Shape your mindset with customizable Brainwave Entrainment Stacks. Listen in Binaural, Monaural, Isochronic, or combined Binaural + Isochronic Tone Modes. Headphones are optional when listening to Monaural or Isochronic tones. Start with 100+ included Explore Stacks, or create your own by combining any of 300+ Multi-Stage Brainwave Entrainment programs with Guided Breathing and background audio elements into an integrated Stack. NeuralStack.io is designed for people who want more than fixed audio tracks. Instead of locking you into pre-made sessions and pre-mixed tones, NeuralStack.io provides advanced tone modulation and flexible tools to create custom soundscapes, so you can shape your ideal mindset for any situation. Includes 300+ advanced brainwave entrainment programs for focus, relaxation, stress relief, memory, insomnia relief, sleep, meditation, anxiety relief, and much more. Create custom multi-stage brainwave entrainment programs for your Stacks: * Add or remove stages, fine-tune stage durations. * Specify any beat frequency from 0.5–100 Hz. * Specify fractional frequencies with 2-decimal precision. * Choose carrier frequencies from 100–1000 Hz with automatic power equalization. * Listen in 4 Tone Modes: Binaural, Monaural, Isochronic, or phase-synchronized Binaural + Isochronic modes. * Supports Schumann Resonance frequencies (ex 7.83 Hz). Listen alongside other audio/video apps: * Set your preference to allow other apps at the app-level or the stack-level. Listen Offline: * Audio resources are synchronized to the device instead of being streamed, eliminating network traffic, saving battery life, and allowing you to listen offline. Guided Breathing: * Remix the included breathing programs to match your pace. * Create custom multi-stage breathing programs with adjustable tempo, text, and visuals. * Supports fractional breathing patterns, such as Coherent 5.5 second cycles. Advanced Global Settings * Use the app's Global Settings to modify tone characteristics, such as cycles-per-pulse and gain to sharpen or soften isochronic and monaural modulation. Stack Playlists * Organize your Stacks into playlists to support your daily routine. * Create sequences of Stacks that use different Tone Modes. Ambience and Nature * Layer dynamic ambience and nature sounds. * Remix programs, combining them to create multi-stage ambient and nature programs, and reuse them across different Stacks. Solfeggio and Schumann Frequencies * Includes single and multi-stage entrainment programs utilizing Solfeggio carrier frequencies and Schumann resonant beat frequencies to be remixed and customized. Color Noise * Layer a color noise element into your stack for sound masking and tinnitus relief. Pure Sine Waves * Create pure sine waves from 100 to 1000 Hz with power equalization and 2-decimal precision. * Remix and combine programs to create multi-stage Solfeggio progressions. Custom Audio Programs * Integrate personal audio files into your Stacks. * Note: This feature is only intended for personal audio files, such as those recorded with voice recording apps, and cannot access copy-protected audio or audio from streaming services.
