Method adjustRateToFPS

src/fl/audio/detector/vibe.cpp.hpp:196–203

FPS-independent rate adjustment: Converts a per-frame smoothing rate tuned at fps1 to the equivalent rate at actualFps, preserving the per-second behavior. At 30fps with rate=0.5: per-second retention = 0.5^30 ≈ 9.3e-10 At 60fps the per-frame rate adjusts to ~0.707 so 0.707^60 ≈ 9.3e-10 (same)

// At 30fps with rate=0.5: per-second retention = 0.5^30 ≈ 9.3e-10
// At 60fps the per-frame rate adjusts to ~0.707 so 0.707^60 ≈ 9.3e-10 (same)
