What type of nomalization does Soundcheck do? 2005-11-22 11:15:28 Is it peak normalization or RMS normalization? From what I have seen, it does not seem like peak normalization. It's more like a form of RMS in that it averages RMS energy over entire file, unlike Replaygain which averages over 50ms blocks. Does any body know what type of algorithm does Soundcheck use?
