Re: Subjective Tests Indicate High-Resolution Audio Offers No Benefits Reply #25 – 2016-03-15 04:03:43 Quote from: GUTB on 2016-03-15 00:16:33Since some people on this forum hold a certain reverence for ABX testing, I decided to play around with it. I know that doing this isn't going to change anyone's mind, and I will be just be accused for cheating if I did "pass" ABX testing anyway so it's literally a lose-lose situation. But still, I'm interested, the tools are easily available, and following some famous successes at ABX-ing high-resolution audio, I went and downloaded the ABX music set from AVS -- I didn't read a single post on that thread, just scrolled down to the download link and clicked it. I didn't cheat in any way.Going into this, I knew it would be tough -- I tried A/B-ing a 24/96 vs 16/44.1 version of one track I had in my library and I simply could not tell the difference. A/B-ing the down-sampled DSD-256 file I discussed early in another thread was much more significant. Doing it blind with songs I have never heard before, I wouldn't be surprised if I couldn't hear anything at all. Now, this was a first run, just to kill an hour, so I didn't put the track through an extensive critical listening regime, I just stopped at a section I thought the difference was pronounced (symbol taps starting at 01:20) and took the test from there. Let me just say, the difference is SMALL. Very slight. It wasn't until half-way through the test that I thought I had finally nailed down what to listen for -- but at that point, audio memory was smearing things, so towards the end I was reduced to just going with my gut reaction on what I felt was that tad more open on the sound signature of the cymbals. I made these judgement on a 15 second snippet of the track, trying to determine them based solely on the symbol hits.Quotefoo_abx 2.0.2 reportfoobar2000 v1.3.92016-03-14 19:31:10File A: Just_My_Imagination_A2.wavSHA1: 2a913086b5e4c2fa052e643a2ad11c18ea598cffFile B: Just_My_Imagination_B2.wavSHA1: 654dcecc9137b29f980d8d28fd63b5470b4695ddOutput:ASIO : XMOS USB Audio 2.0 ST 2023Crossfading: NO19:31:10 : Test started.19:33:28 : 00/0119:36:19 : 00/0219:38:05 : 00/0319:39:33 : 00/0419:44:35 : 00/0519:45:22 : 01/0619:47:09 : 02/0719:49:28 : 03/0819:52:20 : 04/0919:54:22 : 05/1019:54:22 : Test finished. ---------- Total: 5/10Ironic choice of material for an unlikely failed test result.
