Recent advances in Wax recording

This paper considers chiefly the frequency-response characteristics and limitations of the lateral cut “wax” record. It shows that the frequency range from 30 to 8,000 cycles can be recorded and reproduced from the record with practically negligible deviation from a flat frequency-response characteristic. The paper brings out the ease with which the record can immediately be replayed from the “wax” as an aid in assisting the artist to obtain the best results. A brief description is given of commercial processing methods including both plating and pressing. These methods give essentially a perfect copy of the original “wax.” The time required far this work has been considerably reduced of late so that a test pressing can be obtained within three hours of the cutting of the original “wax.”
