I recently did some ABX tests of music encoded in FLAC levels 0-8.
To my surprise I could tell the difference more often than not. Yet I couldn't help but wonder, what does this really prove? It seems that if an audible difference exists between two tracks, that difference wouldn't necessarily indicate anything as to which track is of higher quality, but rather, that those two tracks are merely different from one another... Am I missing the point in all of this? |

I concur with the first response you were given, btw. Telling us that you can tell an audible difference between flac compression levels brings your methodology into serious question.
-------------------- Everything sounds the same until it is proven otherwise.

Telling us that you can tell an audible difference between flac compression levels brings your methodology into serious question. To clarify, I didn't mean to say I could tell the difference between FLAC 0-8 more often than not... Rather, that of some of the tracks that I tested, which I had previously encoded from the same source (using the same FLAC 1.2.1 codec), difference to my own ear was indicated to me (and only me) by a probability that was statistically significant. HOWEVER, I did NOT mean to start some sort of argument as to the means by which I performed the tests or for that matter, anything to do with my testing at all (I probably shouldn't have even mentioned those tests to begin with, it was just for context). I was just trying to frame a much more general question, pertaining to the difference between two tracks sounding different as opposed to one track sounding better than another... My apologies if I came across otherwise! |
