LLM interactive narrative

An interactive audiobook in Unreal Engine 5: a choose-your-own-adventure built on a novel. The book plays as written in cloned character voices, then pauses for the player. Go off-script and a local LLM improvises in character, grounded by a RAG search over what you’ve heard so far. Fully self-hosted on one GPU.

About

I’ve been hooked on sound since I was 13, the first time I heard Dolby Pro Logic surround in a family friend’s home theater.

Years later I was hand-building crude 5.1 mixes in Cakewalk for my family’s Halloween haunted house, and in 2004 that obsession took me to Vancouver Film School’s Sound Design program.

Twenty years on, I’ve worked across the whole pipeline: audio QA and Audio Artist at EA Canada on Need for Speed, Medal of Honor, Army of Two and Skate; dialogue editing for Relic; senior audio designer at Hothead; and since 2022 Offworld Industries, where I went from Technical Audio Designer to Audio Director on Squad and Starship Troopers: Extermination.

Mixing is where I’m happiest: bringing every element together into one soundscape of emotion. Outside work you’ll find me writing, watching horror movies, or chasing a sound I heard in a film with a new plug-in.
