In Reply to: Analog -to- 24/96 PCM -to- analog is transparent to human hearing posted by Feanor on February 6, 2007 at 07:32:51:
It's been years since I followed the psychoacoustic literature in JASA, but I think your supposition is correct about insensititvity to a correctly performed conversion process.And it serves our auditoy process well to be insensitive to many distortions, so we can generalize over disparate conditions. Think of our auditory system from a teleological perspective. Except for binaural phase for locating a danger, for example, phase perception is simply not important to our survival, and a few centuries is insufficient to evolve sensitivity to such. OTOH, sensitivity to acoustic level and frequency content is obviously critical to survival -- who can we eat or who is aiming to eat us, where are they, how close?
