 Most early papers using blind listening tests concluded that differences are not audible by the sample of listeners taking the test.Blind tests have shown that musicians and composers are unable to distinguish higher resolutions from 16-bit/48 kHz One 2014 paper showed that dithering using outdated methods (rectangular unshaped dither, rather than the industry standard triangular dither) produces audible artifacts in blind listening tests.Since the Meyer-Moran study in 2007, approximately 80 studies have been published on high-resolution audio, about half of which included blind tests.
