Comment 2 for bug 642268

I agree with Vittorio in this case. Adjusting the songs so the peaks are similar is not how ears perceive loudness. See here for more info: http://replaygain.hydrogenaudio.org/calculating_rg.html

I'm opposed to implementing ReplayGain analysis within Mixxx itself, as I think this is outside the scope of Mixxx. The ReplayGain should be measured and applied when the file is encoded in whatever format it is in. The standard FLAC encoder does this, for example.

I'm assigning this to myself since in my TagLib branch I will implement loading ReplayGain values from all the metadata formats (APE, ID3v2, Xiph, MP4) and then apply the replay-gain at track load time if it is present.
