A Critique of Audio Plug-In Formats - VST, AU, AAX, JUCE and Beyond - Fabian Renn-Giles - ADC 2024
---

Audio plug-in formats such as VST, AU, and AAX have revolutionized the audio workflow, empowering a whole industry of creative coders. However, as programming paradigms and user expectations evolve, the design decisions of these established formats must be re-evaluated. This talk critically examines these design choices, exploring how they can be improved, and there is a new contender: CLAP.

The presentation is divided into two sections: a developer-focused critique and a customer-centric analysis. The developer-focused section delves into fundamental design flaws in plug-in APIs, such as stateful lifecycle management, poor single-use interface design, and why the overarching synchronous “process block” design may become quickly outdated with ever-increasing specialized hardware. The talk also discusses more audio plug-in specific issues like ambiguous parameter/state ownership, the limited utility of the “maxSamplesPerBlock” parameter, and what we can learn from Linux about negotiating bus formats.

The second section critiques audio plug-ins from the user’s standpoint. The talk explores major pain points such as lack of portability, cumbersome copy-protection mechanisms, and the archaic practice of plug-in scanning. The section concludes with a call-to-action for the industry to adopt unified standards as the only real solution to these problems.
