Distinguished Frequencies


Interesting Findings:

At the October 2019 Audio Engineering Society convention in New York—just concluded as I write—Yuki Fukuda and Shunsuke Ishimitsu, both of Hiroshima City University, presented results that show quite clearly that listeners can distinguish sounds encoded and reproduced at different sampling frequencies.

Let me guess. Scientifically controlled double blind testing, right? AES, who else?. Oh, brother!
Listening to white noise seems like a strange choice........I wonder if the noise sounded better at higher sampling frequencies?

White noise seems like a smart choice to me. The purpose of the test was to ascertain if there was an audible difference between different sample rates, not whether any "sounded better."
So, one thing that I've noticed, and not sure was taken into account: Different DAC's perform differently at lower resolutions.

With the Mytek I'm listening to right now i cannot tell Redbook vs. 96/24.

With an ARC DAC 8 I could.

It would be really interesting to see if this research further delves into exactly what the cause is.
