Let's quickly take a look at the levels calibration in a studio. We've explored the different paths an audio signal takes in a recording studio, from one piece of equipment to another.
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.
We have spoken about the audio chain and the different stages a sound signal goes through to be constantly transformed into what we need. Every stage receives an electric signal entry, it manipulates it and returns as output the result of the manipulation that has taken place.
