Gordon Reid embarks on a journey to synthesize convincing woodwind and brass. This month, he considers how these instruments make their sounds in real life.
Ever heard a synth talk? If you have, it's due to formant synthesis. Gordon Reid explores the theory of analogue formant synthesis, how it relates to the human voice and modern digital synths like Yamaha's FS1R.
Last month, we examined the frankly scary maths allowing you to predict the audible effects of Frequency Modulation. This time, although the maths gets even tougher, Gordon Reid relates the theory to the practical implementation of FM synthesis on Yamaha's digital synths, as well as modular and non-modular analogues.
As explained last month, audio-frequency modulation of the amplitude of a signal can be a powerful synthesis tool. The possibilities expand still further when we consider what happens when you use one audio-frequency signal to modulate the frequency of another...
Last time, we examined the concept of modulation at low frequencies. This month, we speed things up a bit. The result is not just faster versions of the same modulation effects, but a new type of synthesis...
