This month Haskell will present "The Synthesis of Complex Audio Spectra by Means of Frequency Modulation" by J.M. Chowning. Originally published in 1973 by the Journal of the Audio Engineering Society, this paper describes a method of sound synthesis referred to as FM synthesis that can be used to create interesting timbres of sound by modulating an audible carrier wave with another high frequency wave or a series of these waves. This is rather much of an oversimplification and there's a fair amount of jargon and abstraction that has grown up around these ideas.
FM Synthesis has been fairly popular lately amongst music instrument manufacturers and musicians, but it has a long history and was also the primary method of synthesizing sounds in many older computer games and a lot of specialized hardware used to exist for just this purpose.
Come join us to talk about this paper and FM synthesis- it's pretty rad. Food will be provided.
