Every protocol, cited honestly.

Gradual transition from relaxed alpha (10Hz) to deep-sleep delta (1.5Hz). Delta-band stimulation before sleep is associated with enhanced slow-wave sleep and sleep-dependent memory consolidation.

Gamma-band (40Hz) auditory stimulation, inspired by the GENUS protocol from MIT (Tsai lab). In mice, 40Hz stimulation reduced amyloid plaques and engaged microglial activity; in humans it is being studied as a safe, non-invasive cognitive-health intervention. Framed as cognitive stimulation, not treatment.

Sustained theta (6Hz) entrainment associated with deep meditative states, relaxed introspection, and hypnagogia. Experienced meditators reliably show elevated frontal-midline theta.

Alpha entrainment (8–12Hz) is the most replicated EEG correlate of relaxed wakefulness. Consumer and clinical studies report reduced subjective anxiety and lower cortisol during and after alpha-band auditory stimulation.

Slow descent from theta (8Hz) into deep delta (0.5Hz). Use alongside your regular sleep hygiene — a tool, not a replacement for good sleep habits.

Sensorimotor-rhythm / low-beta (15Hz) range, the target band for focus-oriented neurofeedback. Associated with sustained attention and reduced mind-wandering.

Short descent to theta + return to alpha — designed around the 10–20min power-nap sweet spot that avoids sleep inertia from full NREM.

Five-minute palette cleanser at 10Hz alpha. Quick parasympathetic switch between meetings, after difficult conversations, or to break the doom-scroll loop.

Ten-minute respiration pacer at 0.1Hz (10s in, 10s out via 6 breaths/min). Targets the baroreflex resonance frequency — the strongest known acute booster of HRV.

Alpha-theta border (~7–8Hz) is the EEG signature Kotler and others associate with flow. Protocol primes the state before a deep-work block.

10Hz alpha audio paired with a 0.1Hz (~6 breaths/min) resonant-breathing target. HRV coherence at 0.1Hz is an established autonomic-balance marker (HeartMath Institute research).

Frontal theta (6Hz) is causally linked to working-memory maintenance. Useful for study blocks requiring heavy information retention.

Slow-oscillation (~0.75Hz) auditory stimulation during the descent into sleep has been shown to boost sleep-dependent memory consolidation in controlled studies. Use in the 15 min leading to lights-out.

Sustained 10Hz alpha with minimal frequency modulation — the simplest and most-replicated anxiolytic audio protocol in the consumer literature.

Alternating alpha down-regulation and gamma bursts mimics the EEG pattern found during divergent-thinking (creative) tasks.

Slow audio pacer at 0.1Hz (~6 breaths/min) — the resonant frequency of most adults' baroreflex. Used widely in HRV biofeedback for autonomic balance and stress resilience.

Twenty-minute gamma session pulsed across encoding windows. Gamma-band synchronization is the EEG marker of successful memory encoding — useful before high-information study or exam prep.

Theta + low-alpha cooldown to accelerate parasympathetic re-entry after exercise. HRV recovery within 10 minutes post-exercise predicts cardiovascular fitness.

Fifteen-minute sustained 40Hz session. Gamma synchrony binds working-memory representations across cortical regions.

Progressive alpha-to-theta descent (12Hz→4Hz). Classic pattern for trance induction; EEG studies of hypnotic states show elevated theta and reduced frontal alpha.

Low-frequency theta→delta pattern often used for general relaxation. Framed as a relaxation tool, not a pain-management device.

Alpha-theta border (7–10Hz) is associated with relaxed, emotionally-integrative states — the protocol used in Peniston-Kulkosky alpha-theta neurofeedback.

Short Beta-band session for waking up clearer. Beta activity correlates with alert wakefulness; pairing audio with morning light gives a sharper start.

Single Pomodoro (25 min) anchored at 13Hz SMR — the EEG band associated with calm, sustained attention. Designed to slot into any work / study rhythm.

Ninety seconds at 10Hz alpha — the shortest viable cortical reset. Designed to slot between consecutive Zoom calls, fast inbox triage windows, or as a 'pause' habit-stack cue.

SMR neurofeedback (12–15Hz, central scalp) improves attention and impulse control in clinical populations. Here delivered as auditory analog.

