Μετατροπή wma σε mp3
Το πρώτο μου sciptάκι. Κυκλοφορούν πολλά αντίστοιχα στο διαδίκτυο αν δεν σας αρέσει η δική μου εκδοχή.

################################## wma2mp3.sh ##################################
# Author : Karapanagiotis Pantelis #
# Released On : Sunday 05 July 2009 #
# Version : 0.1.1 #
# Desription : Converts all wma files in the current folder to mp3 ones. It #
# is able to convert all files, independently of the characters #
# contained in their names. #
# Dependencies : This script depends on mplayer to decode the original wma to #
# a temporary wav file. Then it uses lame to encode the wav file#
# to a mp3 one. To intall the dependencies in debian derived #
# enviroments use #
# sudo apt-get install mplayer lame #
# Usage : In order to avoid copying the file to every folder you want to#
# use it, just copy it in /usr/local/bin. Give it permission to #
# be executed. Then cd to the desired folder and execute the #
# shell script using just wma2mp3.sh #
# TODO : >>keep track tags >>Let user choose bitrare. >>Enable more #
# conversions #
