Binaural Beats

Pure tones played together interfere with each other when they are close in pitch but not identical. When each tone is sent to a different ear, there will not be any physical interaction between the waves, yet your brain still creates an interference inside your head: the so-called binaural beat. In order to create a binaural beat, each ear must receive its dedicated signal. Therefore, binaural beats only work through headphones.

Most binaural beat generators on the Internet use two carriers: one for each ear. We use 10 of them instead, creating the most complex beating patterns ever produced online! We also use the purest sine waves generated from a professional test tone generator, ensuring the clearest and deepest beats.

Activating the motion feature ever-changes the beating patterns, entraining various brainwaves frequencies one after the other. Have a try!

A word to the purist here. This binaural beat generator offers ten carrier frequencies, but humans only have two ears! Therefore, carriers on this generator will produce amplitude-modulated beating patterns inside each ear canal. This is not necessarily a bad thing, as it increases the perception of the overall beating pattern, and helps our brain catch up with the binaural beat. This explains why this generator produces stronger beats than any other available. If you are looking for a pure binaural beat generator instead - one without any intra-aural interference but a weaker stimulus - try our Harmonic Binaural Beat Generator; its carriers have been set to distant frequencies, in order to suppress any amplitude modulation between carriers.

Brain Waves (brainwaves) Entrainment

Brainwaves are electrical activity patterns caused by the neurons of the brain communicating with each other. Brainwaves can be detected using sensitive medical equipment such as an EEG. They provide an indication of the mental state of an individual.

Brainwaves are divided into four main categories: the Delta waves, when deep sleep occurs; the Theta waves, associated with a state of somnolence and reduced consciousness; the Alpha waves, when we are in a state of physical and mental relaxation; and the Beta waves, emitted when we are consciously alert, or when we feel agitated or tense.

Brainwave frequencies are in the range of 0.1 to 4 (Delta), 4 to 7 (Theta), 7 to 13 (Alpha) and 13 to 60 (Beta) cycles per second (Hz).

Brainwave entrainement (or synchronization), aims to cause our brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state. This can be used, for example, to induce sleep. This page uses binaural beats as auditory stimuli.

  Thank you so much for making my life easier! Love this website!

  The focused setting is wonderful! I used to be trapped in an endless loop of web surfing and constant distractions, just glancing at my homework from time to time, but now I can actually sit down and write several pages of an essay without tabbing away or losing my focus.

  The 2Hz deep sleep setting absolutely lives up to it's name! 10 minutes of it and I can't keep my eyes open!

  Should I put fear on in the background while playing spooky video games?

  I used to not be ale to sleep due to hyperactivity. Not any more!!!

  Wow, the 8 hz relaxation setting literally has a tranquilizing effect. I felt like mush (in a good way ;). At first it sounds like the opposite of relaxing, but stick with it.

  Using the focused setting, I have completely changed my study/homework habits. My ADHD self was able to finish 4 assignments in one sitting! Thank you Dr. Stephane!!!

  This was a WOW experience for me. Before I found this website, all I could focus on was... you guessed, nothing. This website really helped me, thanks for the wonderful sounds.

  This allows me to focus on my work at night; normally, I would be a walking zombie then.

  Now I understand why I used to go to sleep with Pink Floyd's 'Welcome to the machine', an almost 2 Hz binaural beat.

  This is an odd sensation - but fun. It made me laugh - it's like a soothing massage in your head. Matt

  I used to get frequent headaches. At first it was because I wasn't drinking enough water. Then they started coming back. A great friend introduced me to this site and this sound. Now that I listen to this sound, I rarely have headaches. Thank you!!! <3 <3 <3

  Peaceful joyful

  Lately I have been getting a roaring sound coming from the back of my head. It sounds a lot like this, but listening to this helps a lot.

  I like to use this sound to help me focus on the more emergent work. It keeps me calm but focused so when people come by every 5 minutes asking "is it done yet?" I won't rip their head off.

  It helped me so much with my sleeping problem. Thank you so much!

