Zoom H2 out of phase

I'm trying to get a good recording, and have had a bit of help....but it seems that I'm out of phase.

It's the default Zoom H2 configuration at 90 degrees in the front of the mic. This is the result here:

STE-006.mp3 - File Shared from Box.net - Free Online File Storage

I don't know how to fix it...if anyone can help me out that would be great. I'm going to post this on the zoom forum as well.
 
Left gain available 8.9dB
Right gain available 2.9dB

Your levels are off. 6dB shy on the left channel / channel 1.

And you appear to be 50 samples fast on the left channel. According to audacity. Which can adjust those differences. Split the stereo track. Amplify the Left channel to -2.9dB to match the Right channel. Time shift the Left channel to start at 50 samples in. Then make stereo track. And it sounds better to me. More boom and twang IMO. Make sure that the selection toolbar is active and set to samples, not set to milliseconds or other things.

Not that it sounds bad by itself, but it can be made better. 50 samples is almost negligible, except for that Left and Right channels mixing thing, which you probably wont hear when wearing headphones. Otherwise not really a phase issue although the offset does affect phase.
 
The 6dB difference between channels is more obvious. And the math seems to suggest that (48000/50) would affect frequencies at or above 960Hz most. Which is worse than I thought. But is hard to notice on the original track given the gain difference.
 
Yeah I know it's off, I just wanted to post a straight recording. If you look at it in a phase analyzer it's very very wide, not at all like a regular xy pattern recording. I will do as you suggested with Audacity though and see what I can come up with! Or try and do it with Sony Soundforge, which is what I usually use.
 
I don't seem to have a way to change to samples rather than seconds. It should be in the view section, but I don't see it....do I need the Non-beta version?
 
You're going to have to zoom in (a lot) to get to shift by individual samples. Or just create a 50 sample silence and insert that before the left track. (and after the right track / make them match). When they're split of course.
