Can anyone post me some audio examples of Phase Problems?

I've seen references to them regarding guitars, cymbals

But I can't seem to wrap my brain around it.

Any help would be appreciated
thanks
 
I had an example in one of my mixes but i don't have anything to post..

For some reason i had the idea to do a stereo recording of a bass guitar, using a shure sm 58 dynamic mic, with a LD condensor mic. So i had one panned left one right, and it sounded kinda wierd, no real bass frequencies.

I muted one, and it got better, i panned it center and A/B'd it between having the two panned, or just one centered, and the one centered was much better. Like there were tons of frequencies missing before. Phase cancelation.
 
If you reverse the wires (+ & - ) on ONE of two home hi-fi speakers, you've reversed the phase in context. You'll here some swirling that'll give you the right idea


Peace

A good experiment to understand how phase cancellation can affect your sound is to take a track and duplicate it to a new track. Select that track and Invert it with your software. If you are using a mixer/tape recorder then bounce the track to a new channel with the Polarity reverse button pressed.

Pan both channels to dead center and as you bring up the polarity reversed channel it will gradually weaken the other track until eventually they will both dissapear. It will only work perfectly on a DAW but you might have a slight ghosting of the sound still audible.

That is also a good trick when you are comparing two tracks to see if they are really exact copies. Bit perfect exact copies will cancel eachother out completely.
