Acoustic Requirements of Stereo Recording Studios
The need for a high degree of acoustic isolation between multiple channel pickups in the recording of stereophonic sounds has emphasized the need for not only close up directional microphone and lower reverberation times but a more careful consideration of the disposition and orientation of all reflecting surfaces which give rise to early or short time reflections in the environs of the microphone pickups, the original sound sources and performers. Accordingly, this paper reviews the basic requirements of good studio acoustic design from the viewpoint of the control of the early reflected energy as well as the control of the direct and reverberant energy components in the studio space. The paper also includes comments on control room acoustics and monitoring loudspeaker placement.
