Logic Pro X 10.1 Compressor

  1. I am using the Platinum Digital model on a vocal speech track. I always had the impression I understand the principle how compressors work but I’d like to give you this example where I am totally confused how the LPX compressor works the way I see it on the graph or output level:
    Ratio=30:1, Threshold=-30dB, Attack=0, Make Up=0. Speech is around -20dB with one peak at -8.7dB. Normally the compressor should reduce everything to an output level between -30dB and -29dB, right? It should compress the range -30..0 to -30..-29 because of ratio 30:1. In practice there is no audible difference anymore with ratios of 3:1 or higher. How can this be? Compressors work on peak db, not rms, right?

    1. Hi Sven, in Logic Pro X’s compressor you can switch between peak and rms by clicking on the “side chain” button on the right. This function is available only on Platinum Digital because the other circuit types follows the hardware models. Also note that, by default, Platinum Digital works in rms so this is probably why you couldn’t hear the right effect on your vocal tracks. Try to switch it to peak and let me know if you need further help.
