Volume Booster & Video Speed Controller - Bass Boost

About

Volume Booster & Video Speed Controller is the all-in-one audio amplifier and playback speed tool for Chrome. Boost any tab's volume up to 600% using real DSP audio processing, fine-tune sound with a built-in bass boost and voice enhancement equalizer, and control HTML5 video playback speed — all from a single, lightweight extension.

Works on every website with audio or video, including YouTube, Netflix, Amazon Prime Video, and more.

Unlike simple volume sliders, this extension uses a professional-grade Web Audio engine with a dedicated gain stage, low-shelf bass filter, and peaking voice-clarity filter. The result: louder audio that actually sounds clear, not distorted.


★ VOLUME BOOSTER — LOUDER, CLEARER SOUND

• Boost tab volume up to 600% beyond your system maximum
• Real-time gain control with a smooth, responsive slider
• Perfect for laptops with weak speakers, quiet videos, low-volume streams, and online meetings
• Sound amplifier that increases audio levels far beyond what your system volume allows


★ BASS BOOST & VOICE ENHANCEMENT EQUALIZER

• Built-in low-shelf bass filter to add deep, rich bass to music and movies
• Voice-clarity peaking filter to make dialogue, lectures, and podcasts easier to hear
• Adjust bass and voice enhancement levels independently
• Audio equalizer with real DSP processing — not just a simple volume slider
• Sounds clear even at high volume levels — no clipping, no crackling


★ VIDEO SPEED CONTROLLER — PLAYBACK SPEED FOR ANY VIDEO

• Speed up or slow down any HTML5 video on any website
• Adjustable from 0.25x slow motion to 4x fast playback
• On-screen speed indicator so you always know the current playback rate
• Shadow DOM overlay — the speed display never breaks the page layout
• Change video speed with keyboard shortcuts or the popup panel


★ PER-SITE MEMORY — SET IT AND FORGET IT

• Remembers your preferred volume and speed settings for each website
• YouTube at 2x speed, lecture sites at 1.5x, a quiet streaming service boosted to 300% — all saved automatically
• Settings persist across sessions and after browser restarts
• No need to re-adjust anything when you return to a site


★ KEYBOARD SHORTCUTS FOR POWER USERS

• Ctrl+Shift+Up / Down — increase or decrease volume by 10%
• Ctrl+Shift+Period / Comma — speed up or slow down video playback

★ LIGHTWEIGHT, PRIVATE & SECURE

• No data collection, no analytics, no ads, no tracking
• All audio processing happens locally in your browser using the Web Audio API
• Minimal permissions: only storage (to save your preferences), activeTab, and tabs
• No remote code execution — everything runs on your device
• Open and transparent: clear permission justifications, no hidden access


★ WHO IS THIS EXTENSION FOR?

• Students and online learners who watch lectures and courses at faster speeds to save time
• Movie and TV fans who need louder audio from streaming services on laptop speakers
• Podcast listeners who want to speed through episodes or boost quiet recordings
• Gamers who need to amplify in-browser game or stream audio

• Anyone with a laptop or computer with speakers that just aren't loud enough


★ HOW IT WORKS

1. Install from the Chrome Web Store — it takes just one click
2. Click the extension icon in your toolbar to open the control panel
3. Slide the volume booster to amplify sound up to 600%
4. Toggle bass boost or voice enhancement for richer, clearer audio
5. Adjust video playback speed with the speed controller
6. Your settings are automatically remembered for each website

Audio is processed using a professional Web Audio API graph: a gain node for volume amplification, a low-shelf filter for bass enhancement, and a peaking filter for voice clarity. This DSP pipeline is the same approach used in professional audio software — applied directly in your browser, in real time.


★ WHY CHOOSE THIS EXTENSION OVER OTHERS?

Most Chrome extensions are either a volume booster OR a video speed controller. This extension combines both into one tool — saving you toolbar space, memory, and the hassle of managing multiple extensions.

Unlike basic volume boosters that simply raise the gain (and produce distortion), this tool uses a full Web Audio engine with bass boost and voice filters, so your audio stays clean and natural even at 400–600% amplification.

Also built on Manifest V3 with minimal permissions and zero data collection. Your privacy is fully respected — no accounts, no sign-ups, no telemetry.


★ FREQUENTLY ASKED QUESTIONS

Q: Will boosting volume above 100% damage my speakers?
A: This extension uses digital amplification, which increases the audio signal inside the browser. Use moderate levels (200–400%) for the best balance of volume and clarity. Very high levels on already-loud content may cause distortion, but this will not damage hardware.

Q: Does it work on Netflix, Disney+, and other streaming services?
A: Yes. This extension works on any website that plays audio or HTML5 video, including all major streaming platforms.

Q: Can I speed up YouTube videos beyond 2x?
A: Yes. While YouTube's built-in speed control stops at 2x, this video speed controller lets you go up to 4x playback speed on any HTML5 video.

Q: Does this extension collect any data?
A: No. This extension does not collect, store, or transmit any personal data. All audio processing is 100% local on your device.

Q: Is it free?
A: Yes. Completely free to use with no premium tiers, no ads, and no hidden charges.

Q: How is this different from Volume Master?
A: This extension combines volume boosting with video speed control, bass boost, and voice enhancement — features that Volume Master does not include. It's two tools in one.
