Does anyone know of any massive double blind study where they see what actual mp3 bitrate where people stop being able to tell the difference in quality?
I’ve tried and can’t tell the difference between any 320kbps and lossless.
There was one where the guy behind it went to massive lengths so people couldn’t easily distinguish the example files by other means than audio quality. Verdict was that people with more expensive equipment even preferred the sound of the MP3s (320kbps CBR). I think it was this one (Links to Parts 2 and 3 at the bottom.).
Somewhere else I’ve read that - for most humans - 256 kbps MP3s encoded with VBR-ABR using a high-end encoder are basically indistinguishable from the lossless original. Even at 192 kbps it’s still more hit&miss than it should be. But I don’t remember where I’ve read that.
Did you try on Bluetooth headphones? If so you won’t notice any difference because Bluetooth has very limited bandwidth and can’t really handle anything more than a standard MP3 (unless you have Sony headphones which use LDAC).
