FLAC vs WAV


I have observed (heard and then tested so as to confirm) the following “condition” as it relates to the widely debated issue of FLAC quality. The purpose of this topic is to gather opinions as to whether or not your observations are similar too – and therefore support – my own.

It is widely understood and accepted that a FLAC file while “compressed” is “lossless” as compared to its corresponding WAV file. Let’s assume (i.e. not debate) this is completely true. What I am noticing is that when the FLAC file is “played” via any FLAC player it sounds different from the sound of the “same” (equivalent decompressed FLAC) WAV file when played back via the same player that was used to play the FLAC file. This is specifically noticeable (to me) in the low frequency spectrum. The WAV has considerably more “sonic energy” that manifests itself as appearing to be a bit louder, wider in frequency range and perhaps even dynamic range as compared to the FLAC equivalent.

I’m curious as to your findings when you compare a FLAC file played natively as compared to the WAV equivalent played via the same player (for example, play both the FLAC and WAV via VLC media player) or practical equivalent, such as if the FLAC was burned to CD and you are comparing the FLAC played via VLC and the CD played via a CD player.

I am further assuming that the WAV file is a more accurate representation of the audio than the FLAC. This is to say that should you agree with the aforementioned, it would be preferable to play the WAV file or decompress the FLAC file before using it.

As a relative newbie in digital world, I recently elected to rip my cd collection to have access to everything without going through hundreds of cd's. Using dB I started ripping at first in the flac default 5 compression. Playing back through my Magnum Dynalab MD 807T, I must admit that it sounded pretty good (at the time I did no A/B tests) After ripping many and coming to see that I did not need the extra compression due to using a external 4 drive enclosure for storing files, I deleted everything and re-ripped in flac uncompressed.

Having access to everything is a pleasure, but accessing through the computer seemed to be occasionally problematic. Errors popped up here and there (maybe once for every four hours of streaming). It presented itself as what I would describe as dropped bits, momentary silence etc. I then elected to move everything to a NAS and take the computer out of the loop for anything but operation control through JRiver. So I access the library through desktop/laptop or tablet and these momentary errors have evaporated.

Always one to read, experiment and verify, I am going to rip some cd's that are already in flac uncompressed format and sound exactly like the original material into WAV and playback using the same method above and see if there is any  difference that I can detect in my system. If not, I will consider myself lucky and continue using flac uncompressed and just get larger drives, if needed down the road.  

As a side note, I have been experimenting with changing playback parameters in the PS DirectStream, since it was recently added, to find optimum setting, there also there is going to be a learning curve but that's what a hobby is all about
