Volume Booster

Volume Booster — System-wide Audio Amplifier

Boost your device's volume beyond the maximum system limit. Perfect for listening to music, watching videos, or gaming when the default volume isn't loud enough.

KEY FEATURES

★ System Volume Control — Fine-tune your media volume from 0% to 100% with a smooth slider and precise +/- controls.

★ Amplifier Boost — Boost audio output up to 100% (15dB gain) with real-time visual feedback. Includes safe, boost, and redline status indicators.

★ Mono/Stereo Mode — Switch between stereo (L/R balanced) and mono audio output for your listening preference.

★ Home Screen Widget — Control volume boost directly from your home screen without opening the app. Toggle boost on/off, increase or decrease volume with one tap.

★ Notification Controls — Manage boost from the notification bar with quick action buttons.

★ Output Device Detection — Automatically detects and displays your current audio output (speaker, Bluetooth, wired headphones).

HOW IT WORKS

Volume Booster uses Android's DynamicsProcessing API (API 28+) for high-fidelity audio gain. On older devices, it falls back to LoudnessEnhancer for compatibility.

IMPORTANT NOTES

- Using high boost levels for extended periods may damage your hearing or speaker hardware. The app includes safety warnings at extreme levels.

- Boost applies globally to all media audio on your device.

- For best results, use with wired headphones or external speakers.
