3D Audio in Games: What, Where, Why and How?
summary
Clear, actionable claims: a bottom-up explanation of 3D audio from HRTFs to implementation, concrete measurement and rendering steps, and practical PS5 best practices including the PS5 five presets for headphone personalization. Compares real methods with tradeoffs — ambisonic vs object workflows — and flags real pitfalls like cone-filtering from virtual loudspeakers. Includes tooling and test routes (Reaper, VSTs, ambisonic orders) so viewers learn how to measure, render, and deploy 3D audio now.
