commitment towards the development in the high-resolution audio segment by offering a slew of Hi-Res Audio products. Streaming services As of 2021, several music streaming services such as Tidal, Amazon Music HD, Deezer and Apple Music all have options to enable the playback of high-resolution audio files. Controversy Whether there is any benefit to high-resolution audio over CD-DA is controversial, with some sources claiming sonic superiority: "The DSD process used for producing SACDs captures more of the nuances from a performance and reproduces them with a clarity and transparency not possible with CD."—The Mariinsky record label of the Mariinsky Ballet (formerly Kirov Ballet), St. Petersburg, Russia, that sells Super Audio CDs (SACDs) "The main claimed benefit of high-resolution audio files is superior sound quality [...] 24-bit/96 kHz or 24-bit/192 kHz files should, therefore, more closely replicate the sound quality that the musicians and engineers were working with in the studio."—What Hi-Fi? "...music professionals with access to first generation data have widely reported subjectively better sound, and a meta-analysis of previously published listening tests comparing high resolution to CD found a clear, though small, audible difference that significantly increased when the listening tests included standard training (i.e., with experience in listening)."—Journal of the Audio Engineering Society, Volume 67, Issue 5 ...and with other opinions ranging from skeptical to highly critical: "If [the music business] cared about sound quality in the first place, they would make all of the releases sound great in every format they sell: MP3, FLAC, CD, iTunes, or LP."—cnet "Impractical overkill that nobody can afford"—Gizmodo "A solution to a problem that doesn't exist, a business model based on willful ignorance and scamming people."—Xiph.org Business magazine Bloomberg Businessweek suggests that caution is in order with regard to high-resolution audio: "There is reason to be wary, given consumer electronics companies' history of pushing advancements whose main virtue is to require everyone to buy new gadgets." High-resolution files that are downloaded from niche websites that cater to audiophile listeners often include different mastering in the release thus many comparisons of CD to these releases are evaluating differences in mastering, rather than bit depth. 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 audio at 48 kHz. One 2014 paper showed that dithering using
