Documentation

Everything you need to design, understand, and export precise tone stacks.

The sections below collect the articles that originally shipped with Vibryon. They walk through core concepts, popular reference tones, and a deep dive into binaural beat design.

What is a frequency generator?

Fundamentals

A frequency generator emits a stable tone measured in Hertz (Hz). Engineers use it to test signal chains, musicians for tuning, and sound explorers for meditation or binaural experiments. Vibryon embraces this utility by giving you immediate access to pure oscillators in your browser—no external software required.

How Vibryon works

Enter one or more frequencies, adjust each tone’s volume and stereo position, and press play. Every oscillator is scheduled to begin together, keeping stacks phase-locked. When you are satisfied, export a pristine WAV at 10, 30, or 60 seconds—all rendered offline so your workflow stays local.

Frequent questions

Does Vibryon run entirely in the browser?

Yes. It relies on the Web Audio API, so no plugins or installs are required.

How accurate are the generated tones?

Vibryon uses precise oscillators provided by your browser. Accuracy is suitable for creative and calibration tasks.

Can I download my mixes?

Absolutely. Export 10s, 30s, or 60s WAV files rendered offline as 16-bit PCM at 44.1 kHz.

Is Vibryon free?

Yes. Every feature is free to use directly in your browser.

Popular tones to explore

432 Hz

A musically warm tone popular for relaxed drones and layered instrument tuning.

528 Hz

Bright and clear—often used to sharpen focus or blend with 432 Hz for gentle beating.

639 Hz

Mid-range and smooth. Pair with lower tones to explore subtle interference patterns.

852 Hz

Bell-like and assertive. Keep levels comfortable when layering with mid and low tones.

1000 Hz

A clean reference tone for verifying signal paths and calibrating playback systems.

The science of sound

Pitch & loudness

Our ears perceive pitch primarily through frequency and loudness through amplitude. Context—duration, playback system, and environment—can dramatically change how a tone feels. Keeping these variables consistent is the best way to compare stacks.

Mixing pure tones

Combine sine waves to uncover beating patterns and spatial illusions. Vibryon gives you per-tone control to create precise interference or soothing drones without leaving your browser.

Run your own experiments

Keep Vibryon open while you adjust tone combinations. Export each iteration to compare mixes later or layer them in your DAW. Revisit saved mixes to understand how small shifts in frequency or pan reshape the perceived space.

Binaural beats guide

How the illusion works

Binaural beats are a perceptual rhythm your brain constructs when each ear receives a slightly different pure tone. Feed your left ear 432 Hz and your right ear 440 Hz; many listeners report sensing a soft 8 Hz pulsing—not in the air, but as an internal beat equal to the frequency difference. It is an auditory illusion born from how the brain integrates tiny inter-aural disparities.

You will only get the effect with stereo headphones, proper left/right separation, and modest offsets (typically under forty hertz). If you sum the signal to mono, the illusion disappears.

Why people experiment with them

Binaural beats live at the intersection of sound design, attention, and mood regulation. People experiment with them for relaxation, focus, creative drift, and sleep support. The experience is personal; use the range below as a starting point and adjust to taste.

  • 2 Hz (delta) — deep calm; use for wind-down or sleep onset.
  • 4 Hz (theta) — dreamlike drift; journaling, ideation, breath work.
  • 6 Hz (theta) — classic meditative sway; great for eyes-closed sessions.
  • 8 Hz (alpha) — relaxed focus; reading, soft work, mindful coding.
  • 10 Hz (alpha) — bright, present attention; creative flow.
  • 12–14 Hz (low-beta) — task engagement; time-boxed sprints.
  • 30–40 Hz (low gamma) — advanced; subtle for many listeners—test gently.

Carrier and gain guidelines

  • Use mid-range carriers: 200–600 Hz is comfortable and clear for most earbuds/headphones.
  • Keep carriers below ~1000 Hz for stronger binaural salience.
  • Try to keep left/right loudness matched; large level mismatches weaken the illusion.
  • Full pan left equals left-only, right equals right-only. Keep tones isolated for a clear beat.

Example: for an 8 Hz alpha beat you might set 432 Hz in the left ear and 440 Hz in the right, or 500 Hz and 508 Hz. Both produce the same beat— only the timbre shifts.

Workflow tips

  • Volume: start low. Perception improves with attention, not loudness.
  • Fade in/out over 10–30 seconds to prevent clicks or abrupt onsets.
  • Duration: 10–20 minutes for focus or meditation; longer sessions for sleep.
  • Add a gentle noise bed or ambience if you want to soften pure tones.
  • Ramp offsets gradually if you want to slide from one brainwave range to another.

Brainwave overview

Imagine the human brain as an orchestra of electrical rhythms. Brainwaves are the patterns of electrical activity produced by neurons firing in synchrony. Researchers divide waves into bands: delta, theta, alpha, beta, and gamma. Each corresponds to a unique mental state and has distinct effects on the mind and body.

Delta waves (0.5–4 Hz)

Delta waves are the slow bass notes of the brain’s symphony. They dominate deep, dreamless sleep where the body heals and regenerates. Enhancing delta activity can calm the stress response and support cellular repair.

Theta waves (4–8 Hz)

Theta is the creative dreamer—hovering between wakefulness and sleep. It accompanies meditation, visualization, and deep reflection. Many listeners reach for theta to spark ideation sessions or mindful breaks.

Alpha waves (8–12 Hz)

Alpha signals relaxed alertness. It is the neutral gear between focus and rest: eyes-closed breathing, journaling, soft concentration. Healthy alpha activity brings a sense of balance and calm clarity.

Beta waves (13–30 Hz)

Beta is the focused mind—conversation, analysis, decision-making. These faster rhythms drive task engagement and sustained thinking. High beta can also track with stress, so keep the experience comfortable.

Gamma waves (30+ Hz)

Gamma sits at the top of the spectrum and is associated with peak awareness and complex integration. Responses vary widely, so explore gently.
