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).


== Overview ==
<div style="text-align: left;">[[Image:MultiGrains.jpg|700px]]</div>
Compose a short piece using the following 2 elements:


component 1:
=== Tools at your disposal ===
* a generative drum machine (think about input parameters to control/influence the drum machine; as well as ways to control these parameters)


component 2:
* ChucK
* generative soundscape (integrating algorithms to generate/modify the structures of sounds)
* [http://chuck.stanford.edu/doc/program/ugen_full.html#LiSa LiSa] (Live Sampling); use multiple instances for layering / panning OR roll your own granularizer!
* interactive control (integrating devices such as game controller, wii remote, microphone, keyboard, mouse, etc.)
* 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
* note: elements in category 2 should be used to control ''patterns'' and ''structures'' of music, not simply pitch or timbre (as if it were an instrument).  
* recorded sounds (any, please give proper credit)
 
* Audacity/Ardour (for intermediate + final recording/assembly)
== Specifications ==
* create a software system in ChucK that generates music "automatically" or "semi-automatically" (i.e., with limited "high-level" human interaction)
* consider using some of the synthesis elements we talked about (e.g., SinOsc, TriOsc, SqrOsc, Noise, Impulse, Step, ResonZ, OnePole, OneZero, BiQuad, LPF, HPF, ADSR, STK instruments, Comb filters, SndBuf, Granular/LiSa etc.)
* consider using some of the technique we talked about (e.g., shreds, events, chance, lookup tables etc.)
* potentially expose some high level parameters (e.g., density, excitement, mood, texture) and control them using input
** for example: mouse, keyboard,
** (optional): use audio analysis as a control for the synthesis (e.g., using ChucK Unit Analyzers)
* here are some example ideas (you can use, combine, extend these, or go with something else altogether)
** modeling playing style of something percussive, or a group of instruments ("real" and/or imagined)
** model a particular musical style
** leverage or musically sonify a mathematical model or a computer algorithm
** a system that somehow evolves over time, giving a set of starting parameters
** incorporate an auditory illusion, or perhaps the saliency of the voice
** invent something new/crazy!
* it might be helpful to design/partition your system into modules that you can exert independent control over, or that take care of different types of tasks/sounds in the system
* create/perform a composition using your system, paying attention to overall form, density, and texture throughout (think "sonic clouds"...)

=== Specification ===


Not all of these are directly relevant, but may serve as basic building blocks...
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

Homework #3: "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/hw3/ directory + uploading to coursework

  • 1) create a hw3/ 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!!!
