Well i aint sure what you mean really.
Phasing occurs when two seperate waves are out of phase with each other.
This produces a chorusy kinda swirrly sound.
 
Vertical is amplitude. Time (phase) would be horizontal and between two tracks as Ecktronic said. It's not uncommon to have an asymmetrical wave. One source I've noticed is from circuits with a bit of overdrive in them.

edit: I just noticed the bluetube in there. Bingo.
 
thats what i thought..thats what some1 told me when i sent them a cool edit file... i wasnt sure so i thought i would just post it.... on another note does wave look okay?? thats just a raw recording(rap btw)i know i have a noisey room so i get alot of noise
 
Yeah, ok. And the circuit don't know 'signal' from 'noise'.
It would be interesting if you dial out the tube in the pre if it goes even.
 
^^hmm i dont understand u talking to a semi newbie.....dial out pre??
 
Your preamp has a vaccum tube in it. It's an old fashioned way of getting the signal to sound warm and provides some light distortion. If you can disable the tube, you might have better luck, I believe they're saying.

Yep. If I recall, one of the two volume/gain knobs drives (or mixes in?) the tube. The other is the clean/solid state side.

A little reading can clear that right up.

"Drive. The Blue Tube provides a Drive
potentiometer on each channel for controlling the
amount of signal routed to the 12AX7 vacuum tube.
This feature lets you control how much saturation of
the signal occurs. Greater levels of tube saturation
give the signal greater warmth and a richer sound."

Try turning 'drive off, make up the difference with the 'gain'. Presumably, that's the clean side of it.

When the waveform is off centered it is called DC Offset. I don't agree that distortion on the preamp is the cause.

DC Offset is pretty common with less then stellar input circuitry and apart from eating up some of your headroom the affects are pretty negligable. Most DAW programs have a tool for "Removing DC Offset" and will center the waveform as best as possible.
