= Homework #3: "Granular" =

* milestone+ '''due 2022.2.23 Wedesday, in-class'''

In this assignment, you are to explore and make use of Granular synthesis: 1) experiment with time-varying control over its parameters and 2) create a musical statement (milestone+ only);  it may be helpful to craft a live granular experimental testbed using physical input (keyboard, mouse, and/or joystick).

=== Tools at your disposal ===

* ChucK
* [http://chuck.stanford.edu/doc/program/ugen_full.html#LiSa LiSa] (Live Sampling); use multiple instances for layering / panning OR roll your own granularizer!
* check out [https://ccrma.stanford.edu/courses/220b/ck/twilight-redux-kb.ck instrument redux] and [https://ccrma.stanford.edu/courses/220b/audio/twilight-source.aiff source sound] from [https://vimeo.com/100624271 Twilight] for laptop orchestra | (also the game-trak version: [https://ccrma.stanford.edu/courses/220b/ck/twilight-trak.ck twilight-trak])
* recorded sounds (any, please give proper credit)
* Audacity/Ardour (for intermediate + final recording/assembly)

=== Specification ===

What to do:
* 1) spend some time exploring and collecting different sounds (online or recording them; check out [http://freesound.org/ freesound.org])
** give proper credit as appropriate / note the origin of the sounds in your README
* 2) process/transform/arrange/compose.
** check out the code examples from class [https://ccrma.stanford.edu/courses/220b/lectures/ here]
** use ChucK / LiSa to process/transform/arrange the sounds
** plan and create time-varying, continuous control over '''at least 2''' parameters in the synthesis process (grain length, grain tuning, grain position, volume, envelope, density, or other)
* 3) think about using granular synthesis to create foreground musical gestures, soundscapes, layers
* 3) as before the bulk of the arranging should be done in ChucK, with intermediate editing and late-stage assembly in Audacity
** figure out what you want to do, experiment, try a lot of stuff, have fun

=== Deliverables ===

'''As usual, add to your portfolio — and turn in all files to Canvas'''

* 1) all related source/sound files (.wav/.ck)
* 2) a short README text ('''readme.txt''') file that:
** specifies instructions on running your programs
** describes your process/adventure, and perhaps the ideas (technical/aesthetic) behind the composition
** gives credit, if needed, for the sounds you are using
** describe any difficulties you encountered in the process
* 3) upload files to webpage / Canvas

Good luck and have fun!
