I am going to install lame but what is the go with waveheader.

Just edit the script and modify -ao pcm -waveheader with -ao pcm:waveheader, or even better take a look at the python script. (link is six, seven topics above).

so do i just copy the code and put it in the editor??? or do i have to change stuff

Or you could just download Audacity and use its export tool.

Not trying to steal the OP's thunder here, but with Audacity you have an app that can do a whole lot of groovy things.

Excellent script! Easy to use and ran without a hitch

Thanks a bunch!

OK - i fixed it - you might find this a bit better:

Code:

for i in *.wma
do
	filename=`basename "$i" .wma`
	
	#Rip with Mplayer / encode with LAME
	echo "Ripping $i"
	mplayer -quiet -vo null -vc dummy -af volume=0,resample=44100:0:1 -ao pcm:waveheader "$i" 
	echo "Encoding $i to "$filename".mp3"
	lame -quiet -m s audiodump.wav -o "$filename".mp3

	rm audiodump.wav
done

Proper use of quotes removes all that need to convert spaces...

Can .WMA format be converted to .MP3 format with mplayer without losing quality of the sound and file?

fakie_flip · 09-20-2005, 09:10 AM

I guess that I will not be able to use mplayer to convert my .WMA format files to MP3 format files because they are on an ntsf partition, and it is read only to Linux(about 15 gigabytes of music). Windows updater came and changed all my music to .WMA format files without my permission by trying to be proprietary.

cadj · 09-20-2005, 10:32 AM

I had no issues with sound quality at all, as far as your NTFS partition goes, why not convert them on your linux partition, then burn the new mp3's to a cd(s) or dvds, then boot into windws and copy them back?

JamieBrown · 09-20-2005, 06:11 PM

The theory is that converting from any compressed format to any other compressed format will reduce quality because of the ways that the compression methods differ with each format. If you have a look at the offical Ogg Vorbis site it will explain that in some depth.

But as per cadj, I've never *noticed* any difference when I've done it. Regarding playing your WMA files - it is possible to play WMA in Linux, just a little awkward. The main problem I came across was that amaroK could play them, just wouldn't add them to the "Collection" section. But you can always play WMAs from mplayer on the command line, and there's probably other pretty clients like amaroK that will play them nicely for you. (Although I don't know of any, because I always use amaroK!)

Anyway, good luck!

i tried running this, as i have a whole bunch of .wma's i want to convert into .mp3's (actually, i'd really love to use vorbis, but .mp3 is find for now). however, i get this error:

i've tried just using audacity, but all i get when i import a .wma is a bunch of static (plus, i'd like to be able to convert them all at once).

am i missing something really obvious, or?

cadj · 09-27-2005, 09:24 PM

show us your script.

it seems like mplayer is trying to read a file called "*.mp3"

kokoba · 09-27-2005, 10:46 PM

sorry about that. here's what i have in /usr/bin

Code:

#!/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 audiodump.wav -o $i; done

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

rm audiodump.wav

thanks so much--i am ridiculously incompetent without my free tech support/boyfriend.

cadj · 09-27-2005, 11:03 PM

dibblethewrecke has made this a lot easier, by explaining that using quotes removes the need to remove spaces and uppercase, have a look, this may work for you.

Code:

for i in *.wma
do
	filename=`basename "$i" .wma`
	
	#Rip with Mplayer / encode with LAME
	echo "Ripping $i"
	mplayer -quiet -vo null -vc dummy -af volume=0,resample=44100:0:1 -ao pcm:waveheader "$i" 
	echo "Encoding $i to "$filename".mp3"
	lame -quiet -m s audiodump.wav -o "$filename".mp3

	rm audiodump.wav
done

if you have many folders/subfolders with wma's, use this at the top instead

Code:

for i in $(find -iname *.wma); do

this runs the 'find' command and processes the outputs

kokoba · 09-28-2005, 03:27 PM

that works great, thank you!
