28-Oct Non-linear dynamical systems: algorithmic composition and physical modeling

- audio feedback, room in a room in a room...

I am Sitting in a Room, Alvin Lucier (1969)

impulse responses of spaces

I am Sitting in a Silo, 220a

- Lecture on instruments as non-linear dynamical systems, aka linear resonators coupled to non-linear excitation mechanisms (bows, reeds, etc.)


code examples used in lecture

- musical feedback, singers with the sounds of singers with the sounds of singers...

Tuning Meditation, Pauline Oliveros (1971)

different performance, binaural recording

[xxx code from final project inspired by Tuning Meditation, Chris Vega] copy paste and then run in webchuck

[xxx .wav file from 2007]

7-Oct Modulation & Delay

- FM & web audio

(from codelab )

tremolo / vibrato / filter / ADSR / FM

DX7 FM synth, web audio emulation

- FM & Chuck (hw2)

paste code from hw2 starter code into webchuck and run it

- Ambisonics, source position and reverb

download 4 .wav files produced by my modified hw2 starter codes, which I stashed here

start the 220a ambisonic-recorder and load those 4 files

experiment with source position, reverberation and wall materials

- Wave physics simulator

go to rippletank Example: Internal Reflection, and experiment with waves and reflection off a wall in 2D

wavebox visualizes 3D waves (no reflections)

interactive filters with sound

interactive stretched string with sound

28-Sep Sonification

(written in chuck and exported to .wav file)

tides slow

tides fast

jamming with tidal sonification

(written in web audio and played live in browser)

tides fast

compare visual + auditory

environmental and brain wave examples
