Implementation of an IIR Antiderivative Anti-Aliasing Wavetable Oscillator - Maxime Coutant - ADC 2023
Anti-aliasing is a crucial consideration for digital audio synthesis. Usually, for an oscillator, techniques like band-limited signals or oversampling are employed to mitigate this problem, but I investigated a method a bit more recent : Antiderivative Anti-Aliasing (ADAA). My search for a practical ADAA application in wavetable synthesis first yielded limited results. However, a paper titled "Antiderivative Antialiasing for Arbitrary Waveform Generation," published in August 2022, caught my attention.
The presentation will focus on three aspects:
• An Introduction to ADAA and the algorithm itself
• Insights into practical implementation and results
• Reflections on engaging with Academic Research
By the end of the talk the listener will know about the pros and cons of this technique and how and when to employ it. Furthermore, we will have illustrated some challenges of working with academic material as a software developer.

Maxime Coutant
I'm an audio software engineer in the ADASP group, part of the LTCI public laboratory. Audio enthusiast, hobbyist musician and software addict, I love to share, learn and meet new people! Here at ADC23 I'll present a project I spent many hours on during this last year, hoping to lower the bridge between research and engineering!
