-14 LUFS can be the usual normalization stage for a lot of different streaming platforms.

Peak Normalization, alternatively, is the method of creating certain that the loudest components of an audio observe don’t exceed a selected dB worth. Making use of the Peak Normalization impact will increase the dB stage throughout a whole audio observe by a relentless quantity. As a result of the identical quantity of acquire is utilized all through the entire audio observe, the signal-to-noise ratio and relative dynamics relaxation unchanged.
