Cancellation - The destructive interference of two or more sound waves. Waves of similar frequencies and amplitude, but of opposite phase (180°F) produce mutual cancellation effects.

Hi all, Sunday i've finished the acoustic treatment in my home studio and everything seemed to play properly, but when I sat down at the listening position I noticed a phase cancellation on the low.
From the measurements there's a hole of -10db at 63 and 66Hz
I followed all the directions to the acoustic treatment, but this thing I do not know how to handle it.

Hi. If I Micing a guitar amp, and I set one mic close and the other back, which creates a tonal blend preferred by the musician, I put a delay on the first mic so that the signals are coming to the board simultaneously to avoid phase issues. I checked the wav files and they are aligned -- as well as using my ears. Sonically, all is well.

Hey,

I'm taking an audio class and I'm on a homework question I can't seem to remember the answer (even though it seems to be a pretty easy question).

"If you cause phase cancellation at 1000hz, you experience cancellation at 2000hz, 4000hz, and 8000hz. What is this kind of phase cancellation called?"

Could anyone tell me what this is?

Does anyone have any insight on frequency cancellation as it pertains to an entire mix. I think I might be experiencing it between the lead vocal and the guitars in one of my mixes. The guitars don't play during the verse and the lead vocal sounds nice and full, but when the guitars come in on the chorus the lead vocal sounds a little thin.

Hi,

I'm working on a holiday Cd with my choirs right now and hope to start recording in 3-4 weeks. I've been happy with using spaced omnis in the fair/poor room I record in and am beginning to experiment with MS to see if that technique will provide better results in the space.

What are phase problems/cancellation? I haveh eard about it being when two or more mics are "out of phase". i would love to know what this is/how to fix it/how to tell if it's happening. thanks.

I am a very inexperienced rookie when it comes to recording and I don't quite get the concept of phase cancellation. Could someone give me a rough explanation? thanks.
