Very interesting tech.. but the title seems misleading? I saw no mention of reconstruction of sound from those ranging systems recordings, instead:

> our reconstruction uses contemporary recordings of the Howitzer, Mauser, Stokes, Vickers and Lee Enfield guns made for the purposes of sound design in film and television. These recordings were then grouped and triggered according to who was using them and in patterns that corresponded to archive newsreel footage taken at the front.
