When you reduce the dynamic range (compress) you bring up front what before stayed in the back which translates into a bigger, more solid image. |
Just to clarify a little further, compression does not make the soft parts any louder, as it only acts on the parts of the signal that exceed the threshold (i.e., the loudest parts). By reducing those peaks, the overall dynamic range (and loudness) is reduced and, therefore, you can bring the overall level up before clipping occurs. Some compressors have a make-up gain which essentially does some of this for you by calculating the overall decrease in loudness caused by the compression, and compensating for this loss by increasing the compressed signal's loudness by the same amount at the output stage. Either way, it's actually the raising of the overall level that brings the quieter (i.e., uncompressed) portion of the signal forward, rather than the actual compression of the louder parts, that increases the perceived loudness and makes it sound "thicker."
