NeuroSounds unlocks your mind's potential by using Binaural Beats - an auditory phenomenon where slightly different frequencies played in each ear create a perceived third, rhythmic beat. Your brain naturally aligns its electrical activity to this frequency - a process called “Neural Entrainment”. This gently encourages your brainwaves to shift towards desired states, supporting your cognitive and emotional well-being without conscious effort.
What's New In This Version
-
Optimised Frequency & Playback Settings for Effectiveness
-
Narrowed Audio Spectrum
The previous version was a bit ambitious in offering a carrier range up to 1000 Hz, while this update narrows the band down to the most effective range. This change directly reflects research on human auditory brainstem responses showing that neural entrainment efficiency peaks at specific ranges, while some frequencies can actually result in diminished neural effects.
-
Expanded Selectable Main Frequency
The previous version attempted to isolate the main frequency to different mental states, although this doesn't make a difference to the effectiveness. So this version allows you to pick a main frequency that feels most comfortable.
-
Removed Random Playback
The previous version's 'Random Playback' had actually been counter-effective. In research, a frequency change outside of a specific threshold, actually results in Neural Phase Disruption — a process that breaks the synchronizing of neurons firing within the Superior Olivary Complex (Brainstem), causing you to lose all progress.
Instead, all the playback in this version will continuously randomize the frequency within the safe threshold to maintain brain synchronicity. This continuous randomization prevents another problem of Sensory Adaptation - where constant, unchanging audio signals naturally decrease neural responsiveness over time.
-
Replaced Playback Duration with Entrainment Depth
Neural Entrainment is not an instant switch, but a gradual process. The new 'Entrainment Depth' setting lets you choose how long to keep the playback going, depending on how out of sync you feel relative to the mental state you wish to achieve.
-
-
Introduced Mental Phase Presets
These presets offer quick access to carefully structured, multi-phase sequences to guide you through your required scenario.
-
Beta Mental State Split into Low, Mid, and High Beta States
The previous version had Beta as a single mental state. However, it actually spans quite a wide mental range — starting from Calm Concentration to High Stress. Splitting Beta into sub-phases allows for better control of your desired outcome, and to carefully handle the high-stress range

What are Binaural Beats & Neural Entrainment?
Research has shown that when two slightly different sound frequencies are played separately into each ear, the brainstem (specifically the Superior Olivary Complex), processes a third perceived frequency, called the Binaural Beat.
As neurons begin firing in lockstep with this perceived frequency, your dominant brainwave activity naturally shifts to match it - a process called neural entrainment.
This phenomenon allows you to intentionally and effortlessly influence your mood and cognitive state through sound.
Mental State - Delta
Deep Sleep & Recovery
Somatic Regeneration & Restorative Sleep
Your mind is completely detached from waking consciousness while your body rests in profound stillness. Heart rate and breathing slow to their baseline as energy directs entirely toward tissue repair, cellular restoration, and physiological recovery without interruption from dreams or mental activity.
Use these frequencies when you need deep physical healing, total recovery from exhaustion, and restorative rest.

Mental State - Settings
Optimal Frequency Range
The outer ring highlights the frequency range that should be optimal for the main frequency. This should be used as a guide, and you should still choose a frequency that feels most comfortable to your mood.
Main Frequency Range
This interactive ring let's you choose the main frequency, which left and right frequencies will be anchored against. You should choose the main frequency that feels most comfortable, and matches your mood.
Binaural Intensity
This interactive ring, is the key setting for your neural entrainment to acheive the required mental state. You can choose between an emphasis to the left or the right, and intensity controls how deep into the mental state you would like to be.
White Noise & Entrainment Depth
'White Noise' is an extra feature included to help drown out distractive environmental sounds. This does reduce the effectiveness of the binaual neural entrainment, so you should use the minimum level required for your environment.
'Entrainment Depth' let's your choose between light, standard and deep, which affects the length of the playback duration. You choose this depending on how out of sync you feel relative to the mental state you wish to achieve.
Playback Effect
The 'Fixed' playback, contains the main frequency and binaural beat within the selected range. You would use this to shift your mental state to the selected outcome, and to remain in that phase.
The 'Sweep Up' playback, gradually shifts you from the start phase to the end phase of the selected mental state. You can use this when trying to shift up to the next mental state.
The 'Sweep Down' playback, gradually shifts you from the end phase to the start phase of the selected mental state. You can use this when trying to shift down to the next mental state.
Restore Defaults
Since the app does require a bit of experimentation, this feature allows you to easily restore the default settings. You can choose to restore the settings only for the selected mental state, or for all the mental states.
Mental States & Mental Presets Selector
This allows you to see and choose from all the mental states and the mental presets available in the app, in a single view. This makes it convenient to see where your current mood is in the range, and also which mental presets might be most helpful.
Mental Preset - Drift To Sleep
Benefits & Application
Ideal for bedtime routines, late-night restlessness, or recovering from sleep disruption, this preset transforms overactive night-time thoughts into physical heaviness and deep sleep. Place your device nearby, close your eyes, and let the acoustic progression ease you straight into undisturbed, high-quality rest.
