It is poorly written, inefficient and may not work on other systems. The script works on my computers using Ubuntu 13.04 (and 12.04). I created it to demonstrate the conversion process and to be able to compare audio encoded with different codecs. The following is a Bash shell script that uses ffmpeg (or avconv) to convert an audio file such as a PCM/WAV file to different formats using different codecs (e.g. Converting Audio to Multiple Formats using ffmpeg or avconv
