It isn't. And FLAC allows higher resolution and bandwidth recordings- whether or not that's audibly "better" is as-yet not demonstrated, but the objective measurements are. If FLAC recordings sound bad, you may have a computer or soundcard problem that should be fixed.

What are you using to play each of those formats? Are the FLAS files originating from a CD or they are from unknown sources?

FLAC is Free Lossless Audio Codec and is an encoding method that preserves the original data while saving space with compression. (hit Wikipedia for more info) If you were to encode a CD with FLAC to create a .flac file, in theory it should be absolutely identical to the original CD on playback. In practice it is likely that your computer will do some processing on the digital data as it passed from disk to output, but that has nothing to do with FLAC.

I think the more interesting question is something like "Does high resolution digital source sound better than the 44.1kHz CD standard?" And I'm sure that has been beaten to death in other threads.

In therory you could make a flac from wav and encode the flac back to wav, than compare both files, the original and decode/encode with a binary compare program, they should be identical.

..i test with my cd convert to flac..and listening with same system..
different is i play CD audi using ps1 ..then play flac with PC using AOpen AX4B-533 Tube Motherboard.

what good in sound quality FLAC level 5 or Level 8 ....(is size different ..who is have larger file?)..

I looled because I didn't know FLAC had "levels" - these links should help:
What Encoding Level is Best for FLAC? - iAudiophile.net Forums
FLAC - documentation

The levels just determine how aggressively flac tries to compress the files, and the resulting difference in file size is tiny if at all, but the time to do it at the higher values is significantly longer with more cpu power required in compression and probably in playback. (I haven't confirmed this, and with quad cores running at 3GHz I probably would not notice in playback were this true) Level 6 compression should be fine for normal use.

i am my self use level 5/6 in my other pc to compress (i7 +8g ram)

but back to : flac level5 vs level 8 what is good?:confused:

some say that is same sound quality ..then what use they make level5/6/7/8 ?:headbash:
or because our ear cannot tell /hear what is different flac5/8..
