Pure Data (Pd) is the a real-time graphical programming environment for audio and graphical processing written by Miller Puckette. It is the software I primarily work with and you can find more about it at www.puredata.info.

Here is my paper from the Pd Convention 2007 in Montreal/CAN about the ArduinoI board and Pd. Pduino and other Arduino Interfaces for Pd

FFT - Some words about Fourier Transformation in connection with Pd
FFT and PD english

Pd patches - Some abstractions and useful patches
