Please refresh my memory. I remember reading here (or in the old forum) several times, that you should not export/master to 0 dB level if you're going to later convert the file to mp3, but rather export to -0,3 dB max. This being due to slight level raise in the conversion, and possible digital distortion/clipping in the mp3-file. I expressed this view on another forum and I've been "challenged" to give some background to what I wrote. Is my memory failing?
