Music in Our Ears: The Biological Bases of Musical Timbre Perception
Figure 7
Model musical timbre similarity.
Instrument similarity matrices based kernel optimization technique of the (A) neurophysiological receptive field and (B) cortical model receptive fields. (C) Control experiments using the auditory spectral features (left), separable spectro-temporal modulation feature (middle), and global modulation features [separable spectral and temporal modulations integrated across time and frequency] (right). Red depicts high dissimilarity. All the matrices show only the upper half-matrix with the diagonal not shown.
