How would I correct the timing in post?

Select the tracks you wish to shift, then slide them along the time-line until they are correctly aligned with the others.  You may need to unlock the channels or tracks in your DAW software to allow this shifting movement.

Huh, never did this before...but never felt the need either.  I will check this out with either the last or the next recording that may need shifting.  Thank you.

I would do it in the post!!  Super easy and I always shift mine some.  If you zoom in on a peak it is really easy to line them up.  There will always be a bit of delay.

7.5 to 30ms ain't shit for delay, good luck with that 744T, buddy.




Remember to to delay the video too, if'n you're doing it LIVE.  Have fun and make great tapes, nak700s.

Both sources are synched to the same clock. Set levels appropriately for each source and line 'em up in post. Piece of cake. Takes all of about 1.5 minutes once you get the hang of it...

Audacity, for example, has a Tracks - Align Together command.  Select tracks, click and done.

I have done it on the deck a few times with some success but almost always end up doing it by ear in post.

Speed of sound
343.2 meters/second
1125.7 feet/second
1.125 feet/millisecond

The math is a good starting point but getting it tight by ear is crucial. I use the estimated feet from the source then start to go forward and back 1 ms at a time until the comb filtering in the bass frequencies gets tight. You will know it when you hear it.

The phase scope in Wavelab helps too. Not sure why but different sets recorded with the same gear in the same place an hour apart from each other have needed different amounts of delay to sound right...
