Auditory Textures

Texture properties could be captured by summary statistics that are time-averages of acoustic measurements. We have explored the hypothesis that the auditory system represents textures in this way, with statistics of the measurements made in the peripheral auditory system.

Source Repetition Stimuli

We used a simple generative model to synthesize novel sounds with naturalistic properties. We found that such sounds could be segregated and identified if they occurred more than once across different mixtures, even when the same sounds were impossible to segregate in single mixtures.

Sound Contour Demos

A study of relative pitch - the relationships between the pitch of successive sounds - to determine whether properties of relative pitch would generalize to other auditory dimensions.

Spectral Completion of Paritally Masked Sounds

The auditory system uses the audible portions of an object's spectrum to infer the portions that are likely to have been masked, and that are thus not veridically present in the input to the auditory system.
