It seems that my last thread is not attracting enough.

Not many people reading.

So here's more attracting title :).

 

 

I put two files here, they are from the same song, the same part.

The source is the same.

 

They have different kind of distortion I added, each simulated some amps which I have measured.

 

Please vote your preference, see which is better sounding.

 

I have my own answer, but guy's taste may vary or confirm my theory.

 

Also, there is a "can't here the difference." answer, which I missed in my last poll thread  ^^||

 

 

The song was Vision from Jen Chapin's "reVisions: Songs of Stevie Wonder."

It would be easyer if you used a site like zippyshare to host the files so they can be streamed aswell.

Voted. 

 

Next test, WAV rather than FLAC, please.

Voted.

 

By the way, "here" instead of "hear"? You have got to be kidding me, that couldn't possibly have been a typo.

They sound the same to me, i'm not familar with the music though so could be I don't know what to listen for.

If there were no differences to you, then there're no differences  :)

Oops..... I'm sorry..... No spelling check for the title >_<.

Moreover, I disabled my chrome's built-in spelling check function, since it always keeps bothering me XD.

May I know why WAV rather than FLAC?

It can always be decoded back to WAV if we need it.

FLAC saves traffic usage......

 

It's lossless isn't it?

Just a personal preference for reference files - I bring them into my music editing suite, and it doesn't support flac playback.

I listened, I voted.  I'm anxiously awaiting more results.  It's been a while since my stats class, what sample size will we need for accurate results?

8 votes so far ^^||

Not bad compared to the one before.

Yet indeed this would need more results.

 

4 can't tell the difference @@.

Ha ha....

Well. I'll have a little illustration here:

 

One simulated SS amp. One simulated Tube amp.

This test is to see which was more preferable.

 

This should be done under no knowledge of which was which.

Without know what it's for, and just telling which was better would be best but no much interest coming in......

 

 

Hope this would help to get more sample.

A was EQed with more body in(I don't think I can band ID properly) 500 to 1k region somewhat? Gives that flute that oomph and vocals more body in one of the tracks. Anyways I think simulating the amps is of little use. A better simulation will be to play and record the track true real SS and tube amp. Because with tube amp you get a lot more factors which can't be simulated through EQ.

It seems to be mainly distortion, rather than EQ. If you subtract the signal of one file from the other, the difference sounds shifted up by one octave, which suggests 2nd harmonics. But it is a small difference, so it is not surprising many people voted that the files sound the same.

No, it's not EQ.

This was done by raising the tone of original track by an octave,which makes the original data into 2nd distortion.

Then lower the distortion date's dB by desires % of distortion I wish to achieve.

 

But I also put some changes in the distortion data. They have different patterns, and this pattern was acquired via measured cross frequency distortion rate of tube amp and SS amp.

 

So the difference of the two file are:

1. The distortion % is different. Tube's distortion is 10 times greater then SS amp, which was the usual result.

2. The distortion patterns are different across frequency. 

 

I didn't simulate 3nd and higher order distortion since I want to simplify the problem.

 

The current result is quite illustrating.

That does not simulate intermodulation distortion.
