Chrome routes audio through the browser's output at whatever the operating system provides — no equalization, no correction for your headphones, no adjustment for the content type. A 10-band equalizer changes that. SuperchargeAudio inserts a series of biquad filters in the Web Audio pipeline, one per frequency band, letting you raise or cut specific ranges before the audio hits your ears.

## Frequency Bands

The equalizer covers the full audible range in one-octave steps:

| Band | Frequency | Character |
|------|-----------|-----------|
| 1    | 32 Hz     | Sub-bass, physical rumble |
| 2    | 64 Hz     | Bass weight |
| 3    | 125 Hz    | Upper bass, warmth |
| 4    | 250 Hz    | Low mids, body |
| 5    | 500 Hz    | Midrange, presence |
| 6    | 1 kHz     | Upper midrange, clarity |
| 7    | 2 kHz     | Presence, consonants |
| 8    | 4 kHz     | Bite, articulation |
| 9    | 8 kHz     | Air, high-end sheen |
| 10   | 16 kHz    | Brilliance |

Each band adjusts from −12 dB (strong cut) to +12 dB (strong boost). At 0 dB the band is neutral and transparent.

## Presets

Ten named presets cover common listening scenarios:

| Preset         | Purpose |
|----------------|---------|
| Flat           | All bands at 0 dB — reference/off state |
| Bass Boost     | Strong low-end lift from 32 Hz, tapering through 250 Hz |
| Vocal / Voice  | Presence boost across 250 Hz–4 kHz, with a low cut |
| Treble         | Upper-range lift from the upper mids up |
| Loudness       | Classic smile curve — lows and highs lifted |
| Rock           | Scooped mids, punchy lows, bright highs |
| Pop            | Trimmed lows, forward upper-mid presence |
| Electronic     | Extended sub-bass, airy top end |
| Acoustic       | Balanced natural warmth |
| Small Speakers | Compensates for limited low-end reproduction |

Select a preset as a starting point, then fine-tune individual bands before saving.

## Custom Curves Per Site

Every site you visit can carry its own EQ curve. Dial in settings for a music service, a podcast app, and a video conferencing tool separately — SuperchargeAudio loads the right curve automatically based on the tab's origin.

Combined with [volume boost](/features/volume-boost/), you can normalise both loudness and tonal balance without touching any system-level audio settings.

## Protected Content

On most sites the EQ runs as an in-page Web Audio filter node. For DRM or CSP-locked sites where that is not possible, an opt-in tab-audio-capture mode applies the same EQ to the tab's rendered audio. This is off by default and adjusts only what you already hear — it does not affect content access or DRM protection.

## Privacy

All EQ processing is local. Your saved per-site curves are stored in browser extension storage and never leave your device. No audio data is transmitted; no account is needed.
