I have to say that even using headphones (Senn HD555) for some samples I couldn't tell the difference from the original. For others the differences were very subtle.
Either codecs improved a lot or I am losing my hearing (or both!!)

High anchor for some samples is indistinguishable  for me. As it's 48 kbit/s  test I expect that the result is still valid  if only high anchor isn't spotted.

The result is valid if you don't spot anything :B

Why should only people that can hear artifacts be allowed to participate?

Yep. It's real life test.
In extremal case listener can be totally deaf or has serious  problem with hearing. But it's not common in this forum.

I'm getting a weird hang when adjusting the playback range in the ABX section (only happens occassionally, but it's catastrophic when it does happen)

Bummer, maybe schnofler can help.

I had it hang once or twice as well. Also, it seemed that whenever I saved my session, I was unable to change the rating sliders without first reloading the session, but everything else still works.

This is soo cool.  If I have time I'm going to complete all of the samples.

I managed to decompress files on Linux using

Code: [Select]
wine cmd /c Sample05.bat
(instead of wine wcmd as it states in the docs)

Using Wine 0.9.22 on Ubuntu

I sent you my 20 test results also now, just wanted to make sure you got them. Fun test!

Thanks to all involved!  I'm not going to go into any extensive ABX testing...if it's imperceptible, then I'm voting 5.  This is mainly due to my left ear hyperacusis, which tends to interfere with involved listening tests such as these.  I hope these will be acceptable results!

I hope this doesn't skew the results too much but many times I think I have a good idea which sample is AAC+ based on that SBR graininess. :X

The samples are often pretty easy to pick out (though there's one or two contenders that do a good job!), so don't worry too much.

To be honest, I tested some samples myself just for fun (did not save the results of course) and for the majority of the samples, I was only able to pick out 3 codecs.

Oh, didn't know about that one. I only edited the listening tests wiki page myself.

Just out of curiosity, how many samples so far? Is the participation on this test being significant?

Multiformat Listening Test @ 48 kbps - OPEN
Reply #69
I have something around 10 results per sample making a total of 200 results so far. Keep 'em coming!

Good to hear that you're getting plenty of testers.

OK, I decrypted all result files, sorted them automatically using ABC/HR and the wonderful ReNamer with its regexp replacing method, eliminated all invalid results (ranked reference without ABX test) and then counted:

Sample01: 13
Sample02: 15
Sample03: 13
Sample04: 13
Sample05: 13
Sample06: 10
Sample07: 16
Sample08: 12
Sample09: 16
Sample10: 12
Sample11: 13
Sample12: 12
Sample13: 13
Sample14: 14
Sample15: 14
Sample16: 14
Sample17: 12
Sample18: 15
Sample19: 15
Sample20: 15

Three days left for testing and it looks like I don't have to extend the test. I would like to ask people to start sending results soon if they haven't already.

".. without ABX test".

Isn't enough just to move the sliders up and down and then save via "Save Test Results.." ?

It is as long as there are no ranked references.
