Boost video audio volume up to 1000% with real-time gain control # VoiceBoost VoiceBoost is a lightweight Chrome extension that lets you amplify the volume of videos and audio beyond your device's default limit. Whether you're watching online lectures, listening to podcasts, streaming media, attending online meetings, or enjoying music, VoiceBoost helps make quiet audio louder and clearer with real-time sound amplification. Unlike your browser's built-in volume controls, VoiceBoost processes audio directly in the browser using the Web Audio API, allowing you to increase volume by up to **1000%** while maintaining low latency and smooth playback. ## Features * 🔊 Boost audio volume from **100% up to 1000%** * 🎵 Works with most websites that use standard HTML5 audio and video * ⚡ Real-time audio processing with minimal delay * 🎧 Ideal for videos, podcasts, online courses, meetings, and music * 🎚️ Simple and easy-to-use volume slider * 💻 Lightweight and optimized for performance * 🔒 No account required * 🚫 No ads or unnecessary tracking * 🌙 Clean and intuitive interface ## Compatibility VoiceBoost is designed to work with most websites that use standard HTML5 audio or video playback. Compatibility depends on how each website delivers media. Some DRM-protected or encrypted content may have browser-imposed limitations that prevent audio amplification. ## How It Works VoiceBoost uses the browser's Web Audio API to create a gain node that amplifies audio before it reaches your speakers or headphones. Audio is processed entirely within your browser and never uploaded or recorded. ## Privacy Your privacy is important. VoiceBoost: * Does **not** collect personal information. * Does **not** record or store audio. * Does **not** transmit your browsing data. * Does **not** require an account or sign in. * Processes audio entirely on your local device. ## Permissions VoiceBoost requests only the permissions required to: * Detect audio and video elements on webpages. * Apply real-time audio amplification. * Save your preferred volume settings locally. No unnecessary permissions are requested. ## Notes Very high amplification levels may introduce distortion depending on the original audio quality and your audio hardware. For the best listening experience, increase the volume gradually. ## Why Choose VoiceBoost? Whether you're watching a quiet documentary, attending an online class, listening to a soft-spoken podcast, or joining a video meeting with low audio, VoiceBoost provides an easy way to increase volume directly in Chrome without installing additional software or changing your operating system settings.
