Hi!
Last Saturday I recorded 4 bands with:
AT853 > BB > Microtrack 2496 (44,1/16 Wav) (powered with external battery 4xAA thru usb)
1-2-4. recordings are okay. (Even 4th is alright what ended as 0 byte because MT shut down when batteries died, I tested the card with chkdsk and imported to Goldwave and the result is perfect).
(I already edited this wav, but I checked the original file too, and it is inverse in the same way, so its surely not I edited something wrong post.)
Only the 3rd set is strange:

Looks like one channel is just the opposite? What could cause this?
I see I can make inverse in Audacity, but what would be the right method to save out a good track? It would be a good mono sound at least...(Now it sounds really high, no low, no bass)
Thanks!

Could it be a jack plug wasn't in properly? The thing that triggered that thought for me was you saying there was not much low end and I had something similar at the weekend - read some posts here and someone had commented that a partially inserted plug had caused a loss of low end, which could well have been the case with my recording as I had a few crackles.
Not sure whether this could cause the inverse waveform, but it is kind of believable if the plug and socket contacts weren't correct.

Hm, yes. That always could happen :(

Ok, invert done and now its clear that the waveform is perfectly the same in whole 1 hr length.
So I wonder if badly plugged jack can cause that the 2nd channel record the 1st channel's invert?

If you insert a 1/4" TRS plug in only half way into a balanced input this can happen. Because if you insert the plug half way the Tip of the plug will contact the Ring of the jack.

That looks like what happens when a single point mic is plugged into a two channel (l-r stereo) cable. The result is mono but with the right channel inverted.
Not saying that's the case here but Chuck's guess is probably what happened (or something like that - cabling mixed up or not fully connected).
-
Yes, so must have been the jack not plugged in perfectly. The new recordings are ok, no problem since that.
Well, I know one more thing now...
Thanks all ;)

You're in good company. My first time out with my M-10 the 1/8" cable from my preamp came unseated at the line-in on the recorder. And thus, the internal mics on the M-10 were active.
Good news: I got a recording.
Bad news: I now know what the internal mics on an M-10 sound like buried in a rig bag lying on the floor of the Stone Pony and covered by a layer or two of towels acting as protective padding...
Hmmm, maybe I should upload the recording to Dime as a goof... :lol:

That's such a test that no one else would ever make! We should be thankful for you! :D
