What happened to Hi-FI?

If it's audible it's either at such high frequencies that the human ear cannot hear (Over 15-16 kHz), or it's masked in the low and mid range frequencies also. If it's in the very high range, a LowPass filter comes right to my mind, so that's probably not the case. If it's in the mid/low range, it's not a perfect replication of the original source, and HI-FI freaks tend to have very very long polemics about is or is not such a format usable Smile

. If it's in the low or mid range, truth is, that cannot be removed in any way without the source data so that would really be the perfect protection.

But!

The whole thing sounds weak though:

yeah, if its inaudible its easily removed with a high (or low) pass filter. doing it digitally you're only going to lose what you want to lose, so youll end up with a better copy than the original (none of that inaudible "noise" on the soundtrack)
