Listen to John Chowning tell how he invented FM synthesis
Even more important, the intensity of the higher-frequency spectral components changes as well. And now as its applications on cell phones and cheap PC audio fade cchowning distant memory, FM synthesis is left as one of the great achievements of musical invention, full stop — let alone being a key milestone of 20th century technology. I have to say, it was one of those uniquely inspiring moments, where you get to feel you understand how the sounds you make connect to musical history.
John Chowning’s publication, The Synthesis of Complex Audio Spectra by Means of Frequency Modulation Journal of the Audio Engineering Society, 21 7, describes a basic structure to implement [link] with the following parameters:. In fact, the dynamic nature of the spectra during the instrument’s transient plays an important role in timbre perception.
The [link] screencast video walks through the complete process to implement the Dhowning clarinet instrument in LabVIEW.
Part of that feeling came from the fact that artist Holly Herndon, who herself has studied with John at Stanford, hosted the interview — one sound experimenter and composer to another, student and teacher.
Next post Maschine adds real-time slicing and other stuff you asked for. Chowning was born in Salem, New Jersey in Previous post Love in electronic music, more than ever.
From about thirteen minutes in, you get the story, complete with sound examples. Chowning was also a skilled percussionist. This module refers to LabVIEW, a software development environment that features a graphical programming language. Once the mechanical energy input ceases, the sound concludes by decaying in some fashion to silence.
I thought, well, maybe this is an artifact of the system. December Learn how and when to remove this template message. The prototype waveforms are normalized in both dimensions, i.
Chowning discovered the frequency modulation synthesis FM algorithm in American male classical composers American classical composers Experimental composers births Living people Wittenberg University alumni 20th-century classical composers People from Salem, New Jersey Pupils of Nadia Boulanger 20th-century American composers. Some thought it too expensive at the time, Chowning included. In this way, a louder portion of the note also has more sidebands, because the modulation index effectively controls the bandwidth of the FM spectra.

You can produce even more interesting sounds with a time-varying modulation index to alter the effective bandwidth and sideband amplitudes over time. Algorithmic composition Sound synthesis. From Wikipedia, the free encyclopedia. Please help improve this article by adding citations to reliable sources. Chowning is known for having discovered the FM synthesis algorithm in Johnstone ; Schottstaedt ; Chowning This breakthrough in the synthesis of timbres allowed a very simple yet elegant way of creating and controlling time-varying spectra.
Inspired by the perceptual research of Jean-Claude Risset, he worked toward turning this discovery into a system of musical importance, using it extensively in his compositions. Physical musical instruments produce audio spectra that evolve with time. In essence, the amplitude and frequency of one waveform modulates the frequency of another waveform producing a resultant waveform that can be periodic or non-periodic depending upon the ratio of the two frequencies.
The high-frequency components are often more evident during the initial transient. Following military service and four years at Wittenberg University, he studied composition in Paris with Nadia Boulanger.
The sound continues with some type of quasi steady-state behavior when mechanical energy is continually applied, chowniny. He taught computer-sound synthesis and composition at Stanford University’s Department of Music.
