Let's say I have a kick track. I put a compression effect on it with settings: Threshold: -20 dB, Ratio: 1:4, Attack: 1ms, Release: 20ms, Makeup Gain: 0dB.
Since it's a compressor, I expect it co compress everything above -20db, and make the overall sound quieter, until I use a makeup gain. But, the actual result is that kick becomes much more punchy, and it SOUNDS even louder, even though the actual volume of the track remains it's value before the compression.
So, the question is: why COMPRESSING kick without makeup gain makes it sound LOUDER and PUNCHY instead of lowering the volume?
