Wetenschappelijk bewijs: digitaal maakt meer kapot dan u lief is...

Hallo forum

 

Deze wilde ik u allen niet onthouden. Hij komt uit een wetenschappelijk artikel van een zekere Jospeh O'Connell, geplaatst in de Technology and Culture nummer 1 van 1992. Er is een dame geweest die heeft geprobeerd met harde laboratoriumtesten te bewijzen dat digitaal gemasterde elpees je draaitafel naar de verdommenis helpen. Leuke combinatie van heel erg interessant en complete kolder. Enfin, lees zelf, en lach u ziek.

 

Opposed on principle to any kind of processing that the popular press suggests might be "perfect," audiophiles are likely to resent digital audio and look for scientific arguments to discredit it. One attempt to establish some antidigital claims was launched in 1985 by Judith Reilly of Quinsigamond Community College in Worcester, Massachusetts, who claimed to have discovered that digitally mastered analog discs damage the turntables on which they are played. Her initial research purported to reveal a statistical correlation between the number of hours a phono turntable had been used to play digitally mastered discs and the constency of its speed. She proposed a causal mechanism in which ultrasonic spuriae, produced by digitization and recorded in the grooves, would propagate from the stylus to the turntable bearing, causing microcracks. She also believed that ultrasonic spikes on digitally mastered analog records "rotted the innards" of the electronic equipment through which they were played. What made her different from other "digiphobes," at least temporarily, was the scientific support with which she bolstered her claims, claims made in a variety of audiophile journals and accompanied by references to the literature of metallurgical theory and ultrasonic propagation, photographs of oscilloscope traces purporting to show ultrasonic spikes, graphs of turntable speed versus time, electron micrographs of turntable bearings, and reports of corroboration by independent testing laboratories.

Her claims attracted much notice, including the attention of several highend turntable manufacturers who tried to duplicate her results, but without success. Ultimately, Reilly's findings were dismissed when neither she nor anyone else could duplicate them. It was a noble try, remarkable for how well it used the rhetoric of science. Other attempts have been made, including one purporting to demonstrate a correlation between digitized sound and listener stress. All have attracted attention and impassioned devotees, but none could withstand scrutiny.

? Da's toch logisch???? nou nee, als we toch op de ironisch-seksistische toer zijn, zou ik eerder een essay verwachten over de rijen CD-doosjes waarvan de bovenkant zo stoffig wordt, maar waar je zo heerlijk met een vochtig doekje overheen kan. Probeer dat maar eens bij een kast met platen.

 

Zou digitaal geluid ook epilepsie veroorzaken bij sommige mensen, net als stroboscooplicht?

Niks vochtige doek! Daar krijg je alleen maar vegen en strepen van. Ik gebruik daar een simpele plumeau van
