Talking about CD level audio (16bit; 44,1 kHz; Stereo) The only source I could find regarding that was: http://wiki.hydrogenaud.io/index.php?title=Opus#Music_encoding_quality But that

Everything above 96kbps on that table is speculative, as the highest multi-participant listening testing done was at 96kbps. Here's the results from that test, if you're curious: http://listening-test.coresv.net/results.htm As you can see, at that rate Opus ranged from slightly perceptible to imperceptible. Also importantly, note how few of the donors were able to give significant results on most tracks. This makes a 128kbps or higher test impractical as there would not be enough listeners capable of...
