What It Is

allEQ is an open-source, rootless system-wide audio equalizer for Android built with modern Jetpack Compose and powered by Shizuku.

It attaches directly to the Android Audio HAL (Session 0) to provide low-latency, system-wide acoustic correction for built-in speakers, wired headphones, Bluetooth headsets, and external USB DACs.

Package name: com.omix.alleq
Maintainer: @omixin
Architecture: 100% Kotlin, Jetpack Compose, Material 3, Android DynamicsProcessing & AudioEffects API

Why This Exists

Most existing equalizer applications on Android face one of three fundamental problems:

Root requirement: Advanced DSP tools (such as ViPER4Android) require Magisk/KernelSU root, tripping SafetyNet/Play Integrity and making banking apps inaccessible.
Aggressive background killing: Non-root equalizers often rely on NotificationListenerService or accessibility hacks. Aggressive OEM task killers (MIUI, HyperOS, OneUI, OriginOS) terminate them within minutes of audio playback.
Muffled vocals during bass boost: Traditional equalizers simply boost lower frequencies, causing the phone's hardware amplifier protection to squash master volume and muffling speech and dialogue in videos.
Bloat and trackers: Commercial equalizers frequently package invasive analytics, full-screen advertisements, and subscription paywalls.

allEQ was built to solve these problems directly:

Rootless Session 0 Hook: Hooks directly into AudioEffect(AUDIO_SESSION_OUTPUT_MIX) via Shizuku-elevated permissions (MODIFY_AUDIO_SETTINGS), applying EQ globally across all applications without root.
Smart Dynamic Bass & Vocal Protection: Integrates an adaptive limiter (-1.5 dBFS brickwall) and dynamic mid-frequency compensation (+1.5 dB on 800–3000 Hz) so speech in podcasts, TikTok, and YouTube stays intelligible when sub-bass is boosted.
100% Offline & Private: The app has zero network permissions (android.permission.INTERNET is not declared). Zero analytics, zero telemetry, zero trackers.
Zero Passive Battery Drain: Operates via native Audio HAL effects without maintaining continuous CPU wake-locks or audio re-encoding pipelines.

Key Features

Audio DSP Engine

10-Band Graphic Equalizer: Studio-calibrated frequency bands (31 Hz, 62 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, 16 kHz) with smooth cubic Bézier curve visualization.
Tactile Capsule Faders: Vertical swipeable faders for Bass Boost (0–100%) and Pre-Amp (-12 dB to +12 dB) with haptic feedback steps.
Smart Dynamic Bass: Volume-adaptive mid-bass punch at lower volumes with high-volume cone excursion protection to eliminate speaker distortion.
Speech Leveller & Vocal Guard: Baseline gain floor and mid-band lift to keep dialogue crisp across videos with varying sound masterings.
Instant A/B Bypass: Hold the comparison button to temporarily bypass all DSP processing and compare directly with the uncolored sound.

Interface & Theming

Expressive Studio UI: Benzin bold headers and Wix Madefor Display body typography inspired by studio mixing consoles.
Color Accents: Emerald Green, Electric Cyan, Vivid Orange, Studio Purple, System Material You, or Custom Hex Accent.
UI Scaling: Three density presets (Compact 85%, Standard 100%, Large 115%) ensuring comfortable hitboxes on both compact phones and large displays.
Preset Manager: Create, reorder with drag-and-drop (☰), delete, and restore built-in or custom presets.

Privacy & System Integration

100% Offline: No internet permissions declared in AndroidManifest.xml.
OEM Whitelist Integration: Automated background battery-saving whitelist via Shizuku shell.

How Shizuku is used

Can keep the equalizer alive in background via battery whitelist shell commands through Shizuku in `cmd deviceidle whitelist`.

This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Shizuku is used only to keep the equalizer service running in the background, not to apply audio effects which use the standard system audio APIs.

Keep service alive: tapping the background protection action exempts the app from battery and background restrictions with privileged shell commands run through Shizuku, including allowlisting it from idle optimization, allowing background and foreground operation, and marking it active.

Android APIs or commands used

cmd deviceidle whitelist
cmd appops set RUN_IN_BACKGROUND allow
cmd appops set RUN_ANY_IN_BACKGROUND allow
cmd appops set START_FOREGROUND allow
am set-standby-bucket active

Notable details

The equalizer itself does not use Shizuku in code, it attaches to the global output mix and per app sessions with the normal audio effect APIs. The same protection screen also offers the normal system battery optimization prompt, which works without Shizuku.
