When outputAttack > 0 AND outputDecay > 0, uses AttackDecayFilter instead of ExponentialSmoother for per-bin output smoothing. WLED-MM uses attack ~24-50ms, decay ~250-300ms. Output attack time (seconds). 0 = use smoothing tau.

float outputDecay = 0.0f Output decay time (seconds). 0 = use smoothing tau. FFTScalingMode scalingMode = FFTScalingMode::None FFT bin scaling mode applied to raw magnitudes before normalization. float silenceThreshold = 10.0f Raw RMS threshold for silence detection. float smoothing = 0.05f Bin temporal smoothing (ExponentialSmoother tau, used as attack)
