I see that frog is busy trolling again (that's his personal problem or should be), and I will reiterate that his contention that "it cannot be heard" is both unprovable and illogical. I provided names of 2 serious and very accomplished engineers who have contributed to the field, and frog (who is not accomplished) merely sputters insults.
Well here's someone who seems to be able to prove it:
http://www.computeraudiophile.com/blogs/mitchco/flac-vs-wav-vs-mp3-vs-m4a-experiment-94/
http://www.computeraudiophile.com/blogs/mitchco/flac-vs-wav-part-2-final-results-155/
and I would contest your assertion that it is illogical that two identical digital files should sound the same, provided that the computer is up to the job of unpacking the flac file - which is of course lossless in the same way that a zip files is lossless. It seems to me to be plainly obvious that they should sound the same because they are the same! Incidentally, playing a flac file on my laptop through a USB dac increased the processor useage from 0% to... 0%, jumping to a whopping 1% every 10 seconds or so. Memory usage increased by a barely perceptible 20 meg (out of 16 gig). Playing a wav file was exactly the same. Repeating the experiment using the laptops soundcard and internal speakers gave the same result. Seems that playing wavs or flacs on a modern well specified computer is a trivial task.
What I could hear very clearly was the difference in sound quality between my HD650's and the laptop speakers proving to me that although I would never claim to be golden eared, unlike the sound engineer I'm currently working with, I could justifiably claim to be slightly tarnished silver eared...
Could it be that the engineers you refer to above have any kind of ulterior motive? Would they be well past their peak in terms of working life and doing a bit of self publicity or would they perhaps be the music industries equivalent of 'creationists'? Or all of the above?
Just tell us that you're joking, yes? A FLAC and its unpacked WAV equivalent aren't the same when they are in those different formats. When the FLAC is unpacked to WAV format, then the WAV and WAV are the same, if they started out the same. There is no guarantee absolutely that I'm aware of that a music player will perfectly unpack a FLAC in real time while playing it, although it may do a perfectly fine job of it.
There are a few people, and Diament as well as the other guy may be two of those, who have found that really identical files can sound slightly different when affected by external circumstances that they're not aware of OR in control of. I don't have a problem with *that* claim, however, 2 files that checksum identically are in fact identical for purposes of archiving, backing up, mailing, normal playing, i.e. all forseeable uses. But, computers are complex little beasts, and two files that are identical for all normal digital purposes (i.e. really and truly identical) can exist in certain different states, for example one file may chkdsk as being split up into 100 non-contiguous pieces on a FAT table, while an identical copy may be fully contiguous. Now before you go waving your arms around virtually speaking, just admit that I'm right, that these 2 files could exist in these states and that there's some possibility (however small) that it could affect their performance. If you refuse to accept that difference, never mind any hidden assumptions about what else I might be implying (nothing that I don't state actually), then you don't know digital computers and storage.
