Flagship Architecture

Up to 128-Band BiQuad Engine & Analog Radio Tuner

Standard equalizers use harsh, stepped graphic bands that distort phase. Ultra EQ generates continuous Hermite mathematical spline curves with raised, high-contrast studio ring-nodes for surgical frequency control across 3 to 128 bands.

Vintage Radio Slider: Switch between 3, 5, 10, 16, 32, 48, 64, and 128 bands to fluidly transition from broad acoustic mastering to surgical notch filtering (with 128 bands being the highest tier).
Tactile Studio Ring-Nodes: Raised outer bezels and white center pins give tactile target feedback on touch displays.
Full < Undo | Redo > History: Experiment fearlessly with non-destructive state undo stacks.

Streaming Intelligence

Lossless Playback & Live SoundCloud Integration

Experience your streaming music through an authentic analog turntable aesthetic. Ultra EQ's background media engine automatically syncs with SoundCloud, Spotify, Apple Music, and local FLAC players.

Edge-to-Edge Lossless Telemetry: Real-time readout of 192 kHz sample rates, 32-bit float resolution, and active DSP filters.
One-Tap Quick Launch: Tap the centered SoundCloud badge to seamlessly open the streaming app.
Clean Matte Platter: Precision dark vinyl platter with spinning groove animation and real-time hardware transport controls.

Binaural Acoustic Modeling

3D Spatial Soundstage Matrix & Room Reverb

Break free from flat, fatiguing headphone stereo. Ultra EQ's 3D Spatial Stage models real-world acoustic listening environments with binaural Head-Related Transfer Functions (HRTF).

Interactive 3D Orbit: Drag virtual speaker satellites and listener coordinates in real-time space.
Acoustic Environments: Switch instantly between Mastering Studio, Live Club, Concert Hall, and Cathedral acoustics.
Crossfeed & Haas Effect: Natural ear-to-ear bleed eliminates listener fatigue during multi-hour sessions.

Precision Control

Audiophile Settings & Luxury Color Palettes

Customize your acoustic chain down to the buffer sample size, lookahead peak limiter, and aesthetic studio theme.

Luxury Studio Themes: Obsidian Gold, Cyberpunk Neon, Studio Silver, Deep Blue, and Emerald Glow.
Zero-Clipping Limiter: Soft-knee lookahead limiter prevents harsh digital clipping during high-gain listening.
Low CPU Overhead: Native C++/SIMD processing consumes less than 1.5% CPU battery drain.

Frequently Asked Questions

Everything you need to know about Ultra EQ setup and compatibility.

How does Ultra EQ connect to my streaming apps?

Ultra EQ uses Android's native Notification Listener Service and dynamics processing architecture. It automatically detects audio streams from SoundCloud, Spotify, YouTube Music, Apple Music, and local FLAC players.

Does Ultra EQ require root access?

No root is required. Ultra EQ operates within standard Android audio frameworks on Android 10 through Android 15+.

Will it drain my battery?

No. The BiQuad DSP engine is compiled natively in C++ with ARM NEON SIMD acceleration, consuming less than 1.5% CPU during full 32-band real-time filtering and 60 FPS spectrum rendering.

Can I use it with Bluetooth headphones, DACs, and wired IEMs?

Yes. Ultra EQ automatically detects active audio output endpoints and calibrates sample rates up to 192 kHz / 32-bit lossless audio.
