How to vote in this new threadCLICK HERE

I am opening a new thread where you can vote for your sound preferences. I have prepared 2 sound files in a very high quality, 48kHz/24bit, uncompressed, with level matched within 0.01 dB. The poll will be added soon. Please do not post any comments on sound quality and preferences here, just vote which sound file you prefer (or no difference heard), after the poll is available. Any technical details will be posted no sooner than the poll is closed. I can only disclose that the difference in HW used is not small.

Edit: for the reason that the poll is over, the links have been deleted.

How to vote.

To vote please click my user name (Mooly) and send me a pm indicating your choice.

The poll is hidden so that no one is influenced by seeing how others are voting.

There are three choices.

Blue
Green
I can not decide

does download have to be so complicated
can i host the files to my server to make it easier ?

Kind regards
Sakis

Hi Sakis,

yes, please feel free to upload the files to your server. Sorry for problems, I upload the files very rarely.

Probably only "slow" option works for free download from filefactory.

***link now removed as poll and test is over***

I also cut the files so they start at the same time.

Thank you, but please do not modify bit depths or sample amplitude.

I haven't changed anything else but the start of the files.

For people who do not know about foobar ABX, this video is very handy.

I think we should try and keep the test simple and just base it on listening tests 🙂

If there are no objections from anyone that has so far posted then I can tidy this thread up.

As the FileFactory download is rather slow, I´ve placed the (unaltered) files
on my server:

That IS a listening test. Before you can decide preference, first step is to find out if you can hear any difference.

So it's no longer double blind... Why is it so g**d**mn difficult to do it right for a change??
Another missed change - people will no doubt argue that some will want to hear a difference, hence vote biased...

Yep, I see where your coming from on that 🙂

For me, if I can't hear any difference then I will not vote.

But where 's that qualification process? I just see Blue and Green.

There's less psychological entertainment aspect here as compared to the previous poll. Why would anyone get excited and do the test and send the vote???

Some information may be needed, such as "This will be fun!! We are comparing 4558 with 4560!!!"

Why not? "No difference" is an absolutely valid choice, if that's what you get.

 

[PMA]

Jan, if you stop then the people will not be biased. If I wanted to fool someone then I would post two same files. That's not my intent. Yes, I want A-B test.

Definitely!
