Godot Audio Systems

This is a comprehensive reference for Godot's audio engine that covers the stuff most tutorials skip. It handles bus routing and logarithmic volume correctly, includes pooling patterns to avoid spawning hundreds of AudioStreamPlayer nodes per second, and ships with actual scripts for occlusion raycasting, voice limiting, and vertical music layering. The "never do" rules are solid: they cover common mistakes like forgetting attenuation models on 3D players or using linear values for bus volume. Use this when you're building a real audio system and need patterns for crossfades, spatial audio, or dynamic mixing instead of just playing a one-shot sound effect.
