Nope!
From the User Manual:
Invert
Reflects the selection about the x (time) axis, turning the waveform upside-down. This produces no noticeable effect in mono sounds and has a slight effect in stereo sounds. Inverting a single channel of a stereo sound will produce a simulated surround-sound effect.
It inverts the phase of the signal... It makes the speaker move in, when it used to move out, and vice-versa.
Besided creating a "simulated-surround effect", inverting one channel will kill most of the bass because the left and right woofers are moving in opposite directions. Higher frequencies don't cancel-out as much, due to the shorter wavelengths, random reflections, and some other acoustic-theory stuff....
Well,
some higher frequencies might be canceled at some points in the room...
The
Remove Vocals effect also works by inverting one channel. After inverting, the channels are summed (mixed). With one channel out-of-phase, everyting that was identical in both channels is canceled. In fact, the
Remove Vocals effect is done by mathmatically subtracting one channel from the other.
...if my voice was very loud and the other person i recorded was very lowlevels and i use invert, would it boost theirs and decrease mine dramatically?
Actually, I don't know how you could "invert" the levels... It's probably mathmatically easy, but the process would probably cause lots of distortion and undesired side-effects. For example, quiet background noise might become like a jet engine!
Compression tends to make the sounds more-equal. The
Auto Gain effect is a special kind of compression. Compression can make the quiet sounds louder (louder than they were before compression... not louder than the loud parts.) Or, compression can make the loud sounds quieter (than they were before). Or, both.
Expansion is the opposite. makes loud sounds louder and/or quite sounds quieter. A noisegate is a special kind of expansion. It makes quiet background noise quieter, or even absolutely silent.
