AudioGraphLimiter
Brick-wall look-ahead limiter (linked channels). Content is delayed by the look-ahead (reported as latency; PTS preserved). lookahead_ms is fixed at build; ceiling_db / attack_ms / release_ms are runtime params. With true_peak the detector is 4x oversampled inter-sample peaks (BS.1770), so the ceiling can be a true-peak (dBTP) limit directly; without it the detector is sample-peak — allow ~1 dB inter-sample margin on the ceiling.
