This is the second third of the 270abc core sequence designed for the computer music graduate program. Students in other programs are also welcome. Some DSP knowledge, such as provided in 270a, will be very helpful.
This course was originally taught by Jerry Balzano and focused on cognitive processes in music listening and understanding, but since 2016 it has evolved to focus on computational models, particularly analysis of musical sound.
Over the course of the quarter I'll throw out three sonic challenges, soundfiles for you to attempt to analyze and resynthesize using techniques of your choice. Here are patches, screen movies and blackboards.
