- High-Performance computer music - Many non-real-time audio computations could be in the reach of a real-time system with the appropriate signal processing and systems work. Heavily Fourier-based filter graphs and 3D positioning calculations are CPU-bound processes that would benefit from careful model reduction and/or parallelization.
- Virtual Instruments - We have not yet discovered good mappings for gestural
control to be used as an instrument, instead of as a toy. A good virtual
instrument could also use a 3D visualization component to provide additional
feedback to the musician. Possible projects include an extension of McAdams
timbre space to a playable system. We can also identify that just about every
likes to pretend to conduct when they hear an orchestra or air guitar to the
radio. How about a system that lets you conduct your own virtual orchestra? We
could also derive an empirical user pitch space to let everybody play virtual
- Audio Rendering - As with graphical rendering, run a simulation of the
propagation of sound within a space. A primary application is to provide
for 3D sound when the viewer moves in a virtual world. One could also produce
a view of what is heard by other characters within the same world. A
moderately-sized cluster would provide enough cycle time to do such a
simulation. Systems work to provide soft real-time behavior would also be
- Sound Design for Virtual Environments - What cues are needed to make a world
more convincing? What audio behaviors are needed? Cues such as audio distortion,
damping, and the Doppler effect provide us contextual information that is
largely absent from current simulations.
- Granular Synthesis - Is it possible to write a high-level description that
can be used algorithmically to produce a requested signal at the micro scale?
Can we write high-level composition tools that produce output compilable to
millisecond-level specifications? We should be able to have a single computer
instrument that is capable of sounding like any instrument from one moment to
- Wavelet processing of audio - What advantages are afforded by processing
in the wavelet domain? Can we eliminate some artifacts of Fourier domain
transformations? Can we think of new transformations in this domain?
