Thanks Mooly and Dirk for your impressions. I'll have to look at my code 'cause I can't remember which is which!
I'll wait a few days before I disclose the identities.

Well, given my poor hearing, and the fact that I used MS Media Player driving a Little Dot DAC_1 via USB 3.0 and using Sennheiser HD598 headphones via a unity gain headphone amp, I'm surprised I could hear much difference at all. But version A was clearly better.
Thanks.
I want to provide lossless files (FLAC) for the full experience, but will cut them down to about 20 secs long for file size issues. Would a 20 second clip be enough for you guys?

I've nothing that plays FLAC files tbh. For myself I think the 320kbs MP3 played as I did would be better than FLAC via my laptop.

OK, thanks. The differences should be big enough to show up in a good MP3 anyway. We are talking about running a signal thru fruits, veggies and mud. 😉
A new wonder every day when you think you have seen everything. I suppose men in Asia will want versions filled with snake urine.
All I have to say iz that the Tennessee version would be running through BS - which means that I'm going out the same door that I just came in through...... 😀😀😀
We can always count on you, Thomas! 😀
Hey, the experiment is easy to do. Why not try some B.S.? or is there too much on the audio forums already?

Definitely keep it blind. When all is done, it might be fun to put up ten files, randomized between copper and potato.
This is better than the canonical coat-hanger!

I was thinking about your coat hanger trick, SY. This is more extreme.
Next project is to make a potentiometer volume control out of mud. Should be easy.

Listening through Sony MDR-1R on a laptop.
If you held a gun to my head I'd say A and D were a little dull, but the difference is so minor it could be psychological.
I wouldn't be at all surprised if you said they were all the same file and you were waiting for someone to make a fool of themselves! (let's wait for all the people claiming to hear the obvious difference to appear when the coding is unveiled!)

I should add: this was an analogue, not digital signal?
'cos we all know what a difference quality digital cables make

Thanks nannoo,
Yes, this was an analog signal, line level. About 1V or less RMS.
I could trick everyone and use the same file, but I didn't, that would be cruel. 🙂
No, they really are what they claim to be, the original, the loop thru a wire, the loop thru mud and the loop thru a potato and a banana. I did not record the orange.
A 440Hz test tone was run first to set record levels as close as possible, then a slight digital volume control was done in post so that they all match in level by better than 0.2dB
Also, in the mud and the banana recordings, the right channel seemed to pick up more noise than the left - not sure why. The noise is down >50dB, but I went ahead and pulled it out with a digital filter, just so that someone clever couldn't tell.
Therefore all files but the original have had a little bit of digital processing done to them. Slight, but still processed.

Nice set of files, Pano ... pretty obvious, C is the original - on a quick listen with Audacity, on the PC speakers. All the others are degraded to some degree, interesting how much the straight DA/AD loop damaged the sound so much ...
Will have a go later on guessing the other 'fits' ...

How about a goat? LOL.
Actually my first test was..... me. From left hand to right. It worked OK but with a marked bass roll-off. I didn't post that one, as it's a bit too, you know, personal. 😉
I think I can make a volume control out of sausage. Will try it later this week.
Very rough guess on the rest - my wife got a headache hearing the first round, so 2nd round was at very, very low volume!
A - copper
B - mud
D - food

Fas, your posts make me looool!
>>so the straight digital conversion does "a lot" of damage to the sound
>>but you can't identify it instantaneously against the mud/potato?
I'd bet C is the conversion loop, B is the original.
