where T_b is the band‑specific threshold and α_b controls the knee curvature. The RMS detector uses a 50 ms smoothing window. The final output for band b is [ M[n] = \fracL[n] + R[n]2,\qquad S[n] = \fracL[n] - R[n]2

with β controlling drive (0 ≤ β ≤ 5) and γ the blend factor (0 ≤ γ ≤ 1). The high‑shelf has a cutoff at 4 kHz and a gain of up to +6 dB. Let L[n] and R[n] denote left/right channels. The Mid (M) and Side (S) components are The final output for band b is with

[ L'[n] = M[n] + S'[n],\qquad R'[n] = M[n] - S'[n]. ] A perceptual loudness model based on the ITU‑R BS.1770‑4 algorithm computes the integrated loudness L_int over a 400 ms window. The target loudness L_target (default = –14 LUFS) determines a gain factor

[ y_b[n] = G_b[n] \cdot x_b[n]. ]

Statistical analysis (ANOVA, p < 0.01) confirms that DFX‑AE (default) yields a significant improvement over the original and the competitor across all categories.
