Floating Clouds is a 40-minute NeuroSync Pro® audiovisual session in the Relaxation category for people who enjoy imagery and want to drift away from everyday concerns without using a formal sleep protocol. The protocol combines rhythmic audio, optional light stimulation and music across five phases.
This Relaxation version of Floating Clouds differs from the Sleep session with the same name. It descends to 6 Hz but includes a clear return to 10 Hz, framing the experience as temporary drifting followed by reorientation.
What relaxation means neurocognitively
Relaxation is not a single brainwave or a state produced by one switch. It emerges from interactions among attention, breathing, muscle tension, expectations, perceived safety, environment and autonomic regulation. People may become physically calmer while thoughts remain active, or experience mental space without becoming sleepy.
A mind machine cannot directly measure or guarantee these processes. Its most defensible function is to provide a predictable sensory context in which someone can disengage attention from ongoing demands and deliberately practise restful behaviour.
Brainwave entrainment and the frequency-following response
Brainwave entrainment uses periodic auditory stimuli, including isochronic and monaural modulation, with optional rhythmic light. The frequency-following response describes how neural activity may respond to repeated input under some conditions. It does not mean that the entire brain exactly adopts the selected frequency.
Slower pacing around 6–10 Hz is often linked to alpha and theta terminology. These band names are descriptive EEG conventions. The external pulse is not an EEG measurement and does not prove that relaxation, recovery, trance or meditation has been achieved.
Research on brainwave entrainment and psychological outcomes is mixed and methodologically diverse. The protocol is therefore described here as wellness and attentional support, not as a proven treatment.
Why music, light and slow transitions are combined
Calm music can influence expectations, breathing pace, emotional meaning and time perception. Effects depend strongly on preference and context. A track that calms one user may feel emotional or distracting to another.
All phases use sine-shaped pulses with gradual transitions. The named colours are aesthetic design choices, not chromotherapy or medical light treatment. Greater brightness is not automatically more effective.

Analysis of the five phases
Phase 1: 5 minutes at 10 Hz
The opening phase marks the transition from daily activity to intentional rest. It provides orientation without forcing relaxation.
Technically, this phase uses isochronic, a sine pulse, Ambient at 50%, soft turquoise RGB light at 40 → 70% and white LEDs at 10 → 20%. The hertz value describes external stimulation, not measured brain activity.
Phase 2: 8 minutes at 10 → 8 Hz
This phase uses the design intention “Soften”. The combination of rhythm, music, light and expectation may support relaxation, but it does not prove a specific brain state.
Technically, this phase uses isochronic, a sine pulse, Soft Soundscapes at 45%, sky blue RGB light at 70 → 90% and white LEDs at 20 → 35%. The hertz value describes external stimulation, not measured brain activity.
Phase 3: 10 minutes at 8 → 6 Hz
This phase uses the design intention “Float”. The combination of rhythm, music, light and expectation may support relaxation, but it does not prove a specific brain state.
Technically, this phase uses isochronic + monaural, a sine pulse, Cinematic Ambient at 40%, light lavender RGB light at 90 → 100% and white LEDs at 35 → 45%. The hertz value describes external stimulation, not measured brain activity.
Phase 4: 12 minutes at 6 Hz
This phase uses the design intention “Deep relaxation”. The combination of rhythm, music, light and expectation may support relaxation, but it does not prove a specific brain state.
Technically, this phase uses isochronic + monaural, a sine pulse, Theta Soundscape at 35%, cloud white RGB light at 100 → 85% and white LEDs at 45 → 50%. The hertz value describes external stimulation, not measured brain activity.
Phase 5: 5 minutes at 6 → 10 Hz
The closing phase raises the pacing and reduces sensory load so that reorientation to the environment is gradual.
Technically, this phase uses isochronic, a sine pulse, Ambient at 25%, gold blue RGB light at 85 → 50% and white LEDs at 50 → 20%. The hertz value describes external stimulation, not measured brain activity.
Practical use
Use a simple image such as clouds moving across a wide sky. Let thoughts pass without needing to remove them. If imagery becomes uncomfortable or dissociative, open the eyes and orient to the room.
Evaluate the session with simple questions: did subjective tension decrease, did breathing become easier, did unnecessary muscle effort reduce and could you function appropriately afterwards? A striking single experience is less informative than a consistent pattern across repeated use.
Begin below the programmed maximum volume and light intensity. Audio-only is a valid option when light feels uncomfortable, activating or overstimulating.
Floating Clouds can be used as an audio session with the NeuroSync Pro Personal Edition mind machine. Professionals can adjust parameters in the Therapeutic Audio Edition. The audiovisual structure is designed for the Therapeutic Audio+Light Edition. Explore all editions on the NeuroSync Pro homepage.
Safety and important limits
NeuroSync Pro® is not a medical device. Floating Clouds does not diagnose, treat, cure or prevent anxiety disorders, burnout, trauma, chronic stress, insomnia, pain disorders or any other condition. Relaxation should not be forced, and results vary between individuals.
Do not use rhythmic light with photosensitive epilepsy, a seizure disorder or unexplained loss of consciousness without medical clearance. Never use the session while driving, cycling, operating machinery or performing another safety-critical activity. Stop if headache, nausea, panic, agitation, derealisation or dissociation occurs.
Frequently asked questions
Does Floating Clouds guarantee deep relaxation?
No. The session provides a structured context, but responses depend on the person, environment, expectations and current load.
Does the frequency mean my brain adopts exactly the same rhythm?
No. The number describes external audio and light modulation. Only EEG measures brain activity, which consists of multiple simultaneous patterns.
Can I use audio only?
Yes. Choose the least intensive configuration that remains comfortable and practical.
Can I use the session before sleep?
Yes, if it feels personally calming, but most protocols deliberately return to 10 Hz and are not treatments for insomnia.
When is professional support important?
Professional support is important for persistent anxiety, severe sleep problems, trauma symptoms, unexplained pain, marked functional decline or thoughts of self-harm.
