Homework #3: Sound Peeking

Due date: 2008.11.24 11:59:59pm (or thereabout), Monday.

(F)AQ

In this assignment, you are to visualize sound in real-time, using OpenGL for the graphics programming.

Specification (part 1 of 3): naming + compilation

choose a name for your program
get a framework compiling on your system (keep in mind the final deliverable must be compilable/runnable on the CCRMA machines OR on OS X)
might wish to start from the VisualSine example from lecture (time domain waveform rendering)
additional code from class available here

Specification (part 2 of 3): Visualizing the spectrum

implement short time fourier transform, and visualize the spectrum over time
considerations:
- windowing (rectangular, hann, hamming)
- window size
- FFT size
- hop size (for now, hop size can equal window size)
implement either a waterfall plot (like sndpeek) or a real-time scrolling spectrogram

Specification (part 3 of 3): Visualize something about the sound

implement and visualize your choice of one of the following:
- vowel vs. consonant
- pitch tracking
- an audio feature
- use the sound to control some type of animation
- (or something of your choosing)

Note

have fun with it!!!
your code should compile and run on the CCRMA (or OSX) machines
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 (you'll likely get more out of it this way)

Deliverables

turn in all files by putting them in your Library/Web/256/hw3/ directory, and concise online documentation + readme

1) source code to the project (*.h, *.cpp, *.c makefile, etc.)
2) online page for your project (should be viewable at http://ccrma.stanford.edu/~YOURID/256/hw3/). It should include:
- links to your files of various kinds
- instructions on building the project (for example, anyone in the class should be able to download
- 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 with the link to your web page, as a confirmation that you are submitting the assignment
