I just think everyone's making poor excuses...

Well, I don't know how you do it, but when I encode (tried more than one codec) I hear an audible difference no matter what song I convert and compare. I tried LAME and I think something called FSH which GoldWave uses.
Purely as a diagnostic, have you tried encoding a sample of perfect silence and listening for artifacts? I really don't know much about mp3 encoding, but most lossy compression schemes that I've encountered in the past have been adaptive. I could imagine artifacts being more common with sounds that uses the full dynamic range but if you were to use a wave file which has been mathematically constructed to contain silence, then any errors due to encoders, incorrect usage, faulty audio hardware etc. would be evident.
It seems suspicious that you have problems when you encode your own music which you're not hearing from the reference samples that Koyla's provided.

Nah, no tricks involved.
Fair enough. I guess I'm just a little paranoid...

N 1 sounds less accurate to the point that is off tone, it has no bass and is more nasal.
N 2 sounds more filled, with more bass and with the right tone, it was however not very good at the end of the sample, and some what strident overall.

And yes we can hear differences on music we know before hand.
When encoded they would sound different that the original.
Most differences occur when heavy instrumentally music is compressed.
I.E. The perfect drug Nine Inch Nails original CD (German import) versus mp3 320kbps.

I reckon the second file is the higher quality.
And why is this in the shock forums?

I agree, but let's not bias things until people have voted. [/spoiler]

It's here because of the thread meantioned in the first post.

It amuses how many times I've seen the words "guess" and "I think" in this thread, while a day or two ago ppl were pretty f'ing certain about audio quality :rolleyes:
After all... you have a 50% chance to get it right even if you pick randomly. Kolya should have uploaded at least 7 or ten samples to make this thing reliable at all.
Martin Karne on 17/5/2007 at 23:55
Not all, when you get to know the original CD/DVD audio music you can tell easily if it sounds different.
However we have no access to an original file to compare the samples and if we did we didn't had time to get acquainted with it.
Anyway audio is a subjective experience, that's why there is people making loads of money selling costly speaker spikes and people that buys them.

You are supposed to vote the option you think sounds better. 2 options or 7 - 10 ain't gonna change anything, except 7 - 10 options would be way too much.

Umm, no, you're supposed to vote which one you think is worse.
