For the display module you can use pygame, pyglet or pyOpenGL, there are
fast.

For the audio analysis i thought the module must be written in C or
something very fast, because python, due to it's nature, would probably
not compute spectrum as fast as real time : 44100 samples per seconds is
a lot of work...
