Alan Blumlein's pioneering work in stereo sound reproduction, patented in 1931, focused on using two independent audio channels to achieve what specific listening quality?

Answer

A more realistic, spatial sound field

The core contribution of Alan Blumlein's stereo invention was the establishment of spatial realism in sound reproduction. By employing two independent audio channels, his patented method allowed listeners to perceive depth and directionality in the soundstage, simulating a more natural acoustic environment than previously available monaural systems. This dedication to high fidelity and realistic sound staging established a benchmark for audio quality that subsequent whole-house systems were expected to maintain as they evolved to distribute that quality signal across multiple physical areas.
