A precision neuro-acoustic web app that moves your brain into the frequencies of focus, creativity, and cognitive sharpness.
Works best with headphones · No music · Pure science
High-frequency Gamma waves (40 Hz) firing in sync. This is where complex problems feel simple and distractions disappear.
A sluggish state. Your thoughts are heavy, your focus is fragmented, and the "zone" feels miles away.
Using precision neuro-acoustic audio, Hemi nudges your neural rhythms back to focus. We bridge the gap between where you are and where you need to be.
Meta-analysis confirming the efficacy of binaural auditory beats on cognition and memory.
Garcia-Argibay et al., 2019 — Psychological ResearchHigh-frequency binaural beats bias the cognitive-control state towards focused attention.
Colzato et al., 2017 — Psychological ResearchSignificant changes in brainwave entrainment and mood states observed after just 15 minutes of auditory beat stimulation.
Chaieb et al., 2015 — Frontiers in PsychiatryA decade of research demonstrating that 40Hz gamma entrainment stimulates neural synchronization.
Iaccarino et al., 2016 — Nature (MIT Picower)Most focus music works by making you feel something. Hemi works differently.
Neuro-acoustic entrainment is the science of synchronizing brainwaves to precise frequencies using sound. By delivering carefully offset tones to each ear, Hemi creates an auditory signal that guides your neural oscillations into the exact state you need — deep focus, creative flow, calm alertness.
No rituals. No learning curve. Put on your headphones. Your brain does the rest.
Presents slightly different frequencies to each ear. The brain compensates by perceiving a third tone, guiding your brainwaves into targeted states.
Regular beats of a single tone that turn on and off rapidly. This creates strong auditory evoked potentials to synchronize neural activity.
A carefully tuned background sound environment (brown noise, rain, white noise) that masks distractions, reduces listener fatigue, and enhances the effectiveness of the entrainment tones. Users can blend the ambient layer to their preference.
Your brain operates across different frequency bands depending on your state of consciousness. Hemi isolates and amplifies the specific frequencies required for your task.
High-level information processing, cognitive enhancement, and memory recall. Ideal for complex problem-solving.
Alert, attentive, and engaged state. The standard frequency band for analytical thinking and sustained deep work.
Relaxed, lucid, and calm. Bridges the gap between conscious thinking and subconscious creativity. The "flow state" frequency.
Deep meditation, intuition, and memory consolidation. Used for stress reduction and mental resets.
The slowest brainwaves, dominant during dreamless sleep. Essential for physical healing, immune system restoration, and neural recovery.
Each profile uses a layered acoustic environment: a binaural beat as the foundation, isochronic tones layered on top for stronger neural entrainment, and an ambient background layer (such as brown noise, rain, or white noise) that you can mix to preference.
Sustained analytical focus for complex, demanding tasks.
Relaxed awareness and creative thinking.
Gamma stimulation optimized for information retention and recall.
Reduce anxiety while maintaining gentle attention.
Deep rest and neural recovery.
Fast-acting alertness and mental activation.
