Homework #1: iPhone: Get Set, Synthesis, Interact

Due date: 2009.1.13 11:59:59pm (or thereabout), Wednesday.


The goal of the first homework is to make sure everyone can get real-time audio up and running with some interaction with external control such as input from the accelerometer, compass, multi-touch, or GUI elements. Let's get cookin'.

Specification (part 1 of 3): Get Set Up

-Compile and run a standalone program on your phone. Simply build own of the iPhone template projects, compile, and run on the phone (not just in the simulator). -Take the basic Basic audio I/O (should be review from the tutorial)

Specification (part 2 of 3): Synthesize Audio


Specification (part 3 of 3): Interaction


  • have fun with it!!!
  • comment your code!
  • choose your own coding conventions - but be consistent
  • you are welcome to work together, but you must do/turn in your own work
  • some considerations:


turn in all files by putting them in your Library/Web/256b/hw1/ directory, and concise online documentation + readme

  • 1) source code to the project (*.h, *.cpp, *.m *.mm *.c makefile, project files, etc.)
  • 2) online page for your project (should be viewable at http://ccrma.stanford.edu/~YOURID/256b/hw1/). It should include:
    • links to your files of various kinds (or to a zip/tar archive)
    • instructions on building the project (for example, anyone in the class should be able to download and run)
    • a short README text section that:
      • conveys your ideas/comments in constructing each program
      • describes any difficulties you encountered in the process
      • lists any collaborators
  • 3) email Ge and Nick with the link to your web page, as a confirmation that you are submitting the assignment
