MixerParameters

Remarks

What a snapshot is not. MixerSnapshots blends to a named state over a duration — discrete destinations, arrived at. This is a continuous dial: rain = 0.4 is a real mix and so is 0.41. Where a snapshot says "the underwater mix", a parameter says "this much underwater", and the difference is whether the transition is a thing that happens or a thing that is being held at a position.

And what a per-voice parameter is not. Everything here is shared by everything routed through it, so it cannot say "this player is underwater and that one is not". That is AudioParameterSheet, attached per sound. The two are deliberately separate types rather than one with a scope flag, because the set of things each can drive has no overlap at all.

Resolved once, applied every frame. Names become bus, send and effect references at construction, and anything that does not resolve is reported rather than thrown — a mixer is content. After that a step is arithmetic and a handful of property writes.
