 Posted: Fri Nov 25, 2005 8:33 pm Post subject: Converting flac to mp3 |
 |
|
| Hello, I am trying to burn a load of flac files to CD. The problem is, that when I do that, there's only static on the CD. No music anywhere. I am burning it with Graveman. I tested if I could burn mp3s, and those turn out fine. So I was wondering how I could convert flac to mp3 (ofcourse I am open to others suggestions/solutions). I tried Sox, but it doesn't support flac. |

Please don't convert a lossless audio format to mp3. Convert flac or shn directly to wav and make your cd.

actually ogg does that, lame mp3 encoder @ 256+ bitrates actually maintain the higher frequencies, but in doing so use more bits in the high range making the low and mid range more starved of information. Ogg cuts off the top to maintain a high quality mid and low range.
tradeoffs. I use lame mp3 @ 320 abr, which theoretically yields higher than 320bitrates when the music needs it. I cannot tell the difference between it and my cd on high quality studio monitor speakers. |

Actually, lame only maintains higher frequencies when told to, I believe. And are you sure OGG/vorbis does that? I have to look into that.

Why not simply use Flac then. You're pretty close here to what flac achieves.
BTW, audio compression doesn't just chop of higher frequencies. It applies all sorts of psycho-acoustic tricks, like leaving out low-volume sounds when there are other louder sounds present.
As for the topic starter, just use the "flac" command to decode to wav and burn the waves on CD. |

This is a widespread myth. Many people seem to think that lossy compression works by simply discarding everything above or below a certain frequency, probably because how the compression really works is too complex for easy explanations.
This particular version of the myth seems to be mixing up MP3 with analog FM radio; FM has an effective frequency range that tops out at 15khz. However this isn't totally false: the grain of truth is that MP3 is less efficient at encoding frequencies above 16khz (there's no scalefactor for that scalefactor band), however this is compensated for through increased bitrate. This is assuming modern VBR encoding using LAME; if you're still using CBR, well, how does 1995 feel?  |

Actually that is what the abovementioned flac2mp3 script does.
AFAIK there is no lossy encoder that can read from .flac directly. (Heck it's hard enough to find apps that can *play* it directly...)

oggenc can encode directly from FLAC files. |

| But wasn't the idea to burn audio cd's? Then converting to wav is all that's needed. Intermediate files are useless and counterproductive. |

Gotta love the vorbis guys!

DOH! Of course!
My understanding was that he wanted to burn mp3 data CDs. I should really learn how tho read...
