DC Offset with Horns?
« on: November 10, 2011, 01:55:59 PM »
I know that horns create an odd looking wav form which is lopsided on the push side. I recently did a tape where I've got an 9 piece jazz band (8 brass, with a set of drums). The drums look normal, but the brass doesn't (so far so good). When I run DC offset, it shifts to where the brass looks less strange, but now the drums are offset, sometimes.

So in this instance, is it just not worth doing a DC offset? Does it actually improve headroom or is it a waste in this case? My gear is solid, so I'm not worried about electrical offset being created upstream. I don't think it matters, but if someone can confirm, I'd love to know.

I would say that if your signal chain does not normally produce DC Offset, you should leave it 'uncorrected.'

Check out this page:

Certain instruments produce asymmetrical WAV forms. It's not always DC offset.
Reality is merely an illusion, albeit a very persistent one.

that makes sense, just had a brain fart when I was working on it last night.

yeah, I knew lots of brass horns created this odd looking wave form when close miced, and izotope wants seems to to treat it as offset which is what threw me off.

Neat site though, thanks!
