Background noise and plane noise I used the keyboard knob to control the noise controller to create background noise based on the changes in the film. I saved this recording as “noise.wav” and added it to the movie clip. 2. Part of the background ambient music I used three sawtooth wave phasor~ oscillators, combined with…

Filter Oscillators Amplitude Envelopes Sub patches To create a new object, it is called “pd xxx”, and then a new window will open. I’ll copy the relevant parts of the patch that I want to encapsulate in that sub patch and paste them into the sub patch. In order to communicate with the sub patch,…

Slider, random, and mute FM Synthesizer FM(frequency modulation) Frequency modulation needs a carrier signal and a modulation signal. The modulation signal acts on the frequency of the carrier wave, not its amplitude. The characteristic of FM synthesis is that it can easily generate rich harmonics, and we can control the components and proportions of harmonics…

Tools in pure data Oscillators and Oscilloscopes Additive Synthesis Theory： Define the frequencies and amplitudes of different harmonics and mix them together to form a new sound. Create on Pure Data This part uses random to randomly generate any integer from 0 to 100 to control the main frequency. Toggle is the switch and metro…
