PannerNode + occlusion biquad wrapper. Inserted between a Voice and
its Bus when a play call passes a 
`spatializer`
 option.

- 2D pan uses 
`StereoPannerNode`
 (cheap, just left/right shift).
- 3D uses 
`PannerNode`
 in HRTF mode (one node per voice — fine for
  the dozens of simultaneous voices a typical game holds, expensive
  past hundreds), followed by a biquad lowpass for occlusion plus a
  gain stage so occlusion can also drop level slightly.

3D config (
`refDistance`
, 
`maxDistance`
, 
`rolloffFactor`
,

`distanceModel`
) is configurable per voice via 
`SpatialOptions`
 and
tunable live via the 
`set*`
 methods. Occlusion is a single 0..1 knob
that drives the lowpass cutoff plus a small gain dip.

# Spatializer

PannerNode + occlusion biquad wrapper. Inserted between a Voice and its Bus when a play call passes a \`spatializer\` option. - 2D pan uses \`StereoPannerNode\` (cheap, just left/right shift). - 3D uses \`PannerNode\` in HRTF mode (one node per voice — fine for the dozens of simultaneous voices a typical game holds, expensive past hundreds), followed by a biquad lowpass for occlusion plus a gain stage so occlusion can also drop level slightly. 3D config ( \`refDistance\` , \`maxDistance\` , \`rolloffFactor\` , \`distanceModel\` ) is configurable per voice via \`SpatialOptions\` and tunable live via the \`set\*\` methods. Occlusion is a single 0..1 knob that drives the lowpass cutoff plus a small gain dip.
