YouTube Pro: Audio Enhancer
Cinema-quality sound with a professional 5-band EQ and multiband compressor.
A sophisticated userscript that injects a studio-grade audio processing engine directly into YouTube. It transforms flat, compressed audio into a deep, clear, and balanced soundstage without breaking YouTube’s interface or performance.
Designed with a "Native UI" approach, the button blends perfectly with YouTube's modern player controls.
🌟 Key Features
- 🎚️ Professional 5-Band EQ: Tuned specifically for music and cinematic content.
- 🎧 Studio-Grade Mastering: Automatic "Mud-Cut" and "Brilliance" processing.
- 🔊 Smart Compression: Balances dynamic range without distortion (Soft Limiter).
- 🎨 Remastered UI: A "pill-shaped" button that matches YouTube's 2024/2025 aesthetic.
- ⚡ Zero Latency: Uses the Web Audio API for real-time local processing.
- 🧠 Smart Persistence: Remains active and stable across video navigation (SPA support).
🎛️ The Audio Engine (How It Works)
Unlike simple bass boosters, this script uses a complex Mastering Chain to enhance audio quality:
- Sub-Bass (60Hz): Adds deep, thumping low-end without muddying the mix.
- Mud-Cut (250Hz): Removes the "boxy" or "cardboard" sound to clean up the audio.
- Vocal Presence (2.5kHz): Brings vocals and lead instruments to the front.
- Brilliance (8kHz): Adds "air" and high-end sparkle for crystal-clear detail.
- Dynamics Compressor: A musical compressor that glues the sound together and prevents clipping.
All processing is done locally within your browser—no external servers, no lag.
