1925: Western Electric / Bell Labs electrical recording

evidence

Western Electric licensed the Bell Laboratories electrical recording system to Victor and Columbia in 1925; Victor contracted in March and issued its first electrical orchestral recording in April; the Harrison and Maxfield matched-impedance recorder handled roughly 50–6,000 Hz against the acoustic process's roughly 250–2,500 Hz. V55 verification basis: retrieved in search summary attributed to this technical history; the article was not opened, no Bell Laboratories or company record was consulted, and the frequency figures should be read as approximate.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
