Poor quality FLAC files

post #1 of 12
Thread Starter 

How is it that people are able to create poor quality FLAC files?

I thought the copy was made directly from the original media, so what is it that causes the file to sound rubbish?

Are people creating FLACs from MP3s they've made from CDs they copied off their mate, or what?

I've just obtained a FLAC version of The Wall, yet it's an absolutely horrible sounding file; it's muddy, extremely sibilant and just of generally harsh sound quality. Conversely, I have an MP3 version that's at a mere 153kbps yet it sounds much, much better. I just don't understand. Surely people on the internet don't lie about how they make their FLAC files...wink_face.gif

What mastering did you "obtain" in FLAC?

Er...pass. Just in case you've misunderstood me (though I don't think you have), I'm not sleighting FLAC files in general; the majority I possess are exactly what one would expect. It's just the odd one every now and then, y'know? This is the text from the log file:

Mastering meaning the original recording. What year is it from, what studio mastered it, etc.

 

That's the most important thing, not lossless or lossy. A poorly mastered recording will sound terrible no matter what, and a well mastered recording will sound great no matter what. Pink Floyd has been remastered tons of times, and many resulted in some bad recordings.

post #5 of 12

I agree, It's probably just the CD itself.

 

Lossy compression can't really introduce sibilance/harshness.

post #6 of 12

possibly pre-emphasis was put into that specific mastering. that logs CRCs don't match 12 remasters I've got on file.

I'm starting to suspect it was "remastered" with Windows Sound Recorder.

I think you answered your own question here.

post #10 of 12

A lot of people believe upconverting a MP3 into a lossless format restores the original format.

 

Luckily, like you quoted, there are cue and log files, and applications like Foobar allow for bit-comparisons between files.

Foobar, eh? I've not heard of that one before. I shall check it out in the morni...er...when I get up.

post #12 of 12

Probably a bad mastering ie. the original CD sounds bad.
