Chrome’s volume slider stops at 100%. SuperchargeAudio removes it by inserting a Web Audio gain node on the tab’s audio pipeline, letting you push output up to 600% of the original signal. For quiet podcasts recorded at low levels, old archival video, or video calls where the other person’s microphone is too soft, that ceiling is a real constraint.

How Volume Boost Works

Web Audio API exposes a GainNode — a processing stage that multiplies the amplitude of an audio signal by a fixed factor. SuperchargeAudio creates one per tab and places it between the page’s audio context and the output. A gain of 1.0 is unity (no change); 6.0 produces a signal six times the original amplitude.

The result is instant. Dragging the slider to 200% doubles the signal gain; 400% quadruples it.

Gain Levels

The slider runs in 70 detents from 0% to 600%: fine 1% steps from 0% to 9%, then 10% steps up to 600%. These are reference points; for most quiet content, 150–250% is enough.

When to Use Volume Boost

• Podcasts or lectures recorded at low levels
• Video calls where the other participant’s audio is persistently soft
• Archival or historical video content
• Any site where Chrome’s system volume at 100% is still too quiet

For already-loud content, leave the slider at 100% and use the equalizer to shape frequency response instead.

Protected Content

Standard volume boost works via an in-page gain node and needs no special permissions. On DRM-protected streaming sites, or any site whose audio the in-page path can’t reach — a cross-origin file or a player inside an embedded frame — SuperchargeAudio provides an optional Protected boost. This captures the tab’s rendered audio output — the audio you already have access to — and applies the same gain controls.

To be clear on what this does not do: it does not decrypt content, bypass access controls, or enable anything you could not already hear. It is opt-in and off by default.

Privacy

All audio processing happens inside Chrome on your device. No audio data, volume settings, or site information is transmitted. SuperchargeAudio has no server component for this feature, no account requirement, and no analytics.
