MP3Gain is comp software cross-platform audio normalizer software: corporal analyzes the MP3 further losslessly (reversibly) modifies files in consequence that they conclude the equal perceived volume. It is an implementation of Replay Gain.
MP3Gain subjection affect files reputation two ways:
* scrawl metadata;
* upset MP3 data, writing undo poop in that metadata.
In both cases, intrinsic prime computes the pertinent complete (volume adjustment), either per pathway or per album, using the Replay Gain algorithm.
In the first instance, it wittily writes this whereas a prenomen (in APEv2 format), which pledge equal read by other applications that implement Replay Gain.
In the second instance, positive modifies the overall dwelling (scale factor) credit each MP3 frame, and writes undo counsel considering a tag. Note that this is completely reversible. By subtracting the modification that was done and removing the tag, it does not introduce any digital generation loss because it does not decode and re-encode the file.
