sl-jetson	e8b787a987	feat(social): speech volume auto-adjuster — Issue #289 Some checks failed social-bot integration tests / Lint (flake8 + pep257) (push) Failing after 9s Details social-bot integration tests / Core integration tests (mock sensors, no GPU) (push) Has been skipped Details social-bot integration tests / Lint (flake8 + pep257) (pull_request) Failing after 8s Details social-bot integration tests / Core integration tests (mock sensors, no GPU) (pull_request) Has been skipped Details social-bot integration tests / Latency profiling (GPU, Orin) (push) Has been cancelled Details social-bot integration tests / Latency profiling (GPU, Orin) (pull_request) Has been cancelled Details Adds volume_adjust_node to saltybot_social: - Subscribes /social/speech/energy (Float32 linear RMS [0..1] from vad_node) - Maps energy to TTS volume via: 1. Normalise into [noise_floor, noise_ceil] 2. Power-curve shaping (curve_gamma; <1 concave, 1 linear, >1 convex) 3. Lerp to [min_volume, max_volume] 4. Exponential moving-average smoothing (smoothing_alpha) - Publishes Float32 on /saltybot/tts_volume at publish_rate Hz (default 5 Hz) - Holds last value when energy is stale (> stale_timeout_s) - All params exposed: min/max_volume, noise_floor/ceil, curve_gamma, smoothing_alpha, publish_rate, stale_timeout_s - 74/74 tests passing Closes #289	2026-03-02 20:47:53 -05:00
