In the Light of 5.1 Surround: Why "AB-Polycardioid Centerfill" (AB-PC) is Superior for Symphony-Orchestra Recording

Document Thumbnail

Abstract: The reappearance of surround sound in the form of the DVD's 5.1 format has led sound engineers to re-evaluate current microphone techniques used for stereo recording. The author has measured various 2-channel main-microphone signals in order to prove that their correlation is strongly frequency dependent. Due to properties of the human hearing mechanism as well as standard loudspeaker playback-arrangements frequencies below approximately 800 Hz are particularly critical in terms of faithful spatial reproduction in a stereo as well as 5.1 surround environment and therefore deserve special attention already during the recording process. Conclusions from the measurements are drawn and a microphone system ("AB-Polycardioid Centerfill"), well suited for 5.1 surround is proposed.
