Published studies relating MP3 bitrate to perceivable sound degradation? 2018-12-03 22:37:14 Recently, in a non- hydrogenaud.io forum I stated: "<0.1% of people would be able to distinguish competently-encoded 256kbps .mp3 from uncompressed, and only about 1% would be able to distinguish 192kbps. 128kbps is garbage, however."This was an educated guess. I expected it to be fairly straightforward to find actual studies about this. However, without exhaustive efforts (and without membership in certain organizations), I've only managed to find scattered data (some of which is ABX) and some non-peer reviewed "studies" that don't satisfactorily answer the question.Are there any published studies about this, peer reviewed or even just "reasonably competent"?Thanks.
