A science-backed frequency generator built on the Web Audio API. Mathematically precise binaural beats, Solfeggio tones, and healing frequencies — free, ad-free, and yours.
A complete tour of the frequency generator, visual studio, vocal recorder, binaural presets, Solfeggio tones, and recording tools — everything in one demo.
Select a brain state, layer harmonic overtones, play the healing keyboard, and export studio-quality WAV files — all running locally in your browser.
Want video? Open the Visual Studio — sacred geometry visuals + word overlays + binaural audio, all recorded together →Schumann resonance (7.83 Hz) — Earth's natural electromagnetic frequency. Theta-alpha border: the most receptive state for meditation and subconscious programming.
Activate one or more — they layer as pure sine tones. Works on speakers or headphones.
No frequencies active
Harmonic overtones above the active frequency. Included in all WAV exports.
The perfect fifth (×1.5) is the most universally resonant interval across every musical tradition.
Click keys to play. Binaural mode: left = note, right = note + beat frequency.
Broadband ambient layers. None interfere with binaural Hz — they occupy different frequency mechanisms. Stack freely over any binaural or solfeggio session.
Filtered white noise — sounds like rain. The most studied noise type for relaxation and sleep. Doesn't contain specific Hz that conflict with binaural.
Deeper, warmer rumble. Like a river or distant thunder. Higher energy in lower frequencies — more grounding, pairs well with delta/theta work.
Six-oscillator tonal drone in harmonic ratio to the active carrier. Subtle LFO creates natural breathing variation. Rich, meditative texture.
Smoothly varies the volume of each active layer at the chosen interval — creating naturally shifting soundscapes rather than static levels.
Science-backed audio therapies. Each is stackable — run any combination alongside binaural beats or solfeggio.
A single tone pulsing on/off at the target frequency — the speakers-compatible alternative to binaural beats. Produces brainwave entrainment through amplitude modulation, not stereo channel separation.

5–6 breath cycles per minute is clinically proven to maximize heart rate variability, reduce cortisol, and activate the vagal brake. Gentle audio tone guides each inhale and exhale.
A tone that alternates left and right in stereo at 1–4 Hz. Mimics the bilateral stimulation used in EMDR therapy. Clinically validated for anxiety, PTSD, and emotional processing. Headphones required.
MIT researcher Li-Huei Tsai's lab used a direct 40 Hz isochronic tone (not binaural) combined with 40 Hz visual flicker. Early human trials show reduction in Alzheimer's markers. This is that exact protocol — a pure 40 Hz amplitude pulse at 440 Hz carrier. Works on speakers.

Five oscillators with non-integer bowl partials (1×, 2.756×, 5.017×, 8.2×, 12.3×) and exponential decay envelopes. Clinically studied for cortisol reduction. Strike manually or auto-sequence.
136 Hz (the "Om frequency") with harmonics. Sustained humming at this frequency vibrates the vagus nerve directly via bone conduction and chest resonance. The vagus nerve governs rest-and-digest, heart coherence, and immune regulation. Hum along for maximum effect.
Hum along at this pitch. The bone conduction from your own voice amplifies the vagal activation significantly.
Generates a mathematically precise WAV file. Import into GarageBand, Audacity, or any DAW and record your affirmations on top.
Earth's natural electromagnetic frequency — measurable from anywhere on the planet. Our Schumann preset encodes 200 Hz left, 207.83 Hz right, producing the exact 7.83 Hz phantom beat in your brainstem.
Theta brainwaves (4–8 Hz) are the state of deep meditation and maximum subconscious receptivity. Binaural beats bring the brain here within 6–8 minutes — the optimal window for affirmation work.
The most studied Solfeggio frequency. A 2018 study found it reduced anxiety markers. FrequencyNova generates it as a mathematically precise pure sine wave.
MIT research found 40 Hz gamma stimulation reduces Alzheimer's markers in early human trials. FrequencyNova's Gamma preset encodes this as a binaural beat.
