Rig in my signature... it might be my first and only rig, but I'd like to think that I'm doing something right here...

 

 

Immediately from the first two seconds, I thought it was apparent which one sounded better, but then I skipped to 22-30 seconds just to double-check. There is greater clarity in the drum hits in the lossless file. The instruments just seem to run together in this messy, noisy fashion in the 128 kbs MP3.

 

Now, if I weren't directly A/B'ing the two tracks, I am not so sure the lack of quality in the 128 kbs MP3 would be so obvious. But going from one to the other brings out the differences.

I agree. I was able to tell pretty quickly within the first few seconds on my DT770 Pro (80 Ohm)'s; the clarity, sharpness, and cleanness of the sound is so much better on the lossless file. And I also noticed how helpful it was having them side by side. Going from the lossless to the lossy on a part of the track, I "remembered" a lot of the details and was able to pick them out even in the lossy file; it was muddled but didn't seem so bad overall as I knew what I was "supposed" to hear. But going from the lossy to the lossless, well, that was a shock every single time.

I could hear a difference but I also believe this to be a bad quality recording.

A is a wall of noise at 9 seconds making me want to rip my headphones off.  B is slightly less wall of noise making me only cringe.

 

If this is the crap people use to blind test no wonder they do so poorly.  They're all deaf after 30 seconds.  I'd recommend the least transparent system available for mastering like this.

wow! i could tell almost instantly with the symbols. i took an other blind test that was 128 and 320 and i couldn't tell a difference. thanks for posting!

I always rip at 320cbr. I know it would make more sense to use V0, but 320 just "feels" more consistant to me, even although I can't hear any difference in an ABX blind test.

I'm sure there are plenty of other people who have said the exact same thing, but I knew that there would more than likely be lots of people that would post their answers in the thread, so I only read the original post and then downloaded the clips. 

Played them one after the other, and determined that B was lossless. 

It's interesting to ponder whether people were influenced by what others posted (placebo again) or what they heard.  Maybe next time someone does this they should start off by stating that you shouldn't post your answers in the thread and instead just answer the poll.

Is there a way to download the files without downloading Media Fire?

This is quite surprising at how many people can tell.

Wonder if it'll be the same if its 320kps.

A is distorted but B isn't good either.

Of course being able to hear artifacts depends on the individual, but it is generally known that 128 kbps mp3 is not transparent.

Actually, it's impossible to know, looking at the results, how many people could tell the difference, since anyone could read the numerous posts or view the results before voting.

 

The poll is a great idea. I just wish we could set it up properly so it would be a valid ABX test.

 

It's also quite annoying that the test is an ad for MediaFire. The internet has become so invasive and insidious that a person can't even f**t without downloading something. Not good...

You don't have to download anything other than the files. Just click the green download button.

Thanks

 

Call me paranoid. I get a bit wary when I see too much stuff on my computer screen.

Chrome + adblock and you pretty much only see the green DL button. Or you can hover your pointer on the button and make sure it isn't a link that takes you elsewhere
