Συμπληρωματικά προσθέτω το παρακάτω:
Normalisation is a process that looks for the highest peak in the sound file, and then raises (or lowers) the level of the entire track so that peak matches a specific level. For example - say you under-recorded the whole take, and the highest peak is -48 dBFS. If you Normalise to -6dB, the algorithm works out that the entire track requires a boost of 42dB. This is an extreme case, where there isn't enough gain on the fader to do this in one step. It's a desperate salvage operation - not good recording practice.
Or - if a mastering engineer is given a stereo mix where the highest peak is -0.1dBFS - there is no headroom for safe processing. The ME might be forced to Normalise the file down to -6dBFS. Of course, this could be done by moving the fader, so they probably wouldn't Normalise.
Το gain απ' την άλλη απλά ανεβάζει το volume ακριβώς όσο του πεις.
Δεν κοιτάει peak ή οτιδήποτε άλλο.
