Bash script to convert a list of files to MP3 format.

convertToMp3.sh

#!/bin/bash

# Converts a list of files to mp3 format
# uses avconv, and requires ubuntu-restricted-extras package for the libmp3lame encoder.

# Example usage of this script:
# ./[scriptname] ./file_list.txt

# Notes on this script:
# - !!!IT DELETES THE INPUT FILE!!! (you can remove the line below in the do loop that rm's the input file)
# - Specifies max bitrate of 192k
# - Uses mp3 tags version id3v2.3, not the default 2.4 version. This makes it more compatible, especially
#   with Windows.

# To create a list of files, use a command similar to this find command, which searches the current
# directory (.), for files that have a name ending in ".wma" (example for converting WMA to MP3):

# find . -type f | grep -e "\.wma$" > file_list.txt


# -- Begin Script -- #
file_list=$1

while read input_file;
do
  output_file="$(echo $input_file | head -c -5).mp3"
  avconv -y -i "$input_file" -maxrate 192k -acodec libmp3lame -id3v2_version 3 "$output_file"
  rm "$input_file"
