Akira is 192khz, why not other movies?

BD4Life stated the case for 192kHz sampling really well above.

yes...let's please end this confusion once and for all. 192kHz sampling means 192,000 "time slices" or samples of the waveform, whereas typical redbook CDs are sampled at 44.1kHz and typical BD audio at 48kHz (or 44,100 and 48,000 times per second respectively). This means for every one sample at 48kHz you are getting four samples at 192kHz, which would be more data per second and a more accurate representation of the original analog waveform. The stream also takes up roughly 4 times as much space on the disc too - less with lossless compression.

These numbers have absolutely nothing to do with audible frequencies, i.e. the pitch of sound (highs and lows).

I may rent this disc just to hear the audio.
