ボリュームブースター 作成者: Volume Booster

Tired of one global volume slider? Volume booster gives every browser tab its own level: push any tab up to 500% louder, or mute just that tab—without touching the rest of your audio. Perfect when YouTube is barely audible but your call still needs to be clear, or when you want one stream loud and another silent.

What you get: independent boost up to 500% and per-tab mute, a 10-band equalizer to shape bass, mids, and treble, and support for video, music, podcasts, live streams, and calls. Multitasking stays clean—you only adjust the tab that’s actually playing.

Install once and keep sound control where it belongs: on the tab that’s making the noise.
