[vc_row][vc_column][vc_column_text]I need to convert 3 DVD contain .WAV file to .MP3. I prefer command line way.

In my Ubuntu 14.04 install FFMPEG

sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next
 sudo apt-get update
 sudo apt-get install ffmpeg

Go to the Wav folder and run this command

cd wav/
 for file in *.wav
 do ffmpeg -i "${file}" "${file/%wav/mp3}"
 done
 mkdir mp3dir
 mv *.mp3 mp3dir

Done![/vc_column_text][/vc_column][/vc_row]
