Audio Booster Pro — スマート音量ブースター 作成者: Bulk Image Downloader

Transform Your Browsing with a Smart Audio Enhancement Suite
Tired of quiet YouTube videos, quiet dialogue in Netflix movies, and sudden ear-blasting ads? Audio Booster Pro is not just another simple volume slider that makes your audio crackle and distort. It is a premium, lightweight, offline-first sound enhancement suite for Firefox that gives you studio-quality control over your browser's audio.

Built on standard Web Audio API technology, Audio Booster Pro uses advanced compressor algorithms to boost audio up to 600% safely while keeping it crystal clear.

🚀 Key Features
🔊 Distortion-Free Smart Volume Boost (Up to 600%)
Most free volume boosters simply multiply the audio wave, causing muddy bass, crackling speakers, and distorted dialogue. Audio Booster Pro features an active Dynamics Compressor (Soft Limiter) that caps volume spikes before they distort, keeping your audio clean even at maximum boost.

⚖ Auto Volume Normalization (Smart Leveling)
Stop constantly adjusting the volume slider between different videos, songs, or streaming sites. Our real-time RMS audio analyzer automatically levels out the volume, bringing up quiet whispers and capping loud explosions so you get a smooth, consistent listening experience.

🎛 5-Band Parametric Equalizer & Audio Presets
Fine-tune your audio with our professional equalizer or toggle between built-in presets optimized for daily use:

Movie Mode: Boosts mid-range frequencies (1kHz–4kHz) to make dialogue clear while limiting sudden action sound effects.
Voice/Podcast Mode: Enhances speech clarity and cuts low-end rumble.
Bass Booster: Delivers deep, rich low-end frequencies with a built-in safe ceiling to prevent speaker damage.
Music Mode: Opens up the soundstage with custom EQ curves.
Night Mode: Automatically limits maximum volume after hours (defaults to 10 PM) to protect your ears and housemates.
💾 Per-Site & Per-Tab Volume Memory
Firefox remembers your preferences. Set a specific boost level and EQ profile for YouTube, and a different one for Netflix or Spotify. Audio Booster Pro automatically restores your settings whenever you return to the site.

🎧 Dedicated Bluetooth Profile
Bluetooth headphones are often quieter than wired outputs. Audio Booster Pro automatically detects your audio output device and applies an optimized volume offset to keep your Bluetooth sound punchy.
