Tonemorph Parametric Equalizer

Most mobile equalizers lock you into five or ten rigid sliders with fixed frequencies. You cannot choose the exact frequency causing harshness in your headphones, and you cannot narrow the bandwidth to fix it without muffling the rest of your music.

Tonemorph EQ brings true desktop-grade parametric equalization to Android. Take total acoustic command of your sound with up to 64 surgical filter nodes, 7 studio filter types, full 20 Hz to 20,000 Hz spectrum control, and an active signal inspector.

DESKTOP-GRADE PARAMETRIC EQUALIZER (PRO MODE)

Shape your sound with the precision of a recording studio console:

• Complete Frequency Freedom: Place filter nodes at any exact frequency across the entire 20 Hz to 20 kHz spectrum. Fix a sharp 6,200 Hz headphone treble spike or shape a tight 38 Hz sub-bass punch with equal ease.

• Surgical Q Factor Control (0.10 to 10.0): Adjust filter bandwidth with two-finger pinch gestures or precision steppers.

• 7 Professional Filter Topologies:

1. Peaking (PK): Bell curves for targeted frequency adjustments.

2. Low-Shelf (LS): Uniform boost or cut across the low end.

3. High-Shelf (HS): Clean extension for treble presence and air.

4. High-Pass (HPF): 12 dB/octave cut to remove unwanted sub-bass rumble.

5. Low-Pass (LPF): 12 dB/octave cut to tame extreme high-frequency hiss.

6. Notch (NO): Surgical cutouts to eliminate headphone sibilance peaks.

7. Band-Pass (BP): Constant 0 dB peak passband.

• Interactive Spline Canvas: Watch your composite acoustic curve update in real time with an accurate mathematical transfer function. Badges ride directly on the wave with vertical alignment stems.

• Equal Acoustic Zones: Dividing the spectrum into equal logarithmic zones guarantees smooth finger tracking with dedicated zone ownership, preventing crowded node collisions.

ACTIVE HEADROOM GUARD (AUTO PRE-AMP)

Boosting parametric nodes increases digital signal levels and can cause harsh digital clipping at your DAC.

• Automatic Attenuation: When positive boosts exceed 1.5 dB, Auto Pre-Amp gently attenuates master input level.

• Dynamic Recovery: Lowering your EQ bands prompts the Pre-Amp to track upward back toward 0.0 dB automatically.

• Zero Clipping Risk: Backed by a 72-sample linked true-peak lookahead limiter in native C++ to catch fast transients before they distort.

6,033 CALIBRATED HEADPHONE PROFILES (AutoEQ)

Correct the raw frequency response of your specific headphones or IEMs to the laboratory Harman Target:

• Pre-indexed profiles from Oratory1990, Crinacle, Rtings, and Innerfidelity.

• Top models ready offline (Sony WH-1000XM4/5, AirPods Pro, Sennheiser HD600/650, Bose QC, Moondrop, Truthear).

• 1-tap apply loads official parametric biquads and recommended preamp offsets into the engine.

AUDIO PIPELINE TRANSPARENCY INSPECTOR

Inspect what Android AudioFlinger and your hardware DAC are actually doing with your music:

• Source: Active playback app (Spotify, YouTube Music, Apple Music, TIDAL), track title, and sample rate.

• DSP: 32-bit floating point processing status and active filter topologies.

• Resampler: Verifies whether Android is running an active Sinc Resampler (SRC) or delivering a 1:1 bit-perfect signal.

• Sink: Maximum DAC hardware rates and active Bluetooth codecs (Sony LDAC up to 990 kbps, Qualcomm aptX HD, AAC, SBC).

BUILT FOR REAL WORKFLOWS

• Easy Mode Option: Quick 3-knob macro tone dials (Bass, Vocal, Treble) or 10-band ISO sliders when you want immediate adjustments.

• Hardware Auto-Routing: Auto-bind custom EQ presets to specific Bluetooth MAC addresses or USB DAC IDs. Connect your headphones and your tuning applies instantly.

• Import and Export: Full compatibility with EqualizerAPO text and Wavelet 127-point GraphicEQ configs, plus complete JSON backup and restore.

• 100% Free: No paywalls, no trial limits, and no locked filter bands.
