REQ: Isotonik Studios Multi Analyser Max for Live (Free)
They make little bigger version, called XL and delete free version from download section. If you have this please upload to AudioZ. Thx
"The fine folks at Isotonik Studios have whipped up a “Multi Analyzer” – a spectral analyzer that lets you compare tracks and view them at once. And that, of course, is actually what you’d want to do with such a tool, when finding mixing issues and the like. (Hey, Ableton – take note. This should be built in.)
You can route in up to four tracks and view their spectrum visually."
