Hi list and thanks Rob for your answer,
A few complementary questions, again maybe a bit OT:
I do not really need wav format (by the way, is wav in some way a ms invention?). What I'm trying to do is to decode a lot of mp3s to a format usable for listening with a non-mp3-capable cd player, i.e in my car, and then burn them to CDs with k3b. At the first stage (before burning) I would like to save the mp3s as individual output files in another directory than the mp3s.
1. Is .cdr a format for my purposes? 2. Shell scripts are a bit beyond my capacity for the moment (but I'm learning fast). What do you mean with "The above is for Bourne-derived shells; hopefully yours is not of Csh variety."?
What about this? If i navigate to the directory where the mp3s are and then:
for file .mp3; do madplay -o -v $file.cdr $file; done
Where in this little script should I put the target directory name (called "cdr)? What does "done" mean? Close?
TIA /jrx, Stockholm

Hi, maybe OT. I have tried to decode an old mp3 with various settings to wav with mad, and the decoding seems to work fine.
But when I try to burn the wav with k3b, k3b says "wrong format". madplay -v -i -m --output=wave gives "Layer III, 64 kbps, 22050 Hz, single channel, no CRC, 7095 frames decoded, -7.4 dB peak amplitude, 0 clipped samples"
Does anybody have any suggestions about what options I should choose when decoding. I would like to have it in wav.
Or maybe I should look in my k3b settings for this particular file..?
Best regards /jrx

Hi list,
I would like to decode a whole directory in a bunch. Probably I have to use some kind of ordinary *nix command (I'm from the other side), but I can't figure it out, and I can't find any description of this presumably easy matter in man madplay
Thanks in advance.

If you're trying to burn an audio CD, try:
madplay -o cdda:track.cdr
The result is a raw CD audio track ready to be burned.
If you really must have a WAV file, you'll have to specify all the parameters yourself:
madplay -o foo.wav --stereo --bit-depth=16 --sample-rate=44100

Yes, as I understand it the WAV file format (RIFF/WAVE) is a Microsoft bastardization of the IFF standard originally developed by Electronic Arts (EA IFF 1985).
What I'm trying to do is to decode a lot of mp3s to a format usable for listening with a non-mp3-capable cd player, i.e in my car, and then burn them to CDs with k3b. At the first stage (before burning) I would like to save the mp3s as individual output files in another directory than the mp3s.
- Is .cdr a format for my purposes?
Sure; most CD burning programs ought to be able to use the raw audio data written by madplay to such a file.
- Shell scripts are a bit beyond my capacity for the moment (but I'm

This is definitely off-topic, but FYI --
There are two great classes of UNIX shells: the Bourne shell and its derivatives (e.g. ksh, bash, zsh), and the C shell and its derivatives (e.g. tcsh). The former class is generally more powerful; the latter suffers inherent weaknesses but is unfortunately a common shell for interactive use.
To find out which you have, you can 'echo $SHELL'. If you get back something that ends with csh, you'll either have to change your scripting style or change your shell. (Sorry, I can't help you with csh scripting.)
What about this? If i navigate to the directory where the mp3s are and then:
for file .mp3; do madplay -o -v $file.cdr $file; done
Where in this little script should I put the target directory name (called "cdr)? What does "done" mean? Close?
Try something like this:
for file in *.mp3; do madplay -v -o cdr/$file.cdr $file; done
"done" marks the end of the "for ... do" loop.
