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 | x[n] + \gamma
