Description
Transform your Android's sound into a professional audio experience.
The Perfect Sound is the most advanced system equalizer for Android. It doesn't just tweak bass and treble: it's a complete DSP (Digital Signal Processing) engine that intercepts and processes audio at the system level, working with any music app, video streaming service, game, or call.
Whether you listen with Bluetooth headphones, USB earphones, wired headsets, or your phone's speaker, The Perfect Sound automatically detects the connected device and applies the optimal audio profile. No manual setup required: it adapts to you.
Five audio engines, one app
🔹 TPS — The Perfect Sound (Premium) The heart of the app. A complete audio engine with 3-band Pre/Post EQ, 3-band multiband compressor (MBC), professional limiter, stereo virtualizer, and loudness enhancer. Choose from 7 optimized sound profiles (Balanced, Bass Boost, Voice, Night, Movie, Music, Speaker) or create up to 20 custom profiles.
🔹 AutoEQ (Premium) Access over 6,000 frequency correction profiles for the world's most popular headphones, based on the AutoEQ database. Download the specific profile for your headphone model and get a flat, balanced frequency response in seconds. Includes automatic suggestion system on Bluetooth connection.
🔹 Parametric EQ (Premium) For audiophiles. Up to 30 parametric filters with 7 filter types: Peaking, Low Shelf, High Shelf, Low Pass, High Pass, Band Pass, and Notch. Advanced biquad coefficient calculation with real-time frequency response visualization. Export and share your profiles.
🔹 Graphic EQ Classic equalizer with 5, 15, or 31 bands (31-band is Premium). Intuitive vertical sliders with haptic feedback, double-tap to reset, and customizable per-device profile library.
🔹 Maximizer Boost perceived volume up to +10 dB using the system's Loudness Enhancer. Ideal for noisy environments or giving your music more presence.
Smart. Automatic. Personal.
✓ Smart device detection — Automatically recognizes Bluetooth, USB, wired headphones, and speakers, loading the dedicated EQ profile for each device. ✓ Smart mutual exclusion — Activating one equalizer automatically disables the others to avoid audio conflicts (Maximizer is compatible with Graphic, Parametric, and AutoEQ). ✓ Full Google Drive backup — Save all settings, custom profiles, and preferences in a ZIP archive. Restore to any device in a few taps. ✓ Total theming — Material 3 with dynamic color (Android 12+), light/dark/AMOLED modes, and customization of 16 color roles for an interface that's truly yours. ✓ Quick Settings Tile — Enable or disable the equalizer directly from the system quick panel. ✓ Frequency visualizer — Real-time graph of the applied frequency response. ✓ 55+ genre presets — Rock, Pop, Electronic, Hip Hop, Jazz, Classical, Metal, and many more.
Why The Perfect Sound is different
Unlike simple 5-band equalizers, The Perfect Sound leverages the native Android DynamicsProcessing API with up to 128 equalization bands, offering unprecedented granular control on a mobile device. The foreground service architecture ensures audio processing stays active even when the app is in the background, without interruptions.
Requirements & Compatibility
• Android 10 (API 29) or higher • Optimized for Android 15 • Works with any audio/video app • Some advanced features require a one-time Premium purchase
Permissions (Transparency)
The app requests the RECORD_AUDIO permission to access the system audio stream required for audio visualizer dock. We do not record or transmit any audio: all processing happens exclusively locally on your device. Bluetooth permission is required for automatic headphone detection.

it's good but you can't fully customize it without paying
★★☆☆☆Mindaugas Akramas· Nov 25, 2025
Looks promising but only loudness adjusting (1 out of 2 features available) are working. Graphic EQ throws a bunch of errors in the snack bar. No free trial. At least somewhat limited access to the premium features would be acceptable just to see what you're getting before paying €4.99. Also, you should specify why you need certain permissions (like microphone) before requesting.
Each subscription will automatically renew 3 days before the expiration date for
