I encoded an album, using various "common" settings: 256 CBR 320 CBR 256 Constrained VBR 320 Constrained VBR True VBR 110 True VBR 127 What the heck, I don't know which to choose. They all sound too similar. Even the so-called "CBR" behaves almost identical to the "Constrained VBR" as far as bitrate fluctuations. Apparently, that is just the nature of AAC. My initial instinct was use 256 Constrained VBR, match the maximum iTunes quality, and call it a day. But some people on the internets swear by the True VBR. What do you guys use?
