How exactly does software (windows mixer, players like foobar, etc..) volume control work ? Is it the equivalent of replay gain or normalizing ? or is it more "electronic" or "hardware" than that ?
Thanks. |

It can be approximated by normalizing. No analysis is performed on sound to determine percieved loudness; It simply multiplies the played back samples by a constant number.
