“It is now widely, although not universally, accepted that “hi-rez” digital audio, with increased sampling rate or bit-depth, delivers improved sound quality. But it does so at large cost to coding efficiency. A 24-bit/88.2kHz recording requires three times the data rate of a 16-bit/44.1kHz alternative, and that ratio increases by further factors of two as sampling rate is doubled again to 176.4kHz and then to 352.8kHz, the sampling rate of DXD. While the progressive improvement in sound quality is welcome, it takes a disproportionate toll on data rates and storage capacity. Simply increasing sampling rate also fails to address head-on why it is that 44.1kHz and 48kHz sampling rates impose subjective limitations. Instead, sampling rate has become a proxy for resolution.”
