Summary: John Chowning pioneered frequency modulation (FM) synthesis in the 1970s, and demonstrated how the technique could simulate a diversity of instruments such as brass, woodwinds, and percussion. FM synthesis produces rich spectra from only two sinusoidal oscillators, and more interesting sounds can be produced by using a time-varying modulation index to alter the effective bandwidth and sideband amplitudes over time. A LabVIEW VI is developed to implement the sound of a clarinet, and the VI can be easily modified to simulate the sounds of many other instruments.
