Hertz Labs generates frequency signals in real time - live, pure sine wave stereo pairs computed directly on-device via a custom C++ DSP engine. Never sampled or compressed; what you dial is exactly what your brain receives. Unlock clinical-grade audio architecture designed to seamlessly bridge advanced laboratory science with daily mindfulness. WHAT IS BRAIN ENTRAINMENT? Your brain synchronizes electrical activity with external stimuli via the Frequency Following Response (FFR). Binaural beats deliver distinct tones to each ear; the auditory cortex perceives the difference as a phantom internal beat, safely shifting your brainwave state. Hertz Labs covers the full spectrum from Infra-Slow (under 0.5 Hz) to Hyper-Gamma (500 Hz) with zero artificial ceilings. 7 ADVANCED ENGINE MODES Binaural / Dichotic: Phantom internal beat. Requires headphones. Hemispheric Sync: Phase-aligned signals for brain coherence. Phase Alignment: Continuous phase shifting for isochronic entrainment. Pitch Modulation: Frequency-domain carrier modulation. Acoustic Resonance: Speaker-friendly mode (no headphones required). Ambient Modulation: Low-intensity background entrainment. Music-Reactive: Tracks live external audio dynamically. UNRESTRICTED FREQUENCY SPECTRUM (FREE ACCESS) Delta to Gamma (0.5-40 Hz): Standard clinical bands for sleep, calm, and focus. (PREMIUM UNLOCK) Epsilon (0-0.5 Hz): Ultra-slow neuro-binding studied in trauma research. Lambda (80-150 Hz): High-frequency neuro-binding for cognitive processing. Supra-Gamma (150-280 Hz): Exotic high-state synthesis bands. Omega / Hyper-Gamma (280-500 Hz): Unrestricted scientific range. MATH MODE & CUSTOM FORMULAS Mathematical, physics, and traditional tuning presets: Schumann Resonance (7.83 Hz): Earth's electromagnetic baseline. Golden Ratio (Phi = 1.618): Proportional harmonic intervals. Fibonacci Sequences: Integer series mapped as frequency deltas. Solfeggio Scale: Ancient acoustic wellness frequencies (396Hz-852Hz). Alpha Baseline (10 Hz): Standard reference for alert calm. Premium: Custom Formula Input using Pi, Phi, and Fibonacci constants evaluated live. AI-POWERED GUIDE Describe your goal in plain English - "help me focus for coding" or "quiet my mind for sleep." The integrated AI processes your intent and configures the optimal engine mode, carrier tone, and target frequency. Zero technical knowledge required. ADDITIONAL TECH FEATURES 100% Offline: On-device computation. No internet required. True Background Audio (Premium): Layer beneath Spotify/Apple Music or play locked. Kinetic Mode: Gyroscope modulates parameters via physical body movement. Parametric Control: Fine-tune carrier Hz, beat Hz, volume dB, stereo angles, and drift. WHO USES HERTZ LABS? Students & Professionals: Alpha/Beta entrainment for deep work and focus. ADHD Management: Structured training to assist with calming mental noise. Meditators: Precise Theta/Delta targeting for deep inner exploration. Biohackers & Athletes: High-intensity Gamma, Epsilon, and Lambda states.

Hertz Labs is a brainwave frequency generator that produces pure sine wave stereo pairs in real time. It uses the principle of brainwave entrainment to help users achieve specific mental states like focus or sleep. ### How does Hertz Labs work? The app generates distinct tones to each ear, and the auditory cortex perceives the difference as a phantom internal beat. This process, known as the Frequency Following Response, safely shifts your brainwave state. ### Does Hertz Labs require headphones? The Binaural/Dichotic engine mode requires headphones. However, the Acoustic Resonance mode is speaker-friendly and does not require headphones. ### Can I use Hertz Labs offline? Yes, Hertz Labs operates 100% offline. All computations are performed on-device, so no internet connection is required for its core functionality. ### What are the premium features in Hertz Labs? Premium unlock provides access to advanced frequency bands like Epsilon, Lambda, Supra-Gamma, and Omega/Hyper-Gamma. It also enables true background audio playback and custom formula input. ### How much does Hertz Labs cost? The app is free to download and use with access to standard clinical bands. Premium features are available through monthly or annual subscriptions, starting at $4.99/month with a 7-day free trial. ### Is Hertz Labs suitable for all ages? Hertz Labs has an age rating of 4+, making it suitable for a wide range of users. The AI guide can help tailor settings for specific needs, from students to those managing ADHD. ### How often is Hertz Labs updated? The app was last updated on July 7, 2026, with version 3.0.
