Musical Timbre Mutation by Means of the -Klangumwandler," a Frequency Transposition Device
A uniform shift in the frequency of all the harmonics in any sound can be achieved by a device named -Klangumwandler-, which was developed for this purpose by Dr. L. Heck and Mr. F. Burek of the Southwest German Radio. This shift affects frequency ratios among the harmonics with the resultant radical changes in timbre. The main features of this device are described; a sound demonstration of the results obtained by the author will suggest certain possible applications in the field of music and acoustics.
