I frequently encounter arguments about what a technical term means.My nr. 1 on the argue list is: 'headroom', followed by 'gain/ volume', 'distortion/ clipping' and 'loudness'.It would be nice if some of the top techies on this site can agree on the use of these terms, put their name under the article to be used as reference by all them non or semi techies, so it can try and diminish the constant barrage amongst posters.
