This assignment required us to use fft- an object that segregates the different frequencies a signal is composed of. So, I used Alvin Lucier’s “I am sitting in a room” audio signal and got rid of frequencies above a certain threshold. I then delayed this signal and added feedback. This added a certain villainous tone to Alvin’s voice. I also modified the patch we made in class to create an audio visualizer that visualized the audio signal before and after the fft manipulation.
The code for the main pfft~ can be found here:
