[QUOTE="Nick Hickman, post: 26637, member: 556"] Re: Help me understand system limiting- setting it Hi Bennett, Not sure I follow. I haven't researched this properly, but I can't see how any conventional filtering in the side-chain could cause the limiter to accurately track excursion. Random example from a simple model: signal with just frequency F at some amplitude causes excursion X. Add frequency 3*F at equal amplitude in phase, and excursion goes down considerably below X. Switch frequency 3*F to be 180 degrees from F, and excursion goes up considerably above X. Would it matter in practice? Would a limiter with a filtered side-chain be "good enough"? I don't know (but I'll stick to HPF + RMS limiter for now!). But if anyone wants a project ...! Nick [/QUOTE]
