Phase cancellations have at least as much to do with mic position as with mic angle. angling the mics is not a magic solution. Most cardioid mics have plenty of pickup at 90 degrees. It sounds like what you're describing is the classic "X/Y" stereo mic technique, with a pair of cardioids placed so that * The mics are angled 90 degrees relative to each other, and 45 degrees relative to "center" * The mic heads are placed as close together as possible. but there are other "classic" stereo techniques... mid-side, spaced pair (usually omni), binaural... you'll see plenty of top-tier engineers recording drum kits with a pair of cardioid overheads over opposite sides of the drum kit and pointed more or less parallel, which would fit in the "spaced pair" category though most often it seems cardioids are used instead of omni. check the rec.audio.pro FAQ for more good info on stereo micing. (and tons of other stuff.) http://recordist.com/rap-faq/current check questions 10.1 and 10.2. and here's a great rambling usenet post about minimalist drum miking, a lot of it targeted for rock recording but the basic ideas would apply to lots of stuff: http://www.mercenary.com/3micdrumstuf.html and here's a great article about unorthodox drum recording tricks: http://emusician.com/ar/emusic_underground_drum_sounds/ >It has to do with the the amount of time it > takes sound to hit one mic and then the other. right, that's why position is important. > But please trust me. If you don't do the cross pattern you (could) hear unwanted sounds (and/or dropouts). dropouts?? what on earth does mic technique have to do with dropouts? -- Paul Winkler http://www.slinkp.com
