Using compressors to avoid output clipping says "I would suggest using a full-range (-90 dB to +24 dB) RMS compressor", but the compressors don't go to +24 dB, they only go to +6 dB:
Used this way, it only limits for 6 dB and then gives up:
But the headroom of the internal representation is 16.0 = +24 dB right? So it's not possible to directly limit +24 dB down to 0 dB using the compressor block? We have to attenuate by -18 dB before the compressor, limit to -18 dB, and then boost back up +18 dB so that the limited value lines up with the maximum output of 0 dB? If I do that, then it behaves similarly to the Limiter block. Is that how these peak compressor blocks are meant to be used?
