"Several recent researches, however, had argued about subjective
difference between sounds sampled at 44.1kHz and 96kHz. What can make inaudible
ultrasounds audible is not known."
and then tested on 4 students. It's like, if man can hear presumably
20Hz->20kHz, why do I sense being hit by a hammer 2x each second? It's
only 2Hz!
I have my doubts, but I think current mastering engineers
should put a bit more efford in trying to fill the <21kHz spectrum and
keep the recordings as clean as possible. In my everlasting seach for
artifacts, the most inperfections I find are there right in the source
material. (poor samples, bg noise, clipping, overamplified distorted
audio).
I see not much practical use in 95kHz sample rates, and percieve it
only as a means to get a new copy-protected & patent-crippled medium on the market.
