about

the ninth synthesis techniques challenge - In this weekly series we'll explore the myriad of ways one can synthesize sound.
This week, we're doing more maths stuff with additive synthesis! Despite what you may have heard, additive synthesis has precisely one definition: the summation of elementary waveforms to create more complex waveforms. In modern use, this is achieved through sine waves, however it's been a thing for centuries in the form of pipe organs, which are very much non-sinusoid generators. Now, before you go about just mixing any waves together willy nilly and saying it's additive synthesis, we're specifically going to employ harmonic addition, which means setting individual harmonics to varying levels to create the sounds we want. Harmonics are integer multiples of the fundamental, so if you have a 100Hz base frequency, the harmonics would be 200, 300, 400, etc. Technically speaking, most additive synths will employ partials, which are non-integer multiples and thus allow for inharmonic partials as well as harmonic partials. This is how you get truly powerful waves from additive synthesis, and is why so many additive synths employ macros: there's just too many parameters! So, for this week, I want you to find yourself some sine waves, or an additive synth (mode 5 green on plaits works) and create yourself some neat waveforms! Normally I limit extra stuff to light effects and open modulation, but this time I actually encourage the use of wavefolders, after you've got the concept of additive. It really opens a wide world for you to explore. Have fun, and I'll have a new one next Friday!
