AES Convention 123 · Paper 7233 · October 2007

Abstract

Microphone technique for surround sound recording of an orchestra is discussed. Eight types of well known microphone array recorded in a concert hall were compared in subjective listening test on seven attributes such as spaciousness, powerfulness and localization using a method inspired by MUSHRA (MUltiple Stimuli with Hidden Reference and Anchor). The result of the experiment shows similarity and dissimilarity between each microphone array. It is estimated that directivity of a microphone and distance between each microphone are related to the character of microphone array and these similarities are changed by music character. The relations of the physical factors of each array were also compared, such as SC (Spectral Centroid), LFC (Lateral Fraction Coefficient), and IACC (Inter Aural Cross-correlation Coefficient) from the impulse response of each array or recordings by a dummy head. The correlation of these physical factors and the attribute scores show that the contribution of these physical factors depends on music.
