Brain Beats — precision brainwave audio

Three studio-grade audio tools for focus, sleep, and meditation — monaural beats and isochronic tones that work on any speaker, plus binaural beats for headphone sessions. Presets, noise overlay, and session tracking included.

🔊

Monaural Beats

The beat is mixed directly into the audio signal — works on any speaker or headphone, no stereo channel separation required.

  • No headphones required
  • 6 clinical presets (Delta → Gamma)
  • Real-time waveform visualizer
  • Session timer (5 – 60 min)

🎧

Binaural Beats

Slightly different frequencies sent to each ear — your brain perceives the difference as a beat. Requires stereo headphones for the effect to work.

  • Clinical presets + save your own
  • White, pink & brown noise overlay
  • Media & YouTube overlay
  • Session history log

Isochronic Tones

A single tone pulsed sharply on and off at the entrainment rate. Strong evoked response without headphones — many find these the most direct of the three.

  • No headphones required
  • Pulse shape: square, triangle, sine
  • Adjustable pulse depth
  • Presets, noise & media overlay

What you get
🎛️

Full Customization

Adjust base frequency (80–600 Hz), beat frequency (0.5–50 Hz), carrier waveform, and volume. Fine-tune to exactly what works for you.

🧠

5 Brainwave Bands

Quick presets for Delta, Theta, Alpha, Beta, and Gamma ranges with real-time band identification and descriptions.

📊

Live Visualization

Real-time waveform display powered by the Web Audio API analyser node. See the interference pattern as it plays.

🔊

No Headphones Needed

Unlike binaural beats, monaural beats mix externally. The amplitude modulation is in the signal itself — any speaker works.

⏱️

Session Timer

Set timed sessions from 5 to 60 minutes. Audio fades out automatically when your session ends.

Research
40-Hz binaural beats enhance training to mitigate the attentional blink
Read on PubMed ↗
Ross & Lopez  ·  Scientific Reports 10, 7002  ·  2020
The attentional blink is a well-documented cognitive gap: when your brain processes one piece of information in a rapid stream, it briefly “blinks” and misses the next one. This study tested whether 40 Hz binaural beats could accelerate training that reduces this blind spot. Participants performed a rapid attention task over three consecutive days while listening to either 40 Hz or 16 Hz binaural beats. MEG brain recordings confirmed that 40 Hz beats produced strong gamma entrainment — the brain's neural oscillations synchronized to the beat frequency. The key finding: 40 Hz stimulation accelerated the training benefit, but the gains didn't appear mid-session. They emerged overnight, after sleep — suggesting the beats support the memory consolidation process that happens while you rest.
Practically speaking: listening to 40 Hz binaural beats while doing focused cognitive work, then sleeping, may help your brain consolidate what it learned faster than it otherwise would.

Brainwave frequency guide
Delta δ
0.5 – 4 Hz Deep sleep · Healing · Recovery
The slowest brainwave frequency. Dominant during dreamless sleep and deep restorative states. Associated with physical healing, immune function, and the release of growth hormone.
Theta θ
4 – 8 Hz Meditation · Creativity · Insight
Present during deep meditation and the hypnagogic state between waking and sleep. Linked to vivid imagery, intuition, and creative breakthroughs. Often the target for experienced meditators.
Alpha α
8 – 13 Hz Relaxation · Calm focus · Flow
The bridge between conscious thinking and the subconscious mind. Dominant when you're relaxed but aware — light meditation, gentle creativity, and stress reduction. A good starting point for newcomers.
Beta β
13 – 30 Hz Concentration · Analysis · Alertness
The dominant rhythm during active waking consciousness. Higher beta frequencies support focused analytical work, problem-solving, and sustained attention. Lower beta supports calm engagement.
Gamma γ
30 – 50 Hz Peak cognition · Learning · Binding
The fastest brainwave pattern. Associated with moments of insight, high-level information processing, and cross-brain neural binding. Notably elevated in experienced meditators.
