Re: Opus 1.3-beta is here Reply #25 – 2017-12-26 17:16:25 Quote from: yourlord on 2017-12-26 15:48:57Quote from: punkrockdude on 2017-12-26 13:55:22Anyway, the track is full of artifacts which makes me wonder what age you are and if you have suffered any ear damage. I promise, I am not at all being rude but I felt I had to ask since the quality is bad and you say it is transparent to you. Regards.I winced when I saw him claim transparency at 48kbps as well because to me just about any full bandwidth music is obviously degraded at that bitrate. But, I can play 48kbps mp3 files for my wife and kids and they just can't hear the artifacts. I don't know what it is but they swear the files sound just fine to them. To me they sound like someone drowning kittens.I've come to believe that some people just don't have the capacity to detect/notice/care about audio faults and degradation. I'm kinda jealous because they can store 5 times the amount of music on their devices since it can be encoded at stupidly low rates. They can also get by perfectly fine on $5 garbage can quality headphones and think they are getting perfect fidelity.I'm in my mid-40's and played bass in a metal band most of my life, so my hearing is far from what anyone would call good. That being said, I'm the only one in my family that ever notices and complains when audio plays which is loaded with artifacts (it's really bad on Sling TV for instance). For me, Opus tends to get near transparency around 96kbps. Around 112kbps it gets to be essentially impossible for me to ABX. I know there are people who can, but that is about the level my ears and brain tap out.i have abx'ed Opus at different bitrates and i could not find a difference between 48 kbps and 64kbps, 80kbps, 96kbps, 112 kbps, and 128kbps for stereo music. i have done tests using quality Sennheiser headphones and mid range speakers. I do care about audio quality, and i have pretty good hearing.
