KVR Audio

I just finished mixing a track. While trying to create an MP3 version in the audio editor, I noticed the Phase correlation meter is half way towards right. Does it have to be at the center? I am not able to figure out what is causing this. The song sounds fine and I don't hear any phasing issue as such. I do know that recordings multiple mic placement cause phasing issue, but that can be ruled out as there are no tracks which was recorded live and I am not using any samples either. Apart from this is there anything else that may create phasing problem? Where should I look at? To give you little more detail, the song has only 10 tracks, all are vocal Choirish type of sounds coming from a plugin. No samples used, though I bounced one or two tracks to save CPU. Used all onboard effects that comes with the plugins, so no reverbs, etc. If you wanna know anything specific please ask.

This is how it looks like when I play it in the audio editor (Acoustica BE)

Listen to it in mono and you'd be able to hear this problem.

Ok, my next question would be how to fix it? What should I change to fix it?

Obviously an audio clip is worth 1000 static pictures, but that looks like a perfectly healthy stereo signal to me. No phase problems indicated in that readout at all from where I'm sitting.

To be very honest, when I listen to the song it doesn't sound like it has phasing issue. This track is for a contest so cannot share it here. I was not even sure if it was a problem to begin with. I just saw the yellow square at the bottom stays between 0 and 1. That's why I asked first whether it means a problem. Does it need to be at the center all the time?

No, it doesn't have to be at the center. Closer to 1 is better.

Yep, between 0 and 1 is generally what you're aiming for. A value of 1 would mean you're dealing with a mono signal. I wouldn't worry too much about the occasional drift to the left of 0 unless it causes obviously audible issues, and always bear in mind that a lot of compromises made for the club (ensuring mono compatibility etc) aren't necessarily conducive to home listening.

Thanks hebb and cron. Really appreciate your help.

I don't like those squiggly meters, I like the one in SPAN. It's only when it slips into -1 that you have phase issues.

Phase correlation analysis questions.
