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.

In case you don't browse the forum using the sections, you can find some ABX tests in the "listening test" forum : http://www.hydrogenaudio.org/forums/index.php?showforum=40

Here are some old ABX tests at high bitrate :

I've been here since september 2001, and never saw a study about lossy compression at high bitrate, exept Guruboolez' one, below in this forum section.

128 kbps tests run by Roberto Amorim and Sebastan Mares are the hardest that a large number of people can undergo. For higher bitrates, only some poeple can perform some ABX tests with some samples.

I've heard many times about a professionnal german study that tested MP3 at 256 kbps, before 2001, and that concluded that it was transparent to the listeners, but it seems that the paper is not on the Internet anymore. I've read that they listened with Senheiser Orpheus headphones.
However, many problem samples are known, see the above links.

The alt-presets for Lame were developed around 2001. As far as I remember, no ABX tests were published during the development. I think that the dm-presets have undergo some ABX tests, but it was in a forum that has now been taken offline (r3mix.net)
