Can you participate to a listening test?


Recommended Posts

I would like to kindly ask you to take part to a simple listening test which we have already done in Italy and I would like to extend to you.

 

http://uploading.com/files/ab15emea/test.rar/

 

At the above address there are 2 files - A and B - 2 minutes each, free samples at 24/96khz.

 

Please listen to them carefully and report here if you hear any difference between them and, eventually, your preference.

 

Thank you

Quick listen three times each on a secondary system I have, I don't have a preference. Will try tomorrow on my main speakers and see what I think.

 

And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality.

You might add a bit more info as to why you're doing this, what it's about, that sort of thing. Even I don't like to go into anything completely blind--no double blind test pun intended, and I'll try just about anything.

 

Anyway, it might help you get a few more responses, or maybe just criticism. Who knows--actually I do, criticism.

 

However, the odds are that no matter what you do, you won't get many takers, particularly where it comes to folks that can hear everything.

Intentionally I would like not to give to much info on the files.

However, it all started on the possibility to discriminate differences in listening tests.

To be honest the test I suggested cannot be scientifically rigorous. It is a field test and the more people take part, also non-audiophile, the better.

Obviously, at the end the "secret" will be revealed...well, it is not much of a secret but at least it's fun :-)

I'm surprised that I do not get much response here, after getting 19 pages of responses and measurements in Italy :-)

 

There is no trick in this test. Please, just play randomly the two files...and make your comments.

 

In the end, I will obviously provide statistical details and abundant measuremnts (even beyond a simple software matching or NTD).

 

Thanks for your support

Hey there ...

 

I'm always in for these kind of things, despite I hate A-B stuff. Anyway, I did it;

 

Listened to both only once upsampled to 768 and to my idea both sound good. I would have said very good if it weren't so that I thought hearing distortion of the snare drums through the basses. This looked more the case in A than in B.

 

Next I played the first 10-15 seconds of both another time, and I did the same while at their native rate (96).

In this occasion I thought I heard a differentation in the zoom-zoom-zoom-zoom of the basses on B where the even measure is somewhat higher pitched than the odd ones (so, just a slight movement of the finger on the neck). I didn't notice this on much on A, also not when I played it for the second 10-15 second occasion.

 

If I *had* to chose one I'd chose B for being better. If money were involved I'd rather say they are equal.

So, worth nothing much.

 

Btw, I never looked at your Italian website or anywhere, and maybe it would have been better if we don't post about it openly ? well, I guess at least I just did. :-)

 

Regards,

Peter

I took a listen and at first thought A sounded a bit more "raw" and a bit more ragged at the top. B overall sounds more "solid" and perhaps a bit rolled-off in treble. For general listening, I preferred B, though it almost felt like something were missing in comparison with A.

 

When I did a real ABX on them, though, I couldn't reliably detect a difference :/ so can't truly say I have a preference.

 

So there you have it - will be interested when you post the results and the "secret" ;)

Please specify your selection-preference.

If you cannot hear/perceive any difference between the 2 files, they are "I"(identical), otherwise they are "nI" (non-identical) and eventually A or B for personal preference (if you feel like).

 

@esldude

can I put you down for "I"?

 

@Peterst

you cannot have it both ways.

Can I put you down for nI-B ?

 

@jhwalker

in your view are they different or not?

Can I put you down for nI-B ?

 

Thanks

No, haven't listened on my good rig yet. If you can give this evening, I will see what I think. If you can't wait, then yes, so far I am an "I".

No you can't. Read jhwalker's response; I almost said the same. And if I didn't say that, I do now. :-)

 

Edit : No, I didn't say that, but I sure thought that something was not right in B either. I forgot why.

But it's ok with nI-B.

Okay, got a chance to listen on better equipment. There still isn't much between them. I too would choose B. The A file seems to have a hint of low level noise or slight fogginess around things at lower levels. But it is quite minor.

 

Something about it sounds like it was from an analog source. Maybe tape or even an LP with some post processing for noise, pops and such.

 

ni-B is my choice in any case.

Are there more free downloads? In the USA free is the preferred way to download .

Hey, I didn't think about this. It (analogue source) would explain why I "judge" it as good (which I normally do not from Hires). Especially the noise filter could explain the distortion I perceived from track A (although I didn't perceive any typicle noise reduction anomalies).

Much as I hate to make a decision given I was unable to ABX the two files on subsequent hearings :/ I have to say my first listen told me B was "better".

 

I still think A may be the more accurate reproduction of the original performance, but B sounded more pleasing to me the first time I played the files.

Tried on my notebook speakers (obviously nothing to hear), my home setup (DacMagic, Genelec monitors, at different volume levels, no differences), and on my work setup (Focusrite Scarlett, headphones, nothing here, too). Both fast switching and listening the full two minutes.

 

So count me as definitely considering them to sound equal.

 

After listening I also took a look at the files (even wrote some quick analysis script counting and quantifying the differences). I won't share my insights prematurely here, though ;)

 

Cheers,

Peter

I find listening tests interesting and challenging, however I am bowing out of this one for technical reasons. After spending 30 minutes downloading, virus scanning and downloading the software to try to open the files, I just gave up. Simpler access to the files would have kept me playing along.

Simpler than a RAR archive of two WAV files??? Not sure I get you ...

Not sure why. But I choose nI-B, on my Benchmark DAC1 and Sennheiser HD650.

 

I do get what Brain A is saying though. It was a hassle to try this out.

First, the download site has so many places to click on, it's confusing how to download the file for free.

Second, the download speed is on the slower end. After all, we are downloading 24/96 WAV.

Third, it's in RAR so I had to download and install Razilla Free UnRAR before I can unzip the files.

 

Finally, 99% of my music collection is classical music and I'm not a big fan of the performance here. That makes listening back and forth painful.

 

But it's nice to try these things out and learn about my own subjective biases. I'm sure the results will be interesting.

I tried to download the files, did that and couldn't open them. Also, many people are reluctant to open files because of fear of viruses. That may be part of the reason you are not getting much response.

Best regards,

I don't get it. So, this *is* classical I'd say, and it even sounds very nice (to me).

But maybe you ended up with some Black Sabbath ?

Hoping I don't breach any laws:

They are 100% clean WAV files, no malicious code, nothing to unpack ;)
