Interface and Render Scheduler Design for Neural Audio Synthesizers: Part 1
We examine a new paradigm of virtual instruments based on locally-run deep neural networks, and discuss its implications on overall interface design. "Interface" carries multiple meanings here—the UI-engine interface, the user interface, and the host-plugin interface—all of which must be considered in tandem to deliver a smooth user experience.
Part 1 of this talk focuses on defining and analyzing the core problems. We introduce multi-stage rendering pipelines, caching strategies, and resource prioritization techniques designed to ensure responsiveness in heavy audio editing workflows.
