Please note that the wiki does not understand the file extension .py for python programs. It makes the python programs text files. This is not a real issue, since python programs will display properly as text files.

Sample Code From Lectures

Sound Examples

• lect1129b.py.txt - Normalize a sound (make it a loud as possible without causing clipping)
