And that's exactly what's wrong. Why would they add a variable quality setting if they will just hardcode it with no option to the end-user? It just doesn't make sense. Hence, that PR should be merged, even if the devs think it doesn't improve anything at all. Well, it makes perfect sense to me because Speex resampler at Quality 5 setting is already overkill quality. The user doesn't really need to change that setting. And i doubt Opus devs will change that just to appease users' paranoia. Anyway... all this resampler paranoia got me curious so here's a quick ABX test just for the sake of testing : )foo_abx 2.0.5 report foobar2000 v1.4.2 beta 1 2019-01-07 22:49:40 File A: sample1-speexQ1.flac SHA1: 4c43030347b56331a98265420fc71d1d61fca6d0 Gain adjustment: -6.17 dB File B: sample1-SoXBest.flac SHA1: 7a939eac303badc0e6ee79edcd595613dc3d3e3c Gain adjustment: -6.20 dB Output: DS : Primary Sound Driver Crossfading: YES 22:49:40 : Test started. 22:50:11 : 01/01 22:50:42 : 01/02 22:51:12 : 01/03 22:51:42 : 02/04 22:52:14 : 03/05 22:52:43 : 03/06 22:53:14 : 03/07 22:53:43 : 04/08 22:54:14 : 04/09 22:54:43 : 05/10 22:55:15 : 05/11 22:55:48 : 05/12 22:55:48 : Test finished. ---------- Total: 5/12 Probability that you were guessing: 80.6% -- signature -- 214275c2580e7471bdc3280753c61b5bf38b9f9b So it seems that even Speex Q1 is enough to fool my 27 years old ears... and i really tried hard but simply failed to detect any difference. Note: to resample from 44100 to 48000 i used foobar2000 SoX and Speex components both by lvqcl. The original sample (sample1.flac) can be found here . That's all for today...
