Hi All,

I've been corrected before on this site for making the statement: "I can tell the difference between an MP3 and lossless". I've never ABX'ed myself but I was wondering if there has been a statistically significant (with regard to population) ABX study done with (say) Lame insane vs. Lossless?

Clearly for myself it makes more sense to do a personal ABX but I was wondering in general about the population.

I searched manually through the posts in this forum (since search seems useless for the term 'mp3') and didn't see anything.

Thanks for help,

ss.

"lossy vs. lossless ABX" doesn't make any sense. You simply ABX lossy codecs against the original, be it a wav file or a losslessly encoded file. The term "lossless" here is irrelevant. ABX tests of various lossy codecs at various settings have been made several times, search the forum (just don't search "lossy vs. lossless" specifically, because of the reason I just gave).

Come on. I think every single person who read my post understood what I intended here. You are arguing semantics instead of giving information.

try searching for lossless lossy abx


As noted in my original post, this doesn't work because the (in my opinion insanely dumb) search restrictions on the board prevent searching for any term shorter than 4 characters.

You couldn't do an accurate statistically significant test with average users because they'd all be using different (and much of the time lousy) equipment.


I guess the study that I was looking for would use standardized equipment for all participants thus eliminating this factor.

Thanks for all the information... but I still haven't seen a link to an actual study.

If indeed there is no study like this, I'm a little shocked. With all the ABX tests that have been done before (on this board and other sites) why has no one used a lossless (ok ok "orginal") sample as reference? Maybe I'm missing something here... I'm by no means a statistical or testing expert.
