The compressor is a device that basically compresses the sound , that is, reducing the dynamics. By doing so it is possible to better “glue” the sounds together and in the end also raise the volume.
Each compressor functions differently, but common controls are threshold which decides at what levels the compressor shall start working, ratio which decides how much compression will be applied, attack and release which are timing parameters for setting how fast the compressor will work, and finally gain (or makeup gain) which helps in setting the level of the compressed signal.
