Abstract

This paper describes a soon to be available system for stereo hi-fi use for equalising room and loudspeaker impulse responses across a listening area, using a chirp measurement and decimated digital equaliser implemented using a single DSP chip per channel. Filter impulse response lengths of up to one second are achievable at low frequencies. Psychoacoustic requirements are discussed for subjectively satisfactory results and naive strategies, such as mean-square optimisation or minimum-phase equalisation are found to be inadequate.
