apparently it's not just 44.1 kHz that's inadequate, it's 48khz too
http://www.dolby.com/uploadedFiles/Assets/...ormance.PDF.pdf whistled version: http://www.stereophile.com/content/dolby17...apodizes-truehd The technical gist is that Dolby's using Meridian's 96kHz upsampler and 'apodizing' filter, which they say masks pre-ringing. (which apparently is commonly audible using 48kHz SR, and apparently can be masked without introducing frequency response or phase artifacts that are at least as audible -- right? Because otherwise there would be no point to this...right? ) Btw, my respectable but not-boutique-high-end AVR already upsamples everything to 96kHz (in order to apply DSP) so again, WTF, Dolby?
