Bass Booster EQ

Bass Booster EQ is a clean, ad-free 5-band equalizer with system-wide bass boost, 3D virtualizer, and loudness enhancer for Android. Enhance music in any app — Spotify, YouTube Music, podcasts, games, or video players — with real-time audio effects you fully control.   KEY FEATURES • 5-band graphic equalizer with ±15 dB range per band • Bass Booster with 0–100% adjustable strength • 3D Surround (Virtualizer) — wider stereo image on headphones • Loudness Enhancer — increase perceived volume beyond device max • 10 built-in presets: Normal, Classical, Dance, Flat, Folk, Heavy Metal, Hip Hop, Jazz, Pop, Rock • Save unlimited custom presets with your own names • Master power toggle — instantly enable or disable all effects • Persistent state — your settings restore on every launch • Clean dark UI with smooth animations • Optional haptic feedback on every interaction   NO ADS, NO TRACKING, NO ACCOUNTS We do not collect any data. No analytics. No third-party trackers. No signup. No internet permission required. All your presets and settings are stored locally on your device only. HOW IT WORKS   Bass Booster EQ uses Android's built-in audio effect APIs to process all audio playing on your device — not just one app. Start playback in your favorite music, video, or podcast app, then open Bass Booster EQ to shape the sound in real time. Everything plays the same — just better.   PERMISSIONS   • Modify audio settings — required by Android to apply audio effects • Vibrate — optional haptic feedback (can be disabled in Settings)   COMPATIBILITY Works on stock Android and most OEM ROMs. Some heavily customized ROMs (certain Samsung One UI, Xiaomi MIUI, Oppo ColorOS builds) intercept the audio effect chain via their vendor sound enhancements. For best results, disable other equalizer apps and any vendor "audio enhancement" feature in your device sound settings. Requires Android 7.0 (Nougat) or higher. Works with both speakers and headphones; the 3D Surround feature is most effective with headphones.   GETTING STARTED   1. Start playback in any music or video app 2. Open Bass Booster EQ 3.