Initial State
You should already be winding down for the evening, feeling relaxed and ready to drift off rather than buzzing with late-night energy.
Setup & Environment
Get tucked into bed with your bedroom lights dimmed or completely off, and your phone placed safely out of reach on the nightstand.
Important Note
Don't try to use this right after a heavy workout, a late cup of coffee, or a stressful work session. Give yourself at least 30 to 60 minutes to naturally decompress before hitting play.
The Journey
Engineered as a gentle, one-way descent into deep rest, this session is designed for night-time wind-down and insomnia relief. Starting at Mid Theta, the frequencies meet your mind in a state of quiet relaxation and gradually step down through the hypnagogic threshold into Mid Delta. By slowly decelerating neural firing, it helps quiet lingering mental chatter and effortlessly guides you into restorative slumber without returning you to an awake baseline.
Brain Chemistry & State
Transitioning from Theta down into slow-wave Delta suppresses thalamocortical arousal and down-regulates central nervous system activity. As high-frequency cortical chatter subsides, parasympathetic dominance takes over, triggering the release of melatonin and activating the brain’s glymphatic system to clear metabolic waste accumulated during waking hours.
Mental Preset - Meditative Cycle
Benefits & Application
Ideal for midday resets, stress relief, and mindfulness practice, this cycle helps dissolve mental tension, restore emotional equilibrium, and enhance intrinsic self-awareness. You exit the session with a centered, resilient mind, recharged with calm focus and ready to re-engage with your day.
Initial State
You should be in a generally calm or mildly restless headspace, ready to quiet your mind and turn inward.
Setup & Environment
Find a quiet, comfortable spot to sit or recline, close your eyes, and settle in where you won't be interrupted.
Important Note
If your mind is racing with acute stress or anxiety, don't jump straight here. Run the 'Calm Down From The Stress' preset first to bring your baseline down to a place where meditation actually works.
The Journey
The Meditative Cycle guides your focus inward, beginning in light Alpha relaxation before descending smoothly into deep Theta meditation, then lifting you back into composed Alpha clarity. This gentle downward and upward curve allows your mind to slip effortlessly past daily mental chatter, experience profound stillness, and return fully refreshed without feeling groggy.
Brain Chemistry & State
As your brainwaves transition from Alpha to Theta, neural activity slows into low-frequency synchronization. This shift calms the nervous system, decreases baseline cortisol levels, and promotes the release of serotonin and endorphins. Synaptic signaling shifts away from active external monitoring, encouraging deep autonomic recovery and reduced sympathetic stress responses.
Mental Preset - Cognitive Cycle
Benefits & Application
Designed for long study sessions, complex problem solving, and intensive project execution, this cycle prevents burnout by matching your body’s natural BRAC physiological rhythm. It maximizes focused output while building in structured cognitive recovery, leaving you sharp, productive, and mentally sustainable throughout the day.
Initial State
You should be feeling alert and awake, sitting at your normal operational baseline, ready to tackle structured work.
Setup & Environment
Be seated upright at your desk or workspace with your tasks open and everything you need within arm's reach.
Important Note
Avoid starting this when you are completely wiped out or severely sleep-deprived. Audio entrainment can guide your focus, but it can't manufacture cellular energy out of thin air.
The Journey
Engineered around the brain’s natural Basic Rest-Activity Cycle (BRAC), featuring a 90-minute ultradian cognitive peak followed by a 30-minute recovery period—the Cognitive Cycle guides you into a state of sustained high performance. Starting in steady Low Beta, the session ramps up into focused Mid Beta for an extended period of deep work, then descends through Low Beta into restorative Alpha relaxation before gently lifting back to Low Beta to complete the 120-minute loop.
Brain Chemistry & State
Sustained Mid Beta activity stimulates executive prefrontal networks, enhancing norepinephrine and dopamine signaling to elevate alertness, working memory, and task engagement. As the cycle transitions down into Alpha, the brain steps back from active information processing, allowing neural metabolic waste to clear, Adenosine Triphosphate (ATP) energy reserves to replenish, and neurotransmitter sensitivity to reset for the next cycle.
Mental Preset - Calm Down From The Stress
Benefits & Application
Ideal for high-stress work moments, post-confrontation resets, or easing intense overthinking, this preset brings you back to a state of calm productivity. It clears the mental static and physical tightness caused by high stress, restoring emotional control, objective decision-making, and composed focus so you can navigate the rest of your day with ease.
Initial State
You should be feeling overwhelmed, anxious, or caught in mental overdrive with your sympathetic nervous system stuck in high gear.
Setup & Environment
Sit back wherever you are, at your desk, on a couch, or in a quiet corner, loosen any tight clothing, rest your hands in your lap, and close your eyes.
Important Note
This is your emergency brake for high-stress moments. You don't need any special prep, but make sure to pair it with slow, deep exhales to help your body actually accept the downshift.
