#Requirements

• Sox: sudo apt-get install sox or sudo yum install sox.

  For support more audio formats than 'wav': sudo apt-get install libsox-fmt-all (debian).

$ cp ./audio2ascii.sh /somewhere/in/your/path  # must be in your $PATH

If you want start audio2ascii from Natron, you should run it with its gui (yad must be installed). To install the plugin AudioToAscii.py and its icon:

If you want just add a menu command to the application’s menu-bar, add the following lines in your $HOME/.local/share/INRIA/Natron/Plugins/init.py (create init.py if doesn't exist):

import os
def audioToAscii():
    os.system("audio2ascii.sh -g &")
natron.addMenuCommand("Ext-Tools/AudioToAscii","audioToAscii",QtCore.Qt.Key.Key_L,QtCore.Qt.KeyboardModifier.ShiftModifier)
