## What is 40Hz Gamma?

40Hz Gamma — Advanced Brain Stimulation

Experience the future of cognitive wellness with 40Hz Gamma, a professional tool designed for multisensory 40Hz stimulation. Grounded in modern neuroscience research, our app provides precisely calibrated audio and visual signals to help you reach states of deep focus and tranquility.

Key Features

Professional Audio Modes: 
- **Standard Gamma Base (Pure Tone)**: The cleanest 40Hz signal for baseline training.
- **Strong Pulsatile Rhythms (Isochronic)**: Sharp rhythmic pulses for powerful engagement.
- **Inter-Hemispheric Sync (Binaural Beats)**: Guides hemispheric synergy via precision frequency offsets.
- **Envelope Neuromodulation (AM)**: Smooth 40Hz amplitude modulation of a high-frequency carrier.
- **Monotic Summation (Monaural Beats)**: Creates physical interference through combined signals in each ear.

Advanced Gamma Visuals: 
- **Global Sync (Square Wave)**: Uniform full-field stimulation for standard synchronization.
- **Harmonic Fade (Sine Wave)**: Smooth sinusoidal transitions for a gentler experience.
- **V1 Cortex Drive (Drifting Grating)**: Uses directional motion to strengthen primary visual cortex activation.
- **Centric Focus Pulse (Radial Pulse)**: Expanding patterns for centering focus and attention.
- **High-Sensitivity Entrainment (Checkerboard)**: Maximizes response using high-contrast phase inversion.
- **Multi-Dimensional Integration (Mixed Mode)**: Blends patterns dynamically to prevent neural adaptation.

Precision Tuning: Fine-tune the stimulation frequency between 38Hz and 42Hz (default 40Hz) in settings to find your optimal resonance.

Rich Ambient Library: High-quality white noise including Rain, Ocean, Forest, and more.

Advanced Mixer: Seamlessly blend 40Hz waves with your favorite ambient sounds.

Privacy First: Fully offline, no data collection, and no trackers.

### How often is 40Hz Gamma updated?

The latest version of 40Hz Gamma is 1.3.2, which was last updated on May 27, 2026. This indicates a relatively active development cycle.

## Version history (last 5 releases)

### 1.3.2 — 2026-05-27

• Custom Light Color: Choose your own flicker color with a one-tap color picker
• Bug fixes and stability improvements

### 1.3.1 — 2026-05-02

1. **Neuro-Function-Oriented Labels**: Intuitively understand the scientific benefits of each stimulation, allowing for precise selection based on your needs (e.g., V1 Cortex Drive, Inter-Hemispheric Sync).
2. **Restructured Mode Titles**: Implemented a "Functional Label + Technical Property" dual display, featuring detailed mechanistic subtitles.
3. **Comprehensive Science Update**: Re-wrote scientific principles for all 11 modes on the Info page, detailing how various geometric patterns impact the brain.

### 1.3 — 2026-04-28

Perfect Audio-Visual Sync
• Unified timing system ensures audio and visual stimulation stay perfectly synchronized
• No drift even during extended sessions
• Instant synchronization when starting both modes together

Enhanced Audio Quality
• Eliminated clicking sounds in Isochronic mode
• Smoother transitions between audio modes
• Improved phase consistency for better stimulation effect

### 1.2.1 — 2026-04-27

Phase Locking Integration: We've introduced a true millisecond-level synchronization mechanism between the 40Hz audio and visual stimulations. Whether you start audio or visuals first, the underlying engine automatically aligns their time axes. This perfect audiovisual beat lock ensures a more precise and immersive neural stimulation experience.

### 1.2 — 2026-04-25

New Audio Modes: Added professional audio stimulation modes (Isochronic, AM, Monaural, etc.) for a more comprehensive sensory experience.
New Visual Modes: Added professionally designed visual patterns including Drifting Gratings, Radial Pulse, and Checkerboard.
Full-Screen Support: Immersive full-screen visual stimulation to maximize the effect.
Frequency Fine-tuning: You can now precisely adjust the stimulation frequency between 38Hz and 42Hz in Settings.
