Shai is correct, again, on this topic. And, once again, myth-amplification must be quashed. Please read: http://www.aes.org/aeshc/docs/aeshist/standards.hist/digital.standards/history-of-aes-digital-audio-eng-standardization.html Also see my ARSCJ article, "The Dawn of Digital." There were many different standards early on. The 44.1/16 standard was heavily lobbied by the Japanese videotape machine makers (Sony and JVC mainly) because that is what fit within PAL, NTSC and SECAM framerates on standard videotape machines, thus allowing for a cheap, available and (somewhat) reliable storage medium for digital audio information. Proprietary (and higher-resolution) systems such as Soundstream and 3M used very expensive storage systems, not practical for industry-wide adoption. Apparently, some people need a neat little marketing myth to "explain" how the CD was developed. I don't understand this. The format was developed by engineers, as an evolution of PCM digital audio developments mainly coming out of Japan (and mainly out of Sony, in the case of the CD) and optical-disc manufacturing and playback technologies mainly developed by Philips, evolving out of the analog-optical VideoDisc medium. There are logical reasons, based on technology, for all aspects of the CD. Crazy edicts like "it MUST fit my buddy Karajan's Beethoven 9th" never came down from higher-ups. However, there were certain marketing edicts. The 5" size probably was bandied about early because of car dashboards and retro-fitting standard-width radio/cassette units (although most early car CD systems I saw had an external disc "changer" or drive chamber that was highly mechanically damped; I recall the second-generation being single-disc players all-in-one in the dashboards, still mechanically damped). For what it's worth, my father and a few others in the AES were actively and vocally critical of the 44.1/16 standard (in retrospect, I think what my father was hearing on the digital-master LPs was jitter, which was an inherent flaw in the early PCM systems), but they would never win the day because of the compelling argument of off-the-shelf videotape recorders as the primary mastering and storage machines. There's also the fact that Sony got the PCM-F1 out into the market and the middle level of recordists (high-grade amateurs, small record labels, higher-grade broadcasters) discovered how much better those things sounded than their Otari and Teac reel-to-reel recorders. The buzz in the marketplace was "digital is better" and the record companies were desperate for something to pull them out of the post-disco market slump (as much as I and others may love the punk/new wave music of that era, look at sales figures and you'll see that it was not a savior for any record company). All forces were lined up to strongly back what Sony really wanted -- a digital audio standard reliant on their hardware, their expertise, and their software. Philips greatly benefitted by selling playback hardware and leading the global market in digital software. And yes, artists like Karajan benefitted from the CD, but it was not invented "for them." -- Tom Fine ----- Original Message ----- From: "Shai Drori" <[log in to unmask]> To: <[log in to unmask]> Sent: Wednesday, September 10, 2014 6:02 PM Subject: Re: [ARSCLIST] CD time limit - Beethoven > Sorry Clark.
