As noted, I have read the sticky on this already, but I think my question is slightly different.
I have an SBD/AUD matrix recorded on an R-44 with the mics back at the board. The board is maybe 100ft from the stage. As I understand it, there is about a 1millisecond difference for every 50ft one is from the stage.
I hear very little noticeable echo, but certainly looking at the waveforms, the peaks on the aud look visually a touch "later" than the SBD.
The sticky describes lining up two recordings based on samples, which will not work for me, since both have identical numbers of samples given that I used an R-44 that recorded both exactly simultaneously.
My questions are:
1. What is the best way to "line up" the recordings - is there any feature that I'm not thinking of, or do you literally just have to zoom way in and eyeball the peaks?
2. Assuming that the answer is to chop some time off of one of them, should I chop the SBD or the AUD? Another TSer who I trust said to chop 2msec off the SBD- but this seems counterintuitive to me as the AUD is the delayed signal. Shouldn't I chop a tiny amount off of the AUD?
3. I have loved using Audacity and it has always met my needs, but now that I will be doing more 4ch work, is there another program that makes this much easier? (I'd especially like to hear from people who have tried it with Audacity and another program).
The most difficult thing for me, and the other thing that the very helpful post in the sticky didn't quite address, is again, how you can measure the differences. I am frankly not that comfortable trusting my ears to determine whether it's off (especially in this case, where the delay is not very significant given room size). I also am not entirely clear on the best way to measure the distance between two points in two separate 2ch stereo recordings. I see how to select, say, a length of music in one 2ch recording and have it tell me the length, but I'm not sure again, because the number of samples is identical, that that is apposite to telling me how far "off" the two samples are.
Any help much appreciated. I know there are always a lot of questions about this kind of stuff.