Short low-beta session designed for morning use to support the natural cortisol-awakening response. Best paired with daylight exposure.

Continuous 14Hz SMR session — the central rhythm enhanced in classic ADHD neurofeedback protocols. Not a medical treatment; intended as a focus aid alongside whatever protocol your clinician recommends.

Long alpha session (10Hz) at lower volume — alpha-band activity is reduced during migraine attacks; gentle stimulation may help during the prodrome / postdrome phase. Not a substitute for prescribed treatment.

Cycles between 13Hz SMR (attention anchor) and 16Hz mid-beta (active processing). Targets the two EEG bands implicated in efficient reading comprehension.

Sustained 7Hz frontal-theta session. The Default Mode Network engages during mind-wandering and creative incubation; theta-band activity tracks this state.

Long-form SMR session at 13Hz for deep-work blocks longer than a single Pomodoro. Holds the attention floor without spiking arousal.

Alternates 6Hz theta (emotional release) with 10Hz alpha (relaxed calm). Useful for anxiety states that don't yield to pure alpha alone.

Short 15Hz Beta primer before high-stakes performance — interview, pitch, public speaking, athletic event. Boosts felt activation without spilling into anxiety territory.

Short, sharp 10-minute primer designed to break the gravitational pull of procrastination. Lifts the activation floor enough to get started without overshooting.

Alternative tinnitus protocol cycling between 6Hz theta (default-mode quieting) and 10Hz alpha. Use with the Coherence research base frequency offset from your tinnitus pitch.

Twenty-five minute theta protocol designed for the 'wired-tired' state. Lowers cortical arousal toward sleep-onset architecture without forcing it.

A sustained 528Hz tone from the Solfeggio tuning system. There is no peer-reviewed evidence for health effects of 528Hz (nor the other Solfeggio frequencies), but many users find the tone pleasant for meditation. Presented honestly as tradition, not science.

7.83Hz is the fundamental frequency of the Earth-ionosphere cavity (Schumann resonance). Some practitioners find this frequency grounding for meditation. Claims of specific biological effects remain unproven.

A traditional ascending-frequency sequence rooted in yogic practice. Framed as spiritual / meditative work, not medical or neurological therapy.

Seven-segment journey through the tones traditionally associated with the chakra system in South Asian contemplative traditions. Respectful nod to the tradition, not a claim of physiological effect.

Sustained 963Hz, traditionally linked to the pineal / crown centres. The highest of the extended Solfeggio set. Tradition, not science.

Individual Root-chakra practice. 256Hz base with theta brainwave overlay. Traditional / spiritual framework; symbolic rather than physiological.

Individual Heart-chakra practice. 341Hz tone with light alpha-theta brainwave overlay. Traditional / symbolic — not a medical claim.

Individual Throat-chakra practice. 384Hz tone with mid-alpha overlay. Traditional framework — useful as a focused-tone meditation before expressive work.

Individual Crown-chakra practice. 480Hz tone with high-alpha overlay. Bright, light meditation — included honestly as a symbolic framework.

Alpha entrainment paired with a soft notch in the base-frequency band. Tailored notched-music therapy is an emerging, individualized approach to tinnitus — set your base frequency near (but not on) your tinnitus pitch.

Repeated high-gamma bursts (35–45Hz). Users report subjective effects ranging from alertness to unusual visual-mental states. Experimental — stop if you feel discomfort, and do not use if you have a seizure history.

Rapid alpha→theta descent aimed at the hypnagogic borderland — the brief 'image-rich' state between waking and sleep prized for creative insight.

Cycles between SMR (13Hz) attention anchor and 40Hz gamma bursts. Hypothesis: combine sustained attention with neural synchronization. Exploratory — let us know how it feels via the Report a Bug button.

Theta-alpha alternation designed to mirror REM-onset architecture and increase odds of dream awareness on wake-induced lucid dreams. Strictly exploratory — anecdotal user reports only.

Cycles 40Hz gamma with the 7.83Hz Schumann reference. Speculative pairing intended for advanced meditators. Stop if you feel discomfort.

Two-minute cycles between 10Hz alpha (low-effort attention) and 40Hz gamma (binding / insight). Speculative model of optimal flow-state EEG.
