## Description

<strong>No more RIP headphone users</strong> extension:

<strong>SleepSafe Sound Audio Normalizer</strong> keeps live streams safe by reducing sudden loud spikes (screams, loud music, TTS, desk slams) <strong>without boosting quiet audio</strong> or changing normal speech. Works on Twitch, YouTube Live, Kick, TikTok Live, Rumble, Trovo, NimoTV, and Bigo.

<strong>Why it helps</strong>
- Prevents ear‑piercing spikes while keeping the stream’s natural mix intact
- No upward normalization: it only turns <em>down</em> extreme peaks

<strong>Key features</strong>
- Peak‑only limiter for spikes and harsh bursts (no overall volume boost)
- Streaming‑only mode + per‑site enable/disable + optional global mode
- Listening profiles for different situations (default, live music, screamers, sensitive ears, loud streams)
- Sleep mode schedule and separate quiet‑hours schedule (mute at your time, restore at wake time)
- Inline on/off + settings next to the player volume on supported sites
- Dashboard with test clips and live analyzer to verify protection

<strong>Privacy</strong>
- No data collection. Settings are stored locally in your browser.
<blockquote>Tip: If a stream has normal speech and stable audio, the limiter stays out of the way.</blockquote>
