Homework #2: "Granular"

• milestone due 2016.2.2 Tuesday, in-class
• final composition due 2016.2.8, Monday, 11:59:59

In this assignment, you are to explore and make use of Granular synthesis: 1) imposing time-varying control over its parameters and 2) creating a live granular experimental testbed using physical input (keyboard, mouse, and/or joystick).

Tools at your disposal

• ChucK
• LiSa (Live Sampling); use multiple instances for layering / panning OR roll your own granularizer!
• check out instrument redux and source sound from Twilight for laptop orchestra
• 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 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 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, turn in all files by putting them in your Library/Web/220b/hw2/ directory + uploading to coursework

• 1) create a hw2/ directory, and put all the stuff below in there:
• 2) all related source/sound files (.wav/.ck)
• 3) 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
• 4) upload files to dropbox on coursework
• 5) email Ge and Tim (ge@ccrma, tsob@ccrma) with the URL of the web page

Thanks and have fun!!!
