16500 Hz lowpass test 2018-04-25 17:33:08 As requested in https://hydrogenaud.io/index.php/topic,115869.new.html#info_956270I am using a sample from "Perdition City" album by Ulver which contains very loud ~18kHz tones.My log:Code: [Select]foo_abx 2.0.4 reportfoobar2000 v1.4 beta 112018-04-25 19:23:21File A: original.flacSHA1: e13538feeed7099972334ae94da4a400af82e88eFile B: lowpassed.flacSHA1: 76b6e79649d86c8e77c71a00faa1196a58472af4Output:WASAPI (push) : Built-in Output, 24-bitCrossfading: NO19:23:21 : Test started.19:24:46 : 01/0119:25:12 : 02/0219:25:22 : 03/0319:25:31 : 04/0419:25:40 : 05/0519:25:48 : 06/0619:25:56 : 07/0719:26:08 : 08/0819:26:08 : Test finished. ---------- Total: 8/8Probability that you were guessing: 0.4% -- signature -- 38880f32382b49c5f24b3c7ae7af53e431d2643aI am leaving it at 8/8 as it is really painful to listen at the volume where I can confidently hear that tone. :/This was surprisingly hard, and I found that I hear it now only with my left ear (used to be able to hear it with both ears back in the days).If someone wants **/16 then I'd rather give up. I think someone younger will do this test a lot easier if they want to prove the point that sometimes there is some noticeable content above ~16kHz. And I'm apparently near the point of being too old to be able to do this.
