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. ![]() Unfortunately that happy medium isn't so medium and isn't so happy these days.Mp3gain Description If it's too loud then it compresses everything else and makes the recording sound too quiet, so a happy medium is found. These sound a lot quieter than 1 and about the same as 2 but convey a much more accurate recording than either.Ĭlipping is inevitable because no matter how you set your recording gain, something's going to be "too" loud for 16 bits, for 24 bits, for 32 bits. Recordings that clip sometimes, but rarely. Recordings which SHOULD clip constantly, but have actually been attenuated so they don't fill the range available. Recordings which clip CONSTANTLY to the point of becoming static (Ever heard 'Californication' or indeed anything else by RHCP?) This is the overwhelmingly most common approach.Ģ. There are three kinds of recording in this world:ġ. If the value is the highest it possibly could be, chances are good that the input signal was even higher. Instead, what we do is count how often we hit the maximum that 16 bits provides (for the purists, it's then halved because the same clipping event will cause both a positive and a negative maximum). 16 bit audio has one hell of a dynamic range, but it's not infinite. Strictly speaking, digital audio cannot clip because it already is clipped. The MAD decoder does it and ReplayGain will handle it too.
