ABSTRACT
This paper faces the general problem of modeling pinna-
related transfer functions (PRTFs) for 3-D sound render-
ing. Following a structural modus operandi, we exploit an
algorithm for the decomposition of PRTFs into ear reso-
nances and frequency notches due to reflections over pinna
cavities in order to deliver a method to extract the frequen-
cies of the most important spectral notches. Ray-tracing
analysis reveals a convincing correspondence between ex-
tracted frequencies and pinna cavities of a bunch of sub-
jects. We then propose a model for PRTF synthesis which
allows to control separately the evolution of resonances
