has anybody else noticed this about flac audio?


o.k are you ready for some truth friends ? flac has compression levels from 0 to 8 with the official flac default level being 5. now flac is lossless compression so there should be no sound loss from the original source no matter what compression level you use however if you encode the same song using every different flac compression level even though they will all be lossless there absolutely is a difference in the overall sound including tone and sound stage from level to level and doing your own test will only prove me right. now here’s where it gets strange? vintage vinyl has stereo + stereo depth perception (3d sound stage).digital audio has stereo + mono depth perception (2d sound stage) and this includes all new remastered vinyl cut from the digital master. this is why digital audio does not sound like vintage vinyl along with brick wall compression.i find it odd that the only flac compression level not recommended as a default no matter what software you use is flac compression level 4 ? it just so happens that re-encoding digital audio to flac with compression level 4 converts digital mono depth perception back into digital stereo depth perception (3d sound stage) just like vintage vinyl! and i don’t think this is by mistake friends ? do your own test and get ready to have your mind blown. here is an audio sample: level 5 http://pc.cd/pCcrtalK level 4 http://pc.cd/iVWrtalK

Just a comment to point out that there is a BIG difference between comparing a LP against the commercial CD or hi-rez release versus comparing the LP against a digital copy of the LP made using your own equipment.

Anyone who has ever looked into what it takes to make a LP will understand why vinyl playback can be so unique. First, the RIAA curve used when cutting the LP has a 40 dB swing from bass to treble. This curve must be matched exactly on an inverse mirror image basis for playback. Second, phono cartridges are a mechanical device that have just as much variability as speakers. When was the last time anyone thought two different brands of speakers sounded identical? Add to that the unique technical constraints involved in cutting an LP and the trade-offs involved (time on each side versus amplitude, groove variability, etc.) and it is no wonder that LPs offer such fertile ground for searching out a unique sound.

Digital recording certainly has its own unique considerations, but they are on a completely different plane. Given that, it is no surprise that the LP release almost never sounds the same as the commercial CD or digital download.

However, when I make my own digital copy of an LP, using my own equipment, I find the digital version is very difficult to distinguish from the vinyl. The digital version has done an excellent job of capturing the quirks and traits of the LP, so much so that I cannot reliably tell the difference between the two versions if I have been careful in my transfer (no clipping, etc.) As noted earlier, I spent about ten years transferring over 1,000 LPs to digital and was so consistenly pleased with the results that I gave away most of that collection several years ago. I still don't miss having the vinyl. Nowadays, my turntable sits on a top shelf, unused, except for the rare occasion when I bring it out to transfer a LP for a friend or something unique that I've stumbled across.

mlsstl, can you describe your process and the equipment you are using? What resolution, sampling rates?
My conversion project started in the early 2000s and was finished eight or nine years ago. My equipment wasn't all that fancy - a Dual turntable with an Ortofon cartridge, and a Conrad Johnson preamp that fed a Dell PC with an aftermarket sound card (Creative Tech, as I recall.) Software used was Adobe Audition with recordings saved to flac file format at CD rates (16/44.1KHz.) 

Just a side note. I do not consider myself an "audiophile" -- the term has acquired way too much pretense over the years for me. I am just a music lover who also enjoys quality sound. I'm only describing what works for me. As they say, take what you want and leave the rest. 


Hi there,

I have a question about this flac format since I haven’t used it yet. Is there a significant difference between Flac and Alac (apple lossless...)? If you think I owe to try it, which one would you recommend as a flac ripper? My tuner/media player has a flac capability just checked it. 

guitarsam here and i am not an audiophile and i realize that it makes no sense that flac with compression level 4 should sound any different than any other level.
i can accept that i’m fooling myself and my ears maybe fooling me.

she by gram parsons ripped from cd with jriver media center 23 to flac (0) and flac (4)
what i believe i hear is a more open soundstage with more stereoness to the music on flac (4)
