Event Horizon did a great job at raising the overall rms level of some tracks I was mastering. To be honest, I was expecting it to be good but I was very suprised to see it go beyond my expectations. I was able to push the tracks into the -9 to -8.5 rms range without distortion or losing the snare.
Within its limits, Event Horizon IS super-transparent. It’s not going to push it up into the -6 or -5 dB RMS territory that seems to be so popular today…but then again, it isn’t intended to. I am declining to provide armament to the loudness war.
