D. P. W. Ellis, D. F. Rosenthal


In this paper we consider representations for use in models of the processing that occurs between the eardrum and our conscious experience of sound. We first list `good' properties for such mid-level representations, then present a framework within which to discuss some examples. We compare in detail two popular schemes -- sinusoid tracks and correlograms -- and propose a new representation, wefts, which seeks to combine their advantages.
