Reiss Panning

Two stereo-pan algorithms selectable at runtime:

• Panorama + Precedence - tangent-law gain combined with a per-side time delay derived from the pan position. Aimed at loudspeakers.
• ITD + ILD - spherical-head model producing an interaural time difference (via fractional delay) and an interaural level difference (via a first-order shelf). Aimed at headphones.

#What it demonstrates

• Two pan implementations sharing the same parameter surface, selected by EnumParam
• Per-channel short delay lines for the time-difference half
• A simple shelf filter for the level-difference half