The Journey
Designed as a direct, one-way transition rather than a recurring loop, this session steps in when you are feeling overwhelmed, overstimulated, or anxious. Starting at High Beta to match your elevated mental state, the frequencies steadily guide your brainwaves down into Mid Beta. By meeting your mind where it is and gradually lowering the tempo, Calm Down From The Stress helps you step back from acute tension without dumping you into drowsiness.
Brain Chemistry & State
High Beta is linked to sympathetic nervous system dominance, hyper-arousal, and elevated cortisol and adrenaline. Steadying the brain down into Mid Beta suppresses excess central nervous system agitation and down-regulates fight-or-flight signaling. As neural firing rates settle into a controlled rhythm, excess glutamate activity subsides, paving the way for GABA (gamma-aminobutyric acid), the brain’s primary inhibitory neurotransmitter, to restore neurochemical balance.
Mental Preset - Push Through The Stress
Benefits & Application
Ideal for high-pressure deadlines, emergency troubleshooting, or critical rapid-response scenarios, this preset channels nervous energy into high-throughput execution. It transforms overwhelming stress into hyper-focused insight, rapid pattern recognition, and decisive action, allowing you to power through critical bottlenecks when failure is not an option.
Initial State
You should be feeling sluggish, stuck in brain fog, or battling low-motivation resistance when you actually need to get things done.
Setup & Environment
Plant yourself at your desk with your specific task sitting right in front of you, ready to roll the second the audio starts building your momentum.
Important Note
Don't use this late at night when your body naturally wants to rest, and skip it if your sluggishness is actually coming from genuine physical exhaustion or illness.
The Journey
Designed for high-stakes situations that require absolute, uncompromising focus, this one-way transition meets your brain at High Beta and rapidly accelerates your neural state into Gamma. Because of the intense cognitive demand and eventual brain fatigue associated with driving high-frequency synchronization, Push Through The Stress should be used sparingly, reserved for short, critical windows where you must perform at your absolute peak despite ambient stress.
Brain Chemistry & State
Accelerating into Gamma frequencies triggers widespread cortical binding, the simultaneous synchronization of separate brain regions. This high-frequency activity drives high rates of dopamine, acetylcholine, and norepinephrine release across prefrontal networks, maxing out sensory processing speed, working memory capacity, and neural signal integration. This intense state relies heavily on cellular energy, rapidly depleting Adenosine Triphosphate (ATP) reserves in exchange for temporary peak cognitive output.
Mental Preset - Hyper Focus Cycle
Benefits & Application
Designed for long-form deep work, complex architecture, and intensive project execution, this cycle transforms a multi-hour focus session into a structured, self-sustaining loop. Because it provides sustained productivity across both its ascent and descent phases while demanding heavy metabolic energy during the Gamma peak, Hyper Focus Cycle should be used strategically, no more than once or twice a day, delivering maximum output while safeguarding long-term stamina.
Initial State
You should be primed, caffeinated (if that's your thing), and sitting upright with a clear intention to dive deep into a major project.
Setup & Environment
Clear your digital and physical desk, mute your notifications, grab a glass of water, and make sure your schedule is completely clear for the next three hours.
Important Note
Never jump straight into this when you are emotionally agitated, highly stressed, or coming right off intense physical exertion. Because this cycle includes an essential recovery arc built into its 3-hour duration, make sure you can commit to letting the full session run its course rather than cutting it short.
The Journey
Engineered as an expansive high-performance protocol, the Hyper Focus Cycle uses targeted neuro-acoustic entrainment to ride a continuous wave of active productivity. Starting in Low Beta, the session executes an unhurried climb into ultra-high Gamma synchronization for a peak cognitive sprint. As the frequencies descend through High and Mid Beta, high-throughput execution continues uninterrupted, allowing you to capitalize on sustained flow before the cycle gradually downshifts through Alpha into a restorative Theta lock, finally bringing you back to Low Beta baseline.
Brain Chemistry & State
Ascending into Gamma triggers widespread cross-cortical binding, surging dopamine, acetylcholine, and norepinephrine to unlock peak working memory. As the session downshifts into Mid Beta, active prefrontal engagement remains high while neural strain eases. Once the descent reaches Theta, sympathetic arousal suppresses, allowing cellular Adenosine Triphosphate (ATP) energy reserves to replenish and metabolic waste to clear, preventing a cognitive crash while preserving neurochemical balance.

The Story Behind
Sitting at a cafe and reading a book is a simple pleasure many of us enjoy. However, it's completely dependent on your surroundings, and you're likely to encounter noise distractions—something I was experiencing firsthand. This is where the story of this app begins.
Most of us would simply play some music to drown out the noise. This didn't always work for me, though, because I'd get caught up in the music and still lose focus on my book.
So, I started looking into creating a white noise generator—a constant, random buzz that could cancel out the sounds around me without being distracting. This led me to learn about other types of sound like Pink Noise and Brown Noise.
As I delved into the scientific research to find the ideal noise for canceling distractions, I stumbled upon Binaural Beats. This introduced me to a whole new concept I had never heard of before.
From there, the NeuroSounds app was born. It became an app that wasn't just about drowning out distractions, but about actively tuning your brain into different mental states to match the task you have on hand.
