Pro-grade audio in your browser
Volume boost, live captions, noise reduction, 10-band EQ, per-tab mixing, stereo widening, and AI-powered content tools — all running in your browser.
Volume Boost up to 800%
Laptop speakers too quiet? Boost any tab's audio from 0% to 800% with a single slider. Hearably's distortion guard uses a soft-knee limiter that progressively engages above 400%, keeping your audio clean at any volume.
- Gain range: 0x to 8x (0%–800%)
- Soft-knee distortion guard above 400%
- Brick-wall limiter at -0.3 dBFS
- 20ms parameter ramping (zero 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
Live AI Captions
Real-time speech-to-text on any website. Hearably runs Whisper AI entirely in your browser — no cloud, no data leaves your device. A subtitle overlay appears on the page as audio plays, with automatic language detection.
- 90+ languages with auto-detection
- In-page subtitle overlay (draggable)
- Voice Activity Detection gates inference
- Works on YouTube, Netflix, Zoom, and any website
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
