Homework #2: "Granular"

  • milestone due 2015.2.3 Tuesday, in-class
  • final composition due 2015.1.9, 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

(note: these are the only tools you are to use (but you don't have to use all of them) - you'll need to obtain permission to use other software or sound samples you didn't record)

  • ChucK
  • LiSa (Live Sampling); use multiple one for laying / panning OR roll your own granularizer!
  • 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, density, or other)
    • 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.

  • 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) please email Ge and Alex (ge@ccrma, chechile@ccrma) with the URL of the web page


Thanks and have fun!!!
