A High-Resolution Audio Primer

1 post in this topic

January's Industry Update included a report on a scientific article presented at last year's AES meeting, in which the authors used test tones and a modest audio system (albeit in an anechoic chamber) to prove that listeners can discriminate between high-rez and CD-rez audio. This is important because scientific evidence of an audible difference between high-rez and CD-rez music is considered weak by some, even as anecdotal evidence grows stronger by the day.

As I pondered this, I recalled a recent paper I'd seen in the Journal of the Audio Engineering Society but hadn't yet read. "High Resolution Audio: A History and Perspective," which the AES has made available free online, does precisely what the title says: reviews the history of digital audio beyond CD-rez and frames the issue of high-rez audio's audible superiority on the basis of the available evidence.
