The possibility to sample a signal and therefore to transform it into a finite togetherness of data made it possible for it to be manipulated through mathematical operations rather than electrical transformations.
This is undoubtedly the most important processor. The compressor works on the dynamic range Dynamic Range of the input signal and reduces its amplitude when it goes beyond a certain limit: this reduction is expressed by a ratio, for example 3:1.
By dynamic range we mean the interval, measured in dB (the dB varies depending upon the dynamics of the contexts we are dealing with), between the lowest value that an audio signal can have and its highest.
