SESSION 4: CREATING SPACE WITH DSP


Coloration in Natural and Artificial Room Impulse Responses
Per Rubak and Lars Johansen
Aalborg University, Aalborg, Denmark


A literature review concerning perception of coloration is presented. In the paper we also present a review of general psychoacoustic background material concerning auditory modeling including perception of timbre and amplitude modulation. Also some classical room acoustic measures for echo perception are considered. Finally some of the simple engineering measures to rate coloration is evaluated, and an auditory signal processing model including a combined time-frequency detection criteria is presented.
