Explore free, browser-based tools for working with pure tones, binaural beats, isochronic tones, colour noise and sound-based meditation.
The Bright Beings Academy sound generators allow you to listen to individual frequencies, combine selected tones and create simple sound sessions for meditation, reflection, focused listening or personal exploration.
People respond to sound in different ways. You may find certain tones soothing, grounding, stimulating or simply interesting to explore, but no particular response is guaranteed. Traditional, spiritual and symbolic associations are explained where relevant without presenting them as established scientific effects.
Each generator includes practical instructions and safety guidance. Begin at a low, comfortable volume, keep your first session short and stop if you experience discomfort.
Would you prefer a more guided introduction using voice, tuning forks, Tibetan singing bowls and energy chimes?
The collection includes a range of tools for exploring sound in different ways:
Pure tones, musical intervals, frequency combinations and harmonic drones.
Binaural beats, isochronic tones and amplitude-modulated sound.
Solfeggio tones, chakra tones, colour noise and other themed sound collections.
Timers, gentle fades, volume controls and selected session presets.
Clear instructions to help you understand and use each generator comfortably.
Safety guidance for volume, listening time, headphones and sound sensitivity.
Some tools draw upon traditional, spiritual, musical or symbolic systems. These associations are offered as frameworks for personal exploration rather than as scientifically proven effects.
Listening tip: Headphones are required to hear binaural beats as intended. Speakers can be used for pure tones, colour noise, isochronic tones and amplitude-modulated sound.
Pure tones
A pure tone is a single, steady frequency, such as 528 Hz.
It sounds like a smooth, continuous note or drone. Pure tones can be used as musical reference tones, as a background for meditation or as part of a personal sound practice.
Pure tones can be played through speakers or headphones. Because a continuous tone may feel intense at higher levels, begin quietly and adjust the volume gradually.
Binaural beats
A binaural beat is created by playing slightly different frequencies into each ear. For example, one ear might receive 400 Hz while the other receives 406 Hz.
When heard through stereo headphones, the listener may perceive a gentle rhythmic effect corresponding to the difference between the two frequencies. In this example, the difference is 6 Hz.
Binaural beats require stereo headphones to work as intended. They are often explored during meditation, relaxation or focused listening, although individual responses vary and specific mental or health effects are not guaranteed.
Isochronic tones
An isochronic tone is a single sound that pulses on and off at a regular rate.
The pulses are usually more noticeable than a binaural beat and may sound clear, rhythmic or repetitive. Headphones are not required, so isochronic tones can be played through speakers.
Some listeners find strong pulsing uncomfortable. Start with a short session at a low volume and stop if the sound causes tension, dizziness, headache or irritation.
Amplitude-modulated sound
Amplitude modulation gently raises and lowers the volume of a continuous tone at a chosen rate.
This creates a rhythmic effect without completely switching the sound on and off. It can be played through speakers or headphones and may feel smoother than an isochronic pulse.
A gentle listening reminder
There is no single sound type that is best for everyone. Choose the method that feels most comfortable, keep the volume modest and allow your own experience to guide the length of your session.
Choose a tool according to the type of sound you would like to explore. Each generator opens in your browser and includes its own controls, instructions and listening guidance.
Begin quietly, keep your first session short and notice how you respond. The descriptions below explain what each tool produces and the traditions or ideas it draws upon without promising a particular outcome.

Sound and Qi Gong
Explore how sound and Qi Gong can support one another
Discover the natural meeting point between sound, breath, movement and embodied awareness.
Headphones are required for binaural beats because each ear must receive a slightly different tone. Pure tones, isochronic tones, amplitude-modulated sounds and colour noise can be played through speakers or headphones.
There is no universal listening time. Begin with a short session of around five to ten minutes at a low, comfortable volume. Continue only while the sound feels comfortable, and take regular breaks during longer sessions.
Binaural beats use slightly different frequencies in the left and right ears, creating a perceived rhythmic difference when heard through stereo headphones.
Isochronic tones use a single sound that pulses on and off at a regular rate. They do not require headphones and can be played through speakers.
You may use them regularly if the volume remains comfortable and you experience no unwanted effects. Daily use is not necessary, and longer or more frequent sessions are not automatically more beneficial.
Stop listening if you experience headache, dizziness, nausea, irritation, increased ringing in the ears or any other discomfort.
Forty hertz falls within the gamma range of measured brain activity and is being studied in several areas of neuroscience.
Research is continuing, and a browser-based 40 Hz generator should not be treated as a clinical device, medical treatment or proven way to improve memory, concentration or brain health.
Neither tuning reference is inherently better for health or wellbeing.
A4 at 440 Hz is the widely used modern concert-pitch standard. Some listeners prefer music or tones tuned around 432 Hz, but claims that it has unique healing properties are not currently supported by dependable evidence. Choose according to your listening preference.
Resonant breathing is a slow, steady breathing practice, often explored at approximately five to six breaths per minute.
Slow breathing may influence heart-rate variability and can feel settling for some people, but the most comfortable pace varies. Do not strain, hold the breath or continue if you feel light-headed or uncomfortable.
No. The generators are provided for education, meditation and personal sound exploration. They are not medical devices and should not be used to diagnose, treat, cure or prevent a physical or mental-health condition.
Seek appropriate professional support for symptoms, distress or health concerns that require care.
The tone generators offer a free way to explore sound, but you may be ready for more structured guidance using your own voice and sound instruments.
Sound Healing Foundations is a six-week guided home-study mentorship exploring vocal toning, tuning forks, Tibetan singing bowls and energy chimes. The programme includes three one-to-one calls with Peter and is designed to help you create a safe, meaningful and sustainable personal sound practice.
Sound Healing Foundations is currently being developed. You can explore the programme and register your interest without payment or any obligation to enrol.
These sound generators are provided for education, meditation and personal sound exploration. They are not medical devices and are not intended to diagnose, treat, cure or prevent any physical or mental-health condition. They are not a substitute for professional medical advice, diagnosis or treatment.
Use the generators only in a safe setting. Do not listen while driving, cycling, operating machinery, crossing roads or doing anything else that requires your full attention.
Begin at a low, comfortable volume and keep your first session short. Listening risk is affected by both volume and duration, so take regular breaks and avoid increasing the volume to overpower background noise.
Stop listening immediately if you experience ear pain or pressure, dizziness, nausea, headache, agitation, disorientation, changes in hearing or increased ringing in the ears. Do not resume until the discomfort has fully settled. Seek appropriate medical or audiological advice if symptoms persist or return.
If you experience tinnitus, hyperacusis, hearing loss, migraines, epilepsy, seizures or sensitivity to rhythmic sound, approach these tools with additional care and seek professional guidance when uncertain. If you know that particular sounds, music or rhythms can trigger seizures, do not use rhythmic sound generators without advice from your clinician.
Binaural beats require stereo headphones to work as intended. The other generators can generally be played through speakers or headphones. Never use headphones in situations where you need to remain aware of your surroundings.
Your response to sound is personal.
Choose only tones and listening methods that feel comfortable, and stop whenever a practice does not feel right for you.
