Hi folks:
Back in the 1970s I recall reading a most interesting article on how much headroom was required over nominal level to avoid clipping. The author reached the conclusion that 17dB would be adequate a large percentage of the time.
Regardless of whether the author was correct (that's an entirely separate thread), my question is, who wrote the article? For years I remembered, and told people, that it was Robert Cordell, then with Bell Labs. But I've recently exchanged e-mails with Mr. Cordell, and he said he remembers the paper but didn't write it. Cordell wasn't sure who did, but suggested Richard A. Greiner.
I tracked down Prof. Greiner, now retired from teaching and living in Wisconsin. He also recalled the paper, and also said he didn't write it, and doesn't remember who did.
So who did write it? I need a citation for my class. If it was in the JAES I'll be able to dig it up with an afternoon of browsing at the Washington U. library, but I'm not sure it was; it may have been in Audio, which isn't archived anywhere around here. (It was, but in the mid-70s students began stealing the magazines and they had nothing to send to the bindery at the end of the year.)
Can anyone here help? Inquiring students and faculty want to know!
Peace,
Paul
