Volume Balance 作成者: Adelvo Software

Stop getting screamed at by videos. Broadcast-quality audio leveling for every website.

No more volume chaos! Volume Balance applies real dynamic-range compression to whatever is playing in your browser, so loud passages stop blasting you and quiet passages stay audible.

WHAT IT DOES
• Master volume slider — independent from the compressor
• Real audio compressor with the parameters you'd find in a broadcast plug-in: Threshold, Ratio, Knee, Attack, Release, Makeup Gain
• Built-in presets: Standard, Social Media, Video/Streaming, Night Mode, Gentle
• Save your own custom presets

PRIVACY
• Works entirely in your browser — no audio ever leaves your device
• No analytics, no tracking, no telemetry
• Settings are stored locally via your browser's extension storage
• Full privacy policy: https://adelvo.io/privacy/volume-balance/

PERFECT FOR
Social Media (X, TikTok, Instagram, Reddit), YouTube, podcasts, music sites, lectures, news clips — anywhere video and audio is sometimes too loud and sometimes too quiet.

NOTE
This extension cannot process DRM-protected streams (Netflix, Disney+, Apple TV+, Amazon Prime Video, Spotify Premium, etc.). The browser blocks third-party access to DRM audio for content-protection reasons. For all non-DRM media on the open web, Volume Balance works.

PRICING
$3.99 one-time. Cyclic 10-minute trial without purchase (compression toggles on for 10 min, off for 50, repeating). License is yours forever — no subscription.

Also available as a Safari extension via the App Store (macOS + iOS).
