One person sent me email (Kevin Austin) with an excellent example, of a scratch in a record. He said, and I agree, that in such a situation it is very hard to pin down exactly where the scratch is relative to the musical score of music playing in the background. Even it this point doesn't stand up to exerimental scrutiny, I wanted to clarify at least what I had in mind. Hope this helps soften the breeze, Jont
