Lab 8 - Additive Synthesis This lab uses the Fast Fourier Transform (FFT) to show the spectrum of a waveform. It was adapted from an example in the PD library. Use your own paper to answer the numbered questions below and turn it in on 4/9. There is no worksheet for this week, instead there are 3 points for answering the questions in the lab and 3 points for turning in the pd patch. The quiz on 4/9 will cover the equation M=LRSC (end of Chapter 4 of the Wright, Fundamentals of Digital Sound ), and the information on sound synthesis modules, fixed waveform synthesis and additive synthesis on pages 5-8 of Chapter 5. We will go over this information again at the start of class on Friday before the quiz, so bring any questions you have. Open the file “08_Spectrum.pd” and click the START button. You should hear a sine tone, and see its waveform in a box. Above the waveform display is a graph of the spectrum of the sound. Normally you would see a single peak in the spectrum because that is the nature of a sine wave. This example has two because the waveform has had a DC offset added to it in order to perform do the reshaping of the waveform that happens
