Build Your Own Synthesiser

Sebastian Beswick, Art Processors Part of DW18

Algorithmic sound is a fascinating field! It’s ubiquitous in everyday life, but not many people understand how it works. It’s actually quite simple, and the lightswitch moment of understanding something that you previously took to be black magic is glorious.

This talk focuses primarily on computer sound representation and synthesis, which is relatively simple to implement regardless of language. As such, this talk will be suitable for attendees of all levels of iOS experience. In this session we’ll go back to basics and take a look at the core components of sound, including how we perceive sounds, and how we can represent them within a computer. We’ll go on to look at the theory behind the CoreAudio Framework, and finish up with a live demo, where we use audio units to create our own simple synthesiser.
