Multiformat Listening Test @ 128 kbps - OPEN Options

[guruboolez]

(of course other than the case when ABX results are "against" ABC/HR ones  )

It can't happen with schnofler's ABC/HR. If a file is correctly ABXed, the bad slider is automatically frozen

[Sebastian Mares]

OK, I have at least 10 results for all samples now.

Happy New Year to everyone; three hours left in Germany.

Congratulations, it's 12:40 PM where I live.

2006 finally arrived here, too!

8 hours and 47 minutes to go...

Is that enough?

[Sebastian Mares]

No, but now people don't have to focus on specific samples for which I have less than 10 results.

Hi,

Is it possible to reset an ABX test after having pressed the "Finish" button? I pressed Finish after the 6th try but would like to test more.
Thanks.

PS: are ABX results included in the results of the listening test? How low the probability has to be to disable the bad slider?

All I can say is that ABX results are included in the logs. No idea about the other questions, though.

Anyways, how's testing going, guys? Slowly reaching the second deadline and I can't say I received a lot of new results.

The ABX "probability if guessing" that you must reach is set by the person making the test.

So if you don't remember, I'll guess it's the default <0.05

Ah, then yes, 0.05 is correct.

No, it's not possible. Otherwise you could just keep resetting and finishing the test until you get the desired result (pval<0.05) by chance.

Isn't such cheating already possible by "forgetting" to save the session, re-opening the test and trying again?

The likelyhood of being able to get a significant ABX on *all* samples with this method isn't very good

ok, started testing, some doubts:

1) can i use a pair of sony u$s 10 headphones? (i have no better)
2) as far as i can see, i rate all 5! (i must be deaf) should i try anyway?
3) when i press "ref" button, is it allways the unencoded sample?

thanks.

1) Probably yes if you still can spot artefacts, but it certainly won't make testing any easier for you
2) Same here, except for one sample, and that with Sennheiser HD600's
But you do recognise the low anchor, don't you? Otherwise you really should consider having your ears checked
3) Yes

[kwanbis]

But you do recognise the low anchor, don't you? Otherwise you really should consider having your ears checked 

cant even recognize the f*#$g low anchor

mmm ... so maybe for me 128kbps = CD quality is true!

I can ABXed low anchor in the almost all samples. But it's hard for anothers

so the question still remain, should i send an all 5 test result?

[Sebastian Mares]

Well, yes, why not? It IS a result showing that the encoders performed well.

Anyways, no offense, but you could have checked if you can spot differences before telling me to extend the test.

never thought it could be this dificult ... maybe i should had tried ... but it bet you didn't do it just for me

[Sebastian Mares]

Well, as I said in a previous post, I didn't receive a significant amount of new results which makes me feel a bit upset. It's not your fault, don't get me wrong.

Oh, by the way, thanks a lot to all of you who participated and helped me out during these weeks!

check sample #12 IMHO quite easy to detect low anchor ... but other encoders for me mission impossible and sample #1 annoying in original haven't checked others.. anyway can't recognise anything except low anchor...

i would check sample 12 right away. i suppose my cheap earphones could be the culprid also?

Well I just attempted to try to help with that, but I don't hear any sound when I try to play the a sample. In fact, I get no indication they're actually being played (is that normal)? I tried listen to just part of the sample with the same result. I believe I followed all the directions. When I play the WAVs with Windows Media Player I hear them. I upgrade to the lastest java (as I had an old version) but also didn't help. I also verified my directory structure is correct. Any ideas?
