MP3 encoder with image processing

README.markdown

Wave to Mp3 encode

This is folder based encoder script written in bash/zsh that allows you to encode bunch of Wave files to MP3 with ID3 and embedded artwork.

Protocol

• Script has to be ran inside of the folder named: CATALOGUE####] Artist Name - Album Name

• The structure inside forlder should look like that: Artist Name - Track name.wav Track itself CATALOGUE####.jpg artwork for the release (any size) it will resize it to 300x300 anyway}

How to use

Simply make it executable and run inside of the folder.

% chmod +x mp3enctag Drop this file in folder with wave files and artwork.jpg you need to process % ./mp3enctag

You could also use apple automator in order to automate the process
