's and a kick depends completely on:
- The quality of Microphones.
- The quality of preamps
- The acoustics of the recording space
- The actual sound of the kit (believe it or not).
The sound resulting from a good sounding kit, recorded in a good acoustic space, with premium mics and pre's is VERY BIG and ambiant, certainly not something you'd want on all kinds of recording / music. Forget about a "tigh" or "punchy" sound.
Also - what you record is what you get, forget about pulling that snare / tom/ hat up or down once your tracking is done. In other words, you will loose your flexibility.
Your overheads and kick SHOULD ALWAYS BE YOUR PRIMARY MICROPHONES in recording a set. Get them to sound right, and you are more than halfway there. See everything else as an addition you might, or might not, need.
If you do use more microphones, most of you use DAW's, so you have no excuse for phasing problems, as you can edit tracks. So, if you insist in fucking up your mic placements, at least you can fix it. But for christ sake........ LEARN from looking at your waves and try and get it right at the source!
So, if you insist on just using 3 mics, fine, but if you have one spare, you'd be nuts not to use it.
Over here we normally mic everthing
2 x kick, 2 x snare, hat, toms, cymbals, 2 x overheads, 2 x room.
BUT - inevitably over 60% of the sound will be one kick and 2 overheads.
Perhaps a pretty decent example of a more or less typical sound for a three mic drum recording would be the song step at
http://uru.iuma.com. Over 95% of the track is two overheads, placed through the M-S encoders of a Precission 8 preamp (for stereo imaging purposes) and a kick mic in front of an extremely well tuned drum. The "add-on's" are a couple of dB High Hat attack. The hat is a typical example of why you need more mics, its a tight, fast pattern, which would have gotten lost with just three mics, but all it needed was a couple of dB of the top end of the hat to make it shine through. And in the "middle bit", on the tom rolls, the room mics took over, again through the M-S encoder for good stereo image.
Other mics were placed as normal, but not used.
