Adaptive Radio System Using MetaSounds for Serious VR Game

ABOUT

This journal article is about building an adaptive in-game radio for VR that reacts to player context using Unreal Engine's MetaSounds and a finite-state machine. Instead of fixed playlists, the system switches between three affective music states: Happy, Excited, and Intense with smooth crossfades, loudness balancing, and optional beat-synced transitions. Tested with 30 VR users, the approach was rated intuitive and more immersive than non-adaptive audio, suggesting that this engine-native MetaSounds–FSM method can meaningfully enhance engagement in serious VR experiences.
