Features & Capabilities

No more RIP headphone users extension:

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

Why it helps

  • Prevents ear‑piercing spikes while keeping the stream’s natural mix intact
  • No upward normalization: it only turns down extreme peaks

Key features

  • 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

Privacy

  • No data collection. Settings are stored locally in your browser.
Tip: If a stream has normal speech and stable audio, the limiter stays out of the way.

Is SleepSafe Sound Audio Normalizer Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SleepSafe Sound Audio Normalizer requires a lot of sensitive permissions. Exercise caution before installing.
