Last nite, I mixed a drumset down to two tracks.
I sent 16 tracks individually out of vegas, and recorded 2
back in as a stereo pair of the entire drum mix.
Once the recording was finished, I lined the stereo pair up
with the original kick drum.
I lined up the very first kick hits then looked at the very
end of the file
The kick drum in the mixed tracks was 3 miliseconds AHEAD
of the original!
OK, 3 ms doesnt sound so bad, right? and a marvel of
engineering, especially on a 5 minute 30 second file
But rest assured, 3 ms is WAY more than enough to cause a
flangy filter across the whole recording, not to mention,
where do I line up events? now everything at the end will
flam, if I set the beginning right
You would think maybe I would just stretch the audio, and I
was preparing to do just that
Just for safety's sake, I looked at the MIDDLE of the file,
to make sure that the difference in time between the kicks
in the middle was somewhere between half the difference
from the beginning to the end....
IT WASNT!!!
In the middle of the song, the difference was 5
miliseconds!!!!
Ok, so what went wrong here? It played slow, then fast?
What happens if I keep going around in the file, checking
times, am I going to see more speed ups and slow downs?
Any suggestions?
I suggest SAMPLE ACCURATE SYNC
