FoxSound — Music, Crossfade & Region Audio Toolkit

A production-ready audio toolkit for Blueprint projects. Crossfade music tracks, fade volume by tag, chain stingers, follow actors with looped SFX, and drive a complete region-based music system — combat, danger, peaceful — without building a custom audio subsystem.
