Abstract
Room equalisation aims to increase the quality of loudspeaker reproduction in
reverberant environments, compensating for colouration caused by imperfect room
reflections and frequency dependant loudspeaker directivity. A common technique
in the field of room equalisation, is to invert a prototype Room Impulse
Response (RIR). Rather than inverting a single RIR at the listening position, a
prototype response is composed of several responses distributed around the
listening area. This paper proposes a method of impulse response prototyping,
using estimated receiver positions, to form a weighted average prototype
response. A method of receiver distance estimation is described, supporting the
implementation of the prototype RIR. The proposed prototyping method is
compared to other methods by measuring their post equalisation spectral
deviation at several positions in a simulated room.
