Some ideas for non-composition projects:

• Port ein to a PC (multi-person project).
• Study apparent aliasing in sunlight (or moonlight).
• Measure the Doppler effect when a tuning fork is spun on a motor shaft, and compare with theory.
• Study the noise in simple signals (like single sinusoids) displayed in ein when dB display is used in the spectrograph window. Perhaps try to remove the original cause and listen to the boise alone.
• Study waves on a string for which the speed of propagation is different in the two directions, or for which there are more than one possible speeds.
• Sonify soliton collisions in non-integrable (continuum) systems (click here for more on solitons from ken's home page).
• Study synesthesia in the context of sound perception. For a classic case study see

• Investigate the noise remaining after a sine wave is removed with a feedforward filter.
• Study application of wavelets to sound analysis and synthesis.
• Study sound localization and 3 dimensional sound.
• Model sympathetic string vibrations, as in a sitar.
• Study the rate at which the tuning of a plucked-string filter can be varied, and the effects of changing the tuning too fast.
• Study the ways in which the timbre of the attack of a pluck string filter can be varied, and also figure out how to make the rate of decay (relatively) independent of the frequency.
