Computational Audition
My research focuses on the analysis of sound structure. I aim to identify the intrinsic acoustic dimensions that govern the structure of environmental sounds (i.e., natural sounds that humans are exposed to in their daily life). In addition, I aim to identify which of these dimensions are relevant to the auditory perception of environmental sounds. The identification of such dimensions provides information about the features that must be preserved in audio compression, as well as about the features that must be manipulated in audio synthesis.
