Must I ABX without any equalizer tweaks? 2005-10-16 21:28:45 Or, to be more specific: Can I call a certain encoding non-transparent if I can only hear the difference when I adjust the frequencies to my liking on the EQ?The background to my question is this: I have a song (by Conjure One - "Sleep") which is dead easy, even at -b 320 (using Lame 3.97b), to tell from the original wave when I play them in winamp where I have the bass and treble turned up. (The lowest frequency at +12 and the three highest at about +6 - it's the higher freqs that give the mp3 away.) However, when I decompress the files and try to ABX them in WinABX (where there is no EQ, obviously) it is very difficult (impossible?) to tell the difference.I would like to argue that something that doesn't sound like the original in my listening environment, and with my frequency tweaks, isn't transparent. Is that reasoning reasonable, so to speak?
