This is based on How to Convert Unprotected WMA Files Into MP3 Files. I’m leaving the instructions here for my future self. 😄
How to Convert Unprotected WMA Files Into MP3 Files
for file in *.wma; do
mplayer -vo null -vc dummy -af resample=44100 \
-ao pcm:file="${file.[Ww][Mm][Aa]}.wav" "$file"
lame --preset standard "${file.[Ww][Mm][Aa]}.wav" \
"${file.[Ww][Mm][Aa]}.mp3"
done
Use `locate lame|grep 'lame ` and `locate mplayer|grep 'mplayer ` to find the location of your executables. On a Mac, they’re probably not on your PATH... I installed *MPlayer OSX* and *iTunes-LAME* to get the executables. You’ll need to do something similar.
This is the result I just used for some files with upper case file extension:
for file in *.WMA; do
"/Applications/MPlayer OSX.app/Contents/Resources/External_Binaries/mplayer_intel.app/Contents/MacOS/mplayer" \
-vo null -vc dummy -af resample=44100 \
-ao pcm:file="${file.[Ww][Mm][Aa]}.wav" "$file"
"/Applications/iTunes-LAME.app/Contents/Resources/lame" \
--preset standard "${file.[Ww][Mm][Aa]}.wav" \
"${file.[Ww][Mm][Aa]}.mp3"
done
