WAV versus FLAC

For what its worth, I used EAC and ripped Williams SeaSymphony - TELARC: firstly in WAV format and then in FLAC format in two separate folders

On one hand I use low fidelity computer audio...so my results may be dubious

On other hand - After I listen to these a few times, I asked my wife to go beteen file#1 and file#2 and "click" and I was listening BLINDLY

Results: from 9 trials I indentified WAV and FLAC correctly 9 times and it was rather easy as each has its own unique sonic characteristic.

I cannot say which one is "better": WAV was warmer but softer and FLAC was crisper but not bright and with better PRAT factor. If this is true "forever" then probaply WAV is better for solos such as female voice and small ansembles and FLAC is better for symphonic music...

its not definite experiment but its was fun, please do not take it seriously.

I just had an idea, so bear with me.

First, people hear differences between file types, and some, like Simo, above hear it regularly enough to ID file types...or at least tell the difference.

However, this is testing the computer as much as the file type since each file type must be 'decoded' or whatever it's called.

A test?

Record a couple songs in FLAC, ALAC, WAV, whatever else. The brain trust tells me that FLAC and ALAC can reconstruct the original bitstream so they SHOULD sound alike, right? But NO!

I'd say to take the songs recorded in all those formats and change them all back to ANY format. I'll bet the differences will disappear. I think this means the difference is how the computer turns the file back into music, not the file itself?

Yes, those who measure files or compare file structures are measuring the wrong thing, IMO. I don't believe there is one single debate that wav and FLAC (or AIFF, etc) are identical files. However, aren't they processed differently (i.e the FLAC or AIFF decoder or codec is different than the wav one)? It's there that the debate should be focused on. Hell, we have debate over digital cables, and clearly the ones and zeroes are identical...but the path they take, the envelope they ride along, the dielectric they encounter...are different...and to some people (wayyyyy more than hear the diffs between wav and FLAC) there is a debate. I don't have any answers, but I am theorizing, I am simply stating that if two DNA-identical twins ride along different paths, they may look different at the end of the journey.....and yet still be measured as having identical DNA. Their DNA measurements are moot and not in question; their ride experiences are what's important.

Isn't that what I said?
My experiment would confirm it is the processing / conversion, not the file.

All the lossless files 'decode' to the same parent file, but HOW it happens is the difference.

That's what I've heard as the objection to USB as a feed to a DAC.

Alex, do you use your PC to decode FLAC into PCM stream and then feed into the DAC? I need to understand how you set up your system to understand your claim better.
