The press release stated 16/44 was HIGH DEF and 24/192 was
ULTRA HIGH DEF. Truth in advertising, not so much. 16/44 - SD and 24/192 - HD. Don't actually know what ULTRA HIGH DEF audio is (384KHz) ???
"... High-
resolution audio, also known as
High-
definition audio or
HD audio, is a technical and marketing term used by some recorded-music retailers and
high-fidelity sound reproduction equipment vendors. It refers to
higher than 44.1 kHz sample rate and/or
higher than 16-bit linear bit depth. It usually means 96 kHz or 192 kHz, sometimes informally written as "96k" or "192k", meaning a
Nyquist frequency of 48 kHz. However, there also exist 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings that are labeled HD Audio. ..."
