Electrical Reproduction of Acoustically Recorded Cylinders and Disks
This paper will discuss the audio restoration and electrical recording of the Napleson cylinders from the 1901, 1902, and 1903 Metropolitan Opera seasons. Original Edison blanks were shaved and recorded (under controlled conditions) with pink noise, tone sweeps, digital-generated-frequency-source signal, and simultaneous recording, acoustically and electrically, of a wind ensemble. Acoustical analysis, groove analysis, wax formulation, surface-to-noise content, and horn-resonance frequencies were sampled and plotted. Slides and musical examples verify the results achieved.
