Source Check · what the input reveals
Signal clues only. This is not a bitrate, codec, or audio-fidelity test. No sound is uploaded.
MASTER LEVEL
Volume booster
Gain is applied before the peak limiter. 600% does not guarantee six times perceived loudness or zero distortion. Start quietly.
Playing tabs
View playing tab titles only with optional Chrome permission. Only one tab can be processed at a time.
Runs only after your click, until the tab is reloaded or leaves this page. Embedded players may be inaccessible.
Local ad diagnostics · for testing
Only counters, relative milliseconds and fixed event types. No video address, title, audio or browsing history. An event cannot prove a real provider ad.
Unmarked sudden loudness is gently limited in Smart and Speech, strongly in Night, and never auto-muted in Music. Only while SoundSavo is on.
How does it work?
Chrome requires you to start processing for each tab. Audio stays on your device. Protected video or some sites may not work. This is not hearing protection.
