I recently began looking into phase correlation/cancellation issues. This got me looking into LOSER's "JS Channel Phase Meter" plugin and the JSFX code therein. LOSER uses the variable "phase" in this code. This is clearly a system variable as it is referenced without ever being initialized. And it is obviously some measure of phase correlation. But where is "phase" documented? What exactly does it measure? Why does it vary with his "Check Interval" slider? I don't find anything in the
https://www.reaper.fm/sdk/js/js.php documentation on "phase". More generally, where does one find documentation/resources for the audio concepts in JSFX (i.e., beyond just JS syntax and basics)? [Maybe this should be in newbieland forum but I didn't see any JS Qs in there.]
