the frequency analysis in Audition

Neither, really. In part it depends upon how much of a selection you've made and scanned. Sometimes it appears to look at the average of a section of the response and tell you that's what the 'overall frequency' is, but other times it appears to ignore the highest peaks altogether. But, it's very much dependent on what you've scanned. My observations over time have revealed that it is, to say the least, inconsistent. It must have an algorithm, but nobody's ever revealed what it is, which makes it an essentially useless figure.

The absolutely safest thing to do with these numbers is to ignore them altogether!
