![]() ![]() ![]() The method mp3gain uses to determine the desired volume is described at (link to URL ). If you only want to print the recommended gain change (and not modify the file at all) you have to use the -s s (skip tag) option. If none of these options is given, only a tag denoting the recommended gain change is written to the file. Mp3gain actually changes your file's gain only when you use one of the options -r, -a, -g, or -l. no support for a special tag or something similar is required. Also, this works with all mp3 players, i.e. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding. Also, the changes mp3gain makes are completely lossless. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. Mp3gain does not just do peak normalization, as many normalizers do. Mp3gain can analyze and adjust mp3 files so that they have the same volume. This manual page was written for the Debian distribution because the original program does not have a manual page. This manual page documents briefly the mp3gain command. ![]()
