The “Selenophon” Sound Recording and Reproducing System

G. E. Roth

This paper provides further details of the Selenophon system described previously in the Journal, and an account of recent developments of the system. Records can be made by either the variable-width or the variable-density method; the latter being used almost exclusively for film recording, aud the former for recording on paper. The paper records were produced in order to provide a means of recording sound in the home and for other “stenographic” purposes at small cost.
