He mentioned that he uses mics to phase cancel each other to shape the sound like an EQ. But, I've always viewed phase cancellation as a bad thing. Does anyone have any insight into this, or how he and Bob Rock would have acheived something like this? Thanks! thumbsup |
You seem to confuse this with phase cancellation on stereo signals, where the right side cancels out with the left side and is mostly not wanted
But sometimes when you use two different microphones or different mic locations on a mono source, by reversing the phase you can get rid of unwanted frequencies that cancel each other out.
You use the phase cancellation as sort of sound-shaping tool.
This is a widely used technique especially on guitars. You flip the phase of one mic and sees what gets you closer to the sound you are looking for.
