Invert a Wave? Why!?

When you invert a wave sample, visually turning it upside-down, what is actually being done to the wave sound?

Does it have any benefits to do this by itself?

Does it have any benefits or is there a difference in dynamics when you layer an inverted sample over an un-inverted sample?

Why invert a wav?

i'm not sure how to explain.....let's say a wave's startpoint is at 0-level (the horizontal line in the middle) and the waveform travels up first, and then down again. if you would invert this sample, it will go down first, before going up.
Whatever, it's called inverting the phase, and when you're layering, you might want to use samples that "go up" only, or at least don't mix "up and down or something called phase canceling will occur.

that probably didn't help you much, didi it?

Electronic Musician ran a nice little piece on audio phase this month. Here's a link to the online copy of the article:

That's a good article.

Yeah, just do some reading on phase cancellation.

you can get a psuedo high pass filter with the mpc if you stack two of the same sample on the same pad...make one of them inverted (use sf or cep) and then just start using the filtering on one of the pads.....

high pass effect!
