- - DISCUSSION: Convert WMA to MP3 (https://www.linuxquestions.org/questions/linuxanswers-discussion-27/discussion-convert-wma-to-mp3-273400/)

This is a script I wrote to rip audio cd's into mp3 with a vbr. You can adjust or use bits as required. It's not commented in detail because I wrote it just for personal use.

Doesn't use intermediate files etc and runs fairly quick. I've not looked at the rest of this thread so it might have already been covered.

Code:

#!/bin/bash 



if [ $# -lt 1 ]

then

  echo "Usage: " `basename $0` "<output directory> [device]"

  exit

fi



if [ ! -d $1 ] 

then

  echo "$1 is not a valid directory"

  exit

fi



#Default device to /dev/sr0 unless $2 is set

if [ $2 ]

then

  device=$2

else

  device="/dev/sr0"

fi



# Need determine the number of tracks on the disc

n_files=`cdparanoia -d $device -Q 2>&1 | egrep "^ *[0-9]+\." | wc -l`



if [ $n_files -lt 1 ]

then

  echo "ERROR - Can't find any tracks - is the CD inserted?"

  exit

fi



echo -e "Ripping $n_files files..."



for i in `seq 1 $n_files`

do

  cdparanoia -d $device -q $i - | lame --silent -h --vbr-new -V 4 - `printf "%s/track_%02d.mp3" $1 $i`

  echo  - Sucessfully ripped track $i

done



echo "Ripping complete"

At all costs, we must always try to avoid reinventing the wheel. There is a lightweight commandline program that can rip files from audio CD to MP3 or OGG formats AND fetch track metadata (tag info) from the internet (ie CDDB/Gracenote) for the entire album. It's name is abcde and is available via synaptic in 'ubuntu'. Further configuration can be customized via /etc/abcde.conf.

Cadjs code that is:)

this should go without saying, but make sure to make a copy of your wma files if you want to keep them as is. :)

Could someone tell me, please, how exactly do I do step 5:

"5. as root, copy the file to your exec path (/usr/bin or /bin)"

Kind regards

I ge the new file but no audio

I have followed your instructions but still get no audio.
The following is the output from my terminal after executing. I don't the file is converted, just renamed.

james@local ~/Desktop/convert /Disintegration $ wmamp3
mv: `Closedown.wma' and `Closedown.wma' are the same file
mv: `Disintegration.wma' and `Disintegration.wma' are the same file
mv: `Lullaby.wma' and `Lullaby.wma' are the same file
mv: `Plainsong.wma' and `Plainsong.wma' are the same file
mv: `Untitled.wma' and `Untitled.wma' are the same file

Somewhat Dangerous Script

Back up your data before running this script, because on error it destroys the files it runs against. I ran the script with a newer version of mplayer, which had a different switch (specifically, `-waveheader' is now `pcm:waveheader'). However, renaming the files - without performing the conversion - still takes place! Luckily I have a backup. Do you? ^_^

I had made a script for converting audio files to and from MP3, WMA, OGG, AAC, FLAC, WAV. It is fairly safe as files are not removed if you dont want them to and existing files are not overwritten if you dont want them to. All the metadata tags (song information) are preserved (ie not lost) when converting to another format.

You can read more about it on its official googlecode website: http://code.google.com/p/ftransc/

@ jamessp007

I had the same problem and the answer is in the error message. The newer version of mplayer uses different tags. A slight adjustment of the command line under #Rip with Mplayer took care of that.

@ egarson

An extra line in the script can do the backup for you. See the code under #make copies of original files.

Here is the script I'm currently using to convert wma-files of sound files I download from a web-server with mmsrip. My version of mplayer is SVN-r31628-4.4.4.

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



#make copies of original files

for i in *.wma; do cp "$i" "`basename "$i" .wma`.tmp"; done



#Rip with Mplayer / encode with LAME

for i in *.tmp ; 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 *.tmp; do mv "$i" "`basename "$i" .tmp`.mp3"; done



rm audiodump.wav

Hope someone will find this useful.
Cheers
