Topic: Software/plugin for cross correlation of two files?

[poorlyconditioned]

Does anyone know of software or a plugin that does cross correlation of two WAV files?  That is, take two waveforms as input and return a waveform as output, where the position in the output waveform is the correlation of the two files with a particular offset.

I'm thinking this would be a good way to do matrices (align sbd + mics).

Thanks,

I wonder the same thing...I dont really like any of the tricks/hacks that we have to use.

I havent experimented with reclocking each signal yet...can you do this with a computer? Im not even sure there is such a thing as reclocking...

And my experiment with using the same clock failed...but I might try it again. There were some clicks in one of the recordings...so maybe some samples were dropped and caused drift...

Theoretically, let's say if both sources were identical (which of course they won't be), you could invert phase on one of them, then sum them together to get a flat waveform right? Makes you wonder if you could do the same thing with two sources and then just play with the mix until the waveforms are as flat as you can get them. My guess is that wouldn't work for shit, but your question made me think about that.

That said, I've had a lot of success in Vegas by syncing the head of the file (initial sync), then stretching/compressing one track at the end of the file until the tail is in sync (fixes drift). I have to do this when I sync to video all of the time, and once I get it nailed, the entire set stays in sync pretty well. But, we all know that stuff, you were asking a different question...

SparkE takes one of his tracks, goes line out of that recorder into the line in of the JB3(that contains the other track), trying to keep the JB3 at the same temp that it was in the club...this helps in terms of clocking/alignment..
