Re: A Meta-Analysis of High Resolution Audio Perceptual Evaluation Reply #50 – 2016-06-29 14:48:40 Quote from: ajinfla on 2016-06-29 14:20:54Quote from: jumpingjackflash5 on 2016-06-29 13:28:15those arguments are weak. Only last cca 20 years we have real technology that can do 24 bit and/or 48/96 kHz sample rates reasonably well. So no century wide research ....Believers believe we've only been able to generate >20khz signals for 20yrs??If you set the bar high enough, you can push forward the point in time when a certain situation was first true.For example, the AES Audio Timeline http://www.aes.org/aeshc/docs/audio.history.timeline.htmlsays "1996 - Experimental digital recordings are made at 24 bits and 96 kHz."I know that I was able to make high quality 24/96 recordings using B&K omni mics with flatish response up to 40 KHz and a reasonably priced pro audio recording interface card (Card Deluxe) ca. Y2k. I doubt that there are many who are aware of the various work-arounds that were used to gather experimental data > 20 KHz before then.
