It can normalise the gain on a single mp3, or work out the &#8216;normalised&#8217; gain on an entire album (or repository) and tweak each mp3 to bring it in line with the others.\u00a0 To be honest, I didn&#8217;t even know mp3s had metadata you could tweak to do this, so it didn&#8217;t occur to me this was an option.<\/p>\n<p>I ran it\u00a0 across the albums in question, and it decided they were consistent within themselves. Rather than run it across the entire repository, I increased the gain by a set 3dB, and then after listening to the resulting output, another 3dB. Maybe one day I&#8217;ll back up my mp3s and run it across the entire repository.
