[QUOTE="Nick Hickman, post: 50501, member: 556"] Re: Which limiters are good enough? Hi Silas, There's no shortage of analogue compressor/limiters where the limiter is a clipper that clips off the signal until the compressor has chance to ramp down the gain. If you integrate a delay you can, as you say, "look ahead" and start ramping down the gain early, so avoiding the clipping. This is a function of attack and release times. A compressor/limiter is essentially a fast-reacting hand on a fader: it ramps down the gain while the signal is over threshold and then ramps it back up again when the level drops below threshold. The appropriate attack time is usually a function of the lowest frequency within the bandpass (so it reacts quickly but doesn't audibly distort the waveform). I don't think there's a shortage of loudspeaker processors with RMS limiters as this is usually the primary requirement for loudspeaker protection. If you're lucky enough to be using an amplifier rated more than 3dB above the driver's power rating, you might consider a peak limiter as well. BTW, I'd second Evan's recommendation of the DCX2496 as a budget loudspeaker processor. It includes a combined RMS and peak limiter. Nick [/QUOTE]
