There are lots of tools that to convert a MP3 file into WAV format. I recommend mpg321 which is a free command-line mp3 player, which uses the mad audio decoding library. Install mpg321 or mpg123 Type the following command under Debian / Ubuntu Linux, Use:
1 2 3 | sudo apt-get install mpg321 |
OR
1 2 3 | sudo apt-get install mpg123 |
I recommend using mpg123 as it is updated frequently. Install mpg123 under CentOS / RHEL / Fedora Linux Turn on rpmforge repo and type the following command:
1 2 3 | yum install mpg123 |
Convert an MP3 to WAV The -w option will convert an .mp3 file to .wav file. The syntax is:
1 2 3 | mpg123 -w output.wav input.mp3 |
OR
1 2 3 | mpg321 -w output.wav input.mp3 |
A Sample Shell Script Helper Function Add the following to your ~/.bashrc startup file: Open your .bashrc file and put this code at the end of the file.
1 2 3 | $ vi ~/.bashrc |
1 2 3 4 5 6 7 8 9 10 11 | mp3towav(){ [[ $# -eq 0 ]] && { echo "mp3wav mp3file"; exit 1; } for i in "$@" do # create .wav file name local out="${i%/*}.wav" [[ -f "$i" ]] && { echo -n "Processing ${i}..."; mpg123 -w "`echo $out|sed -e s/\.mp3//`" "$i" &>/dev/null && echo "done." || echo "process failed."; } done } |
Then execute the .bashrc file using source command to make changes.
1 2 3 | $ source ~/.bashrc |
Use it as follows:
1 2 3 | mp3towav *.mp3 |
