That's a goo way of doing it. I don't use Adobe Audition with JAWS. I think Audacity would work nicely for this purpose. The only problem I found when mixing two identical recordings on each channel, they turn into moo, instead of being panned out like they'e supposed to.

Thanks Green Gables Fan and camlorn for replying.
Your explanation camlorn seams very logical and it makes sence.
Yes I am thinking to get a stereo microphone but I don't know which one.

Hi,
Sorry for bumping an old topic, but was browsing audio stuff on here and couldn't resist.
I checked out the posted clip and did some rough work on it to try and keep the channels in sync. I went to the end of the file and saw the left channel was ahead of the right. By deleting approx. 800 samples or 0.018 seconds from a spot very close to the end on the right channel, the stereo image was much more cohesive. The 800 samples isn't an exact figure of how far out of alignment the channels are, it was just something I tried that worked. I don't know if it is even possible to scientifically measure, down to the sample level, how far off alignment channels are, especially when the two sources are far apart. It's easier to do with more closely based mics but these were wide apart it seems. Or at least the stereo image suggests width. Anyway, let's do some math:
If it takes the left channel approx 70 minutes to get 800 samples ahead...
800/70 = 11.43 samples per minute
11.43/60 = just shy of 0.2. That is a very rough sample rate difference between the two.
Just as an experiment I told Gold Wave to pitch the audio on the right channnel in such a way as to make it 0.018 secs shorter than the left. In theory this would at least minimize the drift, even though I had not the means or patience to try to scientifically measure it. I wasn't expecting much. But to my surprise it actually did preserve a nice stereo image throughout, without any audible artifacts that I could hear. This is exactly why interpolation exists... to allow a guestimation of the waveform between the sample points.
I suspect there are automated solutions that can do this, though whether they can cope with gradual drift and to what extent I don't know. I do know azimuth correction is available to fix some channel alignment issues particularly with tape, but I don't think that's the same as what we are seeing here where the channels drift gradually because of very slightly differently timed clocks.
I was actually going to try this kind of recording with two IPhones to see how the mics would sound in stereo, just for the fun of it. Thanks for trying this first so I know what I'll potentially be in for if I get bored enough to do it myself. Lol

I did not save it, but now that I know what I did I can do it again fairly quickly. How shall I send it? If you don't respond or don't have a preference I will most likely try to share a Google Drive public link.
