I have just tried this to change my wma to an mp3:

anybody else know whats happening? obviously, they won't play with any player, although the name does thange to an mp3.

this part has to be wrong... "audiodump.wav -o $i" that means that audiodump is the input, and $i is the output, clearly wrong... change it to "-o audiodump.wav $i"

made the necessary changes you suggest - got the following error:

/usr/bin/wmamp3: line 13: -o: command not found


again the product of this is named .mp3 but won't play. surely someone has to have this same problem???

try to replace -ao pcm -waveheader with -ao pcm:waveheader

I don't know whether mplayer does anything as it sould, but lame obviously doesn't.

The correct command on line 13 of wmamp3 should be like "lame audiodump.wav something.mp3". But it seems as if there's a semicolon or a new-line somewhere in the middle of that. Can you post the script? Or, if it is too long, about lines 10 to 15 of it?

EDIT: Didn't see the link at the top of your post... so just ignore what I said...

why did we accept this howto in the first place?! that's a pretty crappy script i've gotta say... well post what you've currently got and we'll go from there...

@chemdawg
As there's nothing on line 13 of the script, I suppose the editor you used to save it inserted a new-line character before audiodump.wav, cause the line was too long, so it will probably work if you merge the two lines..

Anyway I wouldn't use mplayer for that, I think transcode is way better for converting.

Thanks for all the help so far. DeNayGo was right - nano wrapped the text when it shouldn't have. Fixed that and made changes suggested by acid an heema. Here's the script I have now:



#!/bin/bash

current_directory=$( pwd )

#remove spaces
for i in *.wma; do mv "$i" `echo $i | tr ' ' '_'`; done

#remove uppercase
for i in *.[Ww][Mm][Aa]; do mv "$i" `echo $i | tr '[A-Z]' '[a-z]'`; done

#Rip with Mplayer / encode with LAME
for i in *.wma ; do mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader $i && lame -m s -o audiodump.wav $i; done

#convert file names
for i in *.wma; do mv "$i" "`basename "$i" .wma`.mp3"; done

rm audiodump.wav


It still doesn't work though:

well I think we're making progress. Sorry, I don't know anything about scripts or any of the like. I'm at your mercy on this one.

BTW - is there another way of converting wma to mp3?

Yeah, there is another way. Using transcode.

Something like that should work:
transcode -i file.wma -x null,mplayer -y null,lame -o file.mp3

And, in case ffwmav2 is included in transcode's ffmpeg codec:
transcode -i file.wma -x null,ffmpeg -y null,lame -o file.mp3

You can specify the bitrate etc. with the -b parameter..

hmm.. humble pie time... read that script wrong and thought that bit about -o was for mplayer, not lame... yeah that does make sense after all :-s

Essentially you might just want to ignore the formatting of the script and such and just use this on a per file basis:

that basename part will also make blah.wma convert to blah.mp3, as it seems unless lame adds it's own suffix it'll be overwriting the original file...

acid: not sure how to use what you gave me. is that a scrip that i can make executable like the one I've been trying to use?

DeNayGo: Can't get transcode to work either. I finally got it installed though. will get back on this later

I found this script in the wiki that i also tried:

http://wiki.linuxquestions.org/wiki/.wma_to_.mp3

and that one didn't work either. Now, I'm thinking there could be something wrong with the way mplayer or lame is installed. Is that even remotely possible?
