The Side channel is processed as
[ 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 dfx audio enhancer full
Cross‑fading between adjacent bands uses a cosine‑squared window to avoid discontinuities. The exciter applies a non‑linear function f(·) followed by a high‑shelf filter H_s(·) : The exciter applies a non‑linear function f(·) followed
[ y[n] = (1-\gamma) , x[n] + \gamma , H_s\bigl(z[n]\bigr), ] x[n] + \gamma
The gain is applied with a look‑ahead limiter (5 ms) to prevent overshoot. 5.1 Test Materials | Category | Source | Duration (s) | Typical SPL (dBFS) | |----------|--------|--------------|--------------------| | Speech | LibriSpeech test‑clean | 30 | –23 | | Pop | “Uptown Funk” (public domain remix) | 45 | –20 | | Orchestral | Mozart Symphony No. 40 (public domain) | 60 | –25 |
