- Add configurable constants to detect hot inputs: la2aHotInputTPThreshold, la2aHotInputTPSevere, la2aHotInputRatioReduction, la2aHotInputHeadroomReduction - Back off LA-2A ratio when measured true peak exceeds the threshold. Use a square-root scaled severity to apply a smooth, non-linear reduction up to the configured maximum. - Reduce LA-2A headroom (raise threshold) for loud inputs using the same severity curve so the compressor applies gentler gain reduction. - Rationale: the downstream limiter handles peak control; backing off the compressor for already-hot material avoids unnecessary dynamics crushing and preserves perceived dynamics. IMPACT: gentler compression on files with high true peaks; reduces over-compression without changing limiter behaviour. No breaking changes. Signed-off-by: Martin Wimpress <martin@wimpress.org>
