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 dfx audio enhancer full

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 [ G_b[n] = 1 - \frac11 + \left(\frac\lVert

[ 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
