what is the program you guys use to burn audio cd from wav files...
I cant find a program to do this, and yet the only one i have found doest seem to like the work mpg123 have done to rip from an mp3 to a wav...anyother good ripper by the way |

I use cdrecord, and I've never had a problem using it in conjunction with mpg123.
k3b has a nice ui for burning mp3 to cda, too. |

here's what cdrecord returns me after this command
| Code: | | cdrecord -v -dao -useinfo dev=0,0 *.wav |
:
| Code: | | cdrecord: Inappropriate audio coding in '1bc.wav'. |
while all i did with this mp3 was :
| Code: | | mpg123 -w 1bc.wav 1bc.mp3 |
any ideas what could have went wrong? |

Hmm...no clue. I usually use abcde to rip cds, but since it's giving me a headache I've switched to grip for now. But in either case to encode from wav to mp3 both programs use lame. You may want to give it a try as well.

Ah - I may have left out some pertinent information. You have to make sure the sampling rate is 44.1 kHz, which won't necessarily be true for all mp3s. Try writing to stdout with mpg123 and piping the output to sox to correct for this. Here's the command I use to convert mp3 to wav:
| Code: | | mpg123 -s blah.mp3 | sox -t raw -r 44100 -s -w -c 2 - blah.wav |
Perhaps that will help. |

well, it did half the work,,,
the .wav that resulted of the operation is playing like 1.5times faster than it should play...
any idea why...
ah and one more thing, how do i perform the operation from mp3 to wav for several files, but in one command...cause for a 20 songs cd, it can be painfull...
i cant seem to figure out how to tell sox to make the wav the same name as the mp3... |

Strange - I hadn't noticed the reply before. Sorry about that.
I'm not sure why it would play 1.5 times fast. Is it playing too fast on the cd, or are you just playing the wav with something else? What are you using to play it back?
I wrapped this up in a script to burn cds. Basically, I pass the script a file containing a playlist of tracks that I want to burn, and it converts them to wav, normalizes the volumes and burns them to a cd. It's a bit kludgy, but I can post it tonight when I get home if you'd like. |

I don't have a whole lot of time to explain it, but basically just save this script, and call it like this
| Code: | | your_script_name playlist_file |
The playlist is just a text file containing the absolute paths of the files you want to burn, one file per line.
I hope this helps a little. Let me know if you have any trouble. I didn't really intend it for general consumption, so it may have some quirks. |

That script produces wav files that play extremely fast. Any idea why?
For me, it compressed a 60min mp3 file to a 7min wav file. |

If the in and out rates are different (mp3 isn't 44.1), then try adding resample after the out filename.

| you could try something like this: mpg321 -q -r 44100 --stereo -w, maybe that will do the trick. |
