ABSTRACT
This paper considers the general problem of modeling pinna-
related transfer functions (PRTFs) for 3-D sound render-
ing. Following a structural approach, we present an algo-
rithm for the decomposition of PRTFs into ear resonances
and frequency notches due to reflections over pinna cavi-
ties and exploit it in order to deliver a method to extract the
frequencies of the most important spectral notches. Ray-
tracing analysis reveals a convincing correspondence be-
tween extracted frequencies and pinna cavities of a bunch
