/ W" C5 ~! Y; D+ a1 b/ G“In the September 2007 issue of the Journal of the Audio Engineering Society(Volume 55, Number 9), two veteran audio journalists who aren’tprofessional engineers, E. Brad Meyer and David R. Moran, present abreakthrough paper that contradicts all previous inputs by theengineering community. They prove beyond a shadow of a doubt, withliterally hundreds of double-blind listening tests at matched levels,conducted over a period of more than a year, that the two-channelanalog output of a high-end SACD/DVD-A player undergoes no audiblechange when passed through a 16-bit/44.1-kHz A/D/A processor. Thatmeans there’s no audible difference between the original CD standard(“Red Book”) and 24-bit/192-kHz PCM or 1-bit/2.8442-MHz DSD.”

通过严格的试验设计和双盲听觉试验对比,证明了SACD与CD间存在着不可闻的差异。这篇颠覆性的论文,第一次从专业角度,否定了发烧界和专业界共同认定的高采样率具有的优势,引起了广泛的争议。但是由于试验设计的科学性和谨慎性,反对意见没有任何充足的理由进行反驳。1 s4 n& x j* G6 p6 b) `/ G

但是,高解析度仍然是有理由的,只不过是有其他因素的帮忙。 |
