Features
Only what you need, nothing you don't
Built for people who care about their audio quality — whether it's a podcast, a movie, or a YouTube video with a bad mix.
🎚
8-Band Parametric EQ
Full-range control from 32 Hz to 8 kHz. Each band adjustable ±12 dB with precise per-slider control. Flat by default — only shape what needs shaping.
🎙
Voice Enhancer
Four curated presets — Off, Dialogue, Leveler, and Clarity — each tuned for a different listening scenario. Leveler includes a dynamics compressor ( DSP ).
📊
Live FFT Visualizer
Real-time spectrum display driven by the post-processing audio signal, so you see exactly what you're hearing after the EQ curve is applied.
🔒
100% Local Processing
All audio processing happens inside your browser using the Web Audio API. No audio data ever leaves your device. No servers, no accounts, no tracking.
💾
Persistent Settings
Your EQ curve, knob positions, and Voice Enhancer mode are saved automatically. Open the extension a week later and your settings are exactly where you left them.
⚡
Low-Latency Routing
Tab capture runs in an offscreen document separate from your page, so the extension never touches the page DOM and doesn't slow down the site you're on.
Voice Enhancer
Four modes for every source
Pre-tuned curves that fix common audio problems in one click. Switch modes without stopping playback.
Off
Bypass
Voice Enhancer inactive. Your manual EQ curve and gain settings still apply. Use this when you want full manual control.
Dialogue
Speech clarity
Cuts low mud, boosts upper-mid presence. Designed for podcasts and videos where voice sits too far back in the mix.
Leveler
Speech Leveler
Adds a dynamics compressor to even out loud and quiet passages. Ideal for content with inconsistent levels, like live recordings.
Clarity
Air & Detail
Progressive high-frequency lift that opens up the sound. Works well on compressed streaming audio that sounds dull or closed-in.
