96 and 192 material is hi rez. Or Dsd recordings as well. I’m constantly doing shows with Infigo. So the reason I asked.
Umm, anything over 16 bit 44.1 (Redbook CD) is Hirez
24 bit 44.1......... 24 bit 48khz, etc and upwards are all hirez.
In fact, many official studio masters tend to be a higher bit depth, and not as a high a sample rate. To my ears, at least, the higher bit depth (24 vs 16, 32 vs 16) has always played a much bigger role in perceivable/audible improvements than the SR, while keeping file sizes manageable.
atmos mixes, 360 reality mixes, dts mixes, auro mixes, etc are all high rez.
