🎛️ POWERFUL FEATURES

🔈 Volume Amplification (0% – 500%)
Drag the slider to boost any tab's audio up to 5x the normal volume. Our non-linear gain curve ensures smooth, natural amplification — no harsh clipping or sudden jumps.

🎵 Bass & Treble EQ Controls
Adjust bass (-10 to +10 dB) and treble (-10 to +10 dB) independently. Whether you want thumping bass for music or crystal-clear highs for speech — you're in control.

🎧 4 Smart Presets
One-click audio profiles tailored for different content:
• General — balanced, everyday browsing
• Speech — enhanced clarity for podcasts, lectures, and video calls
• Music — boosted bass and bright treble for songs and playlists
• Movie — deep bass with warm mids for cinematic sound

📊 Real-Time Visualizer
A live frequency visualizer in the popup shows your audio activity in real time. It's not just functional — it looks cool too.

🛡️ Distortion-Free Boost
Our built-in brick-wall limiter and dynamics compressor work together to catch audio peaks before they clip. The result? Louder audio without the ugly distortion that other boosters produce.
