Steady Volume: 音量ブースター＆音量平準化 作成者: olerast

Steady Volume is a volume booster and loudness leveler for video and audio on websites. It raises quiet dialog in films and series, lowers explosions and loud music, and keeps the boosted sound from distorting with a limiter.

How to use: install, play a video. Auto mode is on by default, nothing needs setting up.

Settings:
- Volume boost from 100% to 600%.
- Leveling modes: Off, Light (music), Auto (films, series, YouTube), Night (quiet watching at night).
- Clearer speech: less low rumble, more voice presence.
- Fine-tuning for those who want it: target loudness, compressor threshold and ratio, limiter ceiling, gain recovery time.
- A switch to turn the extension off on a particular site.

Works with <video> and <audio> players on any site, including YouTube, HLS and DASH players, embedded players from other domains and players built as web components. When a video can't be connected directly, for example DRM-protected streaming, the extension processes the sound of the whole tab (open the popup or press Alt+Shift+V). Calls and voice chats are left untouched.
