Ripping to FLAC uncompressed

FLAC is by definitiona a lossless compression, but it does also support a completely uncompressed format, the protocol support it but the rippers seems to not.....

I am using Exact Audio Copy and even running the flac.exe conversion utility with minimum compression I end up with about 30% to 40% compression. Anyone out there that have any clues or ideas how to make this work?

just rip to wav/pcm files and you'd get your lossless and uncompressed :)
You'd want to use FLAC with compression since it 0 effects on quality. GIGO.

Wav has no metadata and flac decompression takes cpu cycles, hence flac with zero compression

First, I don't know which cpu you're talking about, but I'm running fully blown Plex server on what basically is atom cpu (ie Celeron J3455). How possibly high cpu usage is with flac playback could be?
Second, WAV file absolutely could include metadata

It’s been claimed it makes a difference, so I want to test ....

EAC does not have provisioning to provide metadata on wav .....

Got a source for this claim about cpu processing of a flac is meaningful?

I read in the paper edition some years ago :)
if I remember correctly he even did measurements to prove that there is a difference between compressed and uncompressed flac out of a hi-end dac, even from a computer that is not cpu constrained, playing the files.

I am not able to find this on the Internet, will look for it !!!!

At least I'd like to see if there is any difference, there are many things that shouldn't make a difference that actually do, and it doesn't cost money to try out....

Anyway, today there is zero reason to do compression, disk space is almost for free

I've heard of such claims from golden ears that they can hear differences flac vs wav, and haven't seen any measurements to show differences, that could be interesting. Just as storage is cheap, so is processing....it's probably not meaningful at a guess to process flac; I certainly can't tell the difference. I'll still save some space for my audio files when they'res no downside, and the meta data is one reason I didn't use WAV.

I remember I was able to play Flac files back in 2011 on my Galaxy S2 phone. While I could see the difference in CPU usage between decoding FLAC or just paying uncompressed WAV, for the life of me I cannot see any scenario where on modern even most modest computing device it would make any tangible difference.
Even on $5 Rasberry Pi Zero sbc.

I think you should head straight to here and clean this nonsense out of your head right away:

Disagree. The difference of 70% reduction is not marginal.

One guy’s personal non-scientific approach

I don’t buy the argumentation, some few identical measurements does not prove there is no difference... some things are different even though you probably can’t prove it with measutements.

The thing that this guy can’t hear a diffrence on his rig dores not mean there is no difference in other setup’s

Connecting my squeezebox to Benchmark DAC1 via optical is superior to spdif, while connecting an old Denon DCD-2560 CD player, spdif is superior to optical. I assume this would measure identical, but is to me audibly clearly different.

Audibly different is meaningless unless you know what the difference is. Is it simply a bit louder, is that the difference?

It's really easy to prove (or disprove) it using null-test. Just capture both wav and flac using same recording source. invert the polarity of one of them and play the result. If you hear anything but pure silence then you're correct.
Otherwise, your points are moot.

I don't know what the difference is, never tried... louder or not louder has no meaning but if music is more natural or not, it makes a difference. If I understand correctly, the claim is that there may be timing differences that is essentially being materialzed as audible jitter artifacts.

At this point, Haralda is simply trolling us. Intentionally or not.
Did the shop owner use pure silver cables in the demo? How about cable risers and resonance reducing stones?
So, what we have either your sound memory is not as good as you think, or you're not nearly unbiased as you think on expecting different result even if all was done is pure placebo.
this is on another thread now.....

It's your loss..... that you don't want the best out of your system.....

You send me the gizmos/sprays from the hifi magic man and I'll be glad to independently test them. I'm not buying such parlor tricks, tho if you also use vinyl there's a demagnetizer for that, too! The system is what it is....your state of mind during a shopping trip, who knows.
