This talk was given by undergraduate James Norton during the 8th Annual Computer Science Undergraduate Research Symposium in 2014. James‘s research was supervised by Dr. Ming Lin.
"Audio Signal Representations For Sound Design"
Despite sophisticated models of representing sound, modern software synthesizers rely heavily on analog-modeled hardware in their design. This leads to proliferation of control parameters which is evidenced by the user interface of many synthesizers. By representing audio as a path through the space of power spectral density functions, control parameters can more directly relate to perceptually important features. This creates a more streamlined process, allowing users to focus more on the sound than on the signal flow used by the implementation.
James Norton is a Chapel Hill resident who began research with Dr. Ming Lin last spring. His technical interests include digital audio, computer graphics, and math. As a musician for over 15 years, James has found digital audio to be a natural way to combine many of his passions.
