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 Let L[n] and R[n] denote left/right channels

[ 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

[ G_\mathrmLU = 10^(L_\mathrmtarget - L_\mathrmint)/20. ] The target loudness L_target (default = –14 LUFS)
