A Future of Digital Audio Watermarking and SDMI?

According to a report released last week by Cahners">http://www.cahnersinstat.com">Cahners In-Stat Group, a high-tech market research firm, the market for personal digital music players using audio compression technologies will experience a tremendous increase in growth through the next several years. Nearly $800 million in player sales are expected in 2003, spurred largely by widespread Internet access. The report also states that products in this segment will initially focus on downloading technologies like MP3, and over the next 12 months consumers should expect to see more features integrated into the players such as FM tuners, increased storage capacity, and security systems like Secure Digital Music Initiative (SDMIhttp://sdmi.org/">SDMI;).

A Guide to Ambient Music on the Web

Pauline Oliveros calls it "deep listening"—a way to pay attention to the sensual qualities of sound itself. Welcome to a world of music that defies categorization, that invites a listener to soak slowly into a deep and otherworldly zone. This music goes by many names: ambient, spacemusic, electronica, sacred music, tribal/trance. Alas, you'll often find it hiding in the New Age section. Unlike some fluffier New Age fare, good ambient albums can explore the deeper, more solitary spaces. At its best, ambient music can sensitize you to sound in unique ways. It can enlarge your listening space to cavernous dimensions, paint hallucinogenic sonic landscapes, summon primordial forces, or enshroud you in clouds of diffuse vapor.

A High-Resolution Audio Primer

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.

A McIntosh of a Different Color

McIntosh Laboratory announced its $6000 MS750 music server on May 30. The second music server in McIntosh's line, the MS750 incorporates a 750GB hard drive and integrated Web interface capabilities. McIntosh estimates that the MS750 is capable of storing 2700 CDs at full resolution, or about 12,000 songs.

A Must-Have Rachmaninoff CD

It starts quietly enough, with a simple falling-fifth motif, but the first movement of Sergei Rachmaninoff's neglected Piano Sonata 1 develops into a work of epic proportions nearly 40 minutes in length, with haunting melodies, massive dynamic contrasts, and lush, sensual harmonies.
