Have any of you pro-mp3 bods got a cd with a swept frequency tone on it ?
rip that to an mp3 and then play it back, the higher frequency end of the
sweep will be a dead giveaway ( anti-aliasing ? ). NB same happens on
portable cd players playing a cd eg Sony CDman ( which you'd think was a
good make ) because of the antijog feature the cd is spun faster than normal
and sampled into a buffer to give the laser time to recover if it gets
knocked, play a cd with a swept tone with/without the jog protection the
differance is amazing................
