[QUOTE="Michael John, post: 50590, member: 830"] Re: Which limiters are good enough? Hi Nick, I took a look at the images on the "other forum." I must confess I don't understand quite how to interpret the diagrams. It's not what I would expect to see from any limiter. But I often miss the obvious. :-) I've attached a diagram showing an simple example of the trends I expect from a dual RMS/peak limiter. (a) Shows a sine wave going from quiet, to loud (above limiting thresholds), to quiet (b) Shows (a) after going through the RMS part of the limiter. The limiter begins to engage at time t0 but takes some time to settle. When the input signal drops at time t2, the limiter takes some time to release. (c) shows the waveform from (b) after passing through the peak limiter. This example has no look-ahead. The peak limiter takes a short time to engage and settle (quickly after t0) and then by time t1, the RMS signal falls below the peak limiting and the RMS behaviour continues. Of course I've made some assumptions here including the use of RMS limiting first, then peak limiting to mop up anything the RMS limiter doesn't grab fast enough. (Some limiters run the peak and RMS stages in parallel and the combined gain is a function of the gains from both computations.) Best, Michael [/QUOTE]
