The Art and Science of Making and Playing Great Recordings— The High Resolution Experience
A listener’s emotional involvement with a recording and its reproduction depends on intangible factors such as imaging, transparency, articulation, and delineation. A brief overview shows how these features pose design and performance issues with halls, microphones, electronics, processes, and loudspeakers. Tests that fit each component are described and perceptual hearing models are introduced to interpret results. Topics, presented from a multichannel perspective, include how instruments, halls, and visual cues create a live concert experience and how microphone choices, placements, and mix-in strategies can constrict or expand a soundscape. Other topics include time corrected stereo accenting and eigensonic corrected loudspeakers for supplemental hall driving as well as reduction of loudspeaker presence and front biased imaging from playback systems.
