Read the project description carefully. Questions and comments can be sent to

General information

The purpose of the project work is to get hands on experience and deeper understanding on one specific area of the course. At the same time you will be forced to think on some of the more general issues that are confronted every time a visualization method is developed or used.

To complete the project you will probably need information that has not been discussed on the lectures or in the exercises. Most of the time relevant information can be easily found on the web, course books or in some cases references to articles will be given. If you have problems finding information on the subject please contact the lecturer or the assistant for hints and guidance.

The project work will be valid for one year after the original deadline.

General requirements

specific requirements

The purpose of this project is to apply sonification to program profiling.

  1. Sonification is useful to analyze time-dependent information and to enhance visual information. The sonification also offers an additional input channel that is independent of vision.

  2. Make a debugger that gives different kinds of sounds depending on what the program is doing. (Obviously you should run your program slower that at one gigahertz).

  3. If necessary, combine the sonification with the visualization of the executing program code.

  4. Try to design your profiler so that you can hear e.g. which parts of your program code take most of the time.
