A kick track compressed with a real analog Universal Audio 1176 Compressor, compared to a number of digital emulations : the Waves CLA-76, the Antelope Audio FET-A76, the Analog Obsession FETish, the Fabfilter Pro-C2 in Classic Mode, the JS 1175 and the Reaper Native ReaComp. All plugins have been gainmatched, the attack and release are the same, and the input/treshold has been set to get the same gain reduction.
