Pro-grade audio in your browser
Volume boost, noise reduction, 10-band EQ, per-tab mixing, stereo widening, and practical audio presets — all running in your browser.
Volume Boost up to 800%
Laptop speakers too quiet? Boost supported tab audio from 0% to 800% with a single slider. Hearably's look-ahead limiter reduces digital clipping, while the final result still depends on the source audio and your speakers or headphones.
- Gain range: 0x to 8x (0%–800%)
- Look-ahead peak limiting at high gain
- Brick-wall limiter at -0.3 dBFS
- 20ms parameter ramping to reduce clicks
10-Band Parametric EQ
Full control over your frequency spectrum. Each of the 10 bands (31Hz to 16kHz) offers ±12dB of gain with adjustable Q factor. Shape your audio like a pro — cut rumble, boost vocals, add sparkle.
- Bands: 31, 62, 125, 250, 500, 1K, 2K, 4K, 8K, 16K Hz
- ±12dB range per band
- Real-time visual frequency response
- Save custom EQ curves as presets
Per-Tab Audio Mixer
Every tab with audio gets its own channel strip. Adjust volume independently, mute specific tabs, apply different presets to different tabs. Like a mixing console for your browser.
- Independent volume per tab
- Mute/solo per channel
- Different presets per tab
- Real-time level meters
Keyboard Shortcuts
Control the most common actions without interrupting the video, call, or music you are listening to. Shortcuts are managed by Chrome and can be changed from the browser's extension shortcut settings.
- Open the Hearably panel with Alt+S
- Toggle enhancement with Alt+E
- Raise or lower gain with Alt+Up / Alt+Down
- Customize shortcuts in Chrome or Edge
Noise Reduction
An adaptive noise gate with RMS envelope detection that removes background hiss, fan noise, and keyboard clicks in real time. Soft gating ensures natural-sounding transitions — no abrupt cuts or artifacts.
- Adaptive threshold based on ambient noise floor
- Soft gate with smooth attack/release
- Works with video calls, streams, and podcasts
- Zero-allocation real-time AudioWorklet
Night Mode
Dynamic range compression that keeps dialogue clear while taming loud explosions, music stings, and sudden sound effects. Perfect for late-night watching when you don't want to wake anyone.
- Heavy compression ratio for quiet listening
- Bass reduction to avoid wall vibrations
- Dialogue stays clear and present
- One-click toggle from the main panel
Ad Volume Guard
Detects sudden volume spikes — like when an ad blasts at twice the volume of the video — and clamps them instantly. Uses a rolling RMS average to detect spikes greater than 6dB and applies smooth gain reduction.
- Auto-detects volume spikes over 6dB
- Smooth gain clamping (no artifacts)
- 200ms hold period for natural release
- Works alongside volume boost and EQ
Voice Boost
Targeted amplification of the 1–4kHz speech presence range. Makes dialogue, vocals, and speech cut through background music and effects on video calls, podcasts, and streaming platforms.
- Focused 1–4kHz presence enhancement
- Improves speech intelligibility
- Works great with Netflix, Zoom, and podcasts
- Combines with Night Mode for ultimate clarity
Stereo Widener
Mid/Side encoding expands or narrows your stereo field from 0% (mono) to 200% (extra-wide). Makes music feel more immersive on headphones, or tightens vocals for speech clarity.
- 0% (mono) to 200% (wide) stereo width
- Mid/Side encoding preserves center content
- Per-preset stereo width settings
- Great for music, gaming, and film