  I admit that I do not know much about brainwaves and can be swayed by suggestion (ah, the fickle subconscious), but since using this machine and sort of hiding the noise with other sounds or my own music so it is not so obvious to me, it has helped me get through my email correspondences and other online tasks with the focus that I need. Thank you so much for making this!

  I had been having some trouble focusing, but listening to this noise helped me a lot! Also, if you listen closely, it sometimes sounds like music. :P -Some random girl that ended up here ^w^

  I like to listen to this on low volume whilst listening to radio at the same time. It keeps me relaxed and helps me find things more funny, strangely enough. ¯\(ツ)/¯

  (Pair it with Deserted) You step into your dreams, but something is wrong. A low hum haunts you. It comes from everywhere, and it keeps getting closer and closer. You try to escape by waking up, but then you realize - you can't.

  This with sweeping pink noise in the background is my favorite noise to listen to at work. It helps keep me alert and focused on the task and even blocks out the noise from chatty coworkers. Since I discovered this combination, work days seem to pass by quicker and I get much more work done.

  Thin apartment floors + downstairs neighbor who likes bass-heavy music = THANK YOU for the binaural beat generator. Not only are these beats relaxing and pleasant to listen to, the deeper tones completely block out the bass from my neighbor's stereo. We used to argue constantly over the noise but now he can listen to his music, I can listen to my beats and everyone's happy.


  Nice way to stay focused while learning.

  This makes me feel great. I get great sleep, can relax, and just feel good over all! :D

  It really helped me stay focused to write my huge essay!

  I used the Alpha stage to think and meditate and used the Napoleon Hill technique of a council meeting. Whereby I imagine a group of my peers alive or dead, anyone that I want to think of. I am The chairman, I set the stage by asking the question. I imagine what they would say to me and advise in answer to my question of the night. It takes on a life of its own and will shock you. It's real!

  I use this to focus while I do work.

  On the nights where sleep eludes me, the 2Hz deep sleep binaural noise works wonders.

  This with sweeping white noise gives me the PERFECT non-drowsy, creative focus for art, reading, and writing. Not to mention helping with depression and anxiety. THANK YOU SO MUCH MR. PIGEON!!

  ← Handsfree brain massage - bye bye headache

  I use this to focus while I do work.

  I really love the brainwaves gens and the focus setting really helps me stay attuned, but for some reason my girlfriend can't stand it. I guess it's not for everyone but it sure is for me!

  This is so much better than caffeine! Keeps me alert, makes it easy to focus, and no crash later. Thanks!

  I have both Multiple Sclerosis & Lupus, as well as Fibronyalgia. Chronic pain makes it impossible to rest, let alone sleep. The low tones of the binaural beats, animated, help take away the pain, and cause me to fall asleep. Thank you so much for creating this site, and free as well! Life often felt like a living hell before I found these wonderful 'beats'! =)

  Perfect concentration

  ← Native War Beat. Helps me prepare for the day ahead.

  I thought that this would give me a big headache, but that did not happen! Really clears my over-active mind up.

  Makes me feel focused and creative and everything is smooth

  I like to layer this over the sweep noise generator set to "animate". The constant under tone combined with the airy sweep noise is relaxing and helps me focus on tedious reading!

  ← Combined some Fantasy and Focus for some creative writing and art beats.

  This sound, though strange and a little creepy, really makes me think. But, it can give major headaches, be careful...

  This has literally been a lifesaver. I'm ADD and sometimes, no matter how much I want to settle to my work, I can't. Like there's cotton stuffed up the back of my skull keeping my analytical and creative sections of my brain from functioning. With the binaural beta waves, I finally feel my mind relax, the cotton easing out, and I'm able to WORK. I'm a little bit teary-eyed, THANK YOU SO MUCH.

  When you have 6 year old nese to take care of a little meditation helps.

  I don't know what it is about low notes to me, but they always help me meditate and can lull me to sleep.



  Please make this into an app: wish I could sleep with it, but can't leave my laptop screen on. This is so amazing and relaxing!

  It's calming and helps me clear my mind for studying.

  Heartbeat in your head.

Each slider controls a particular frequency. Adjust sliders to induce a particular mental state. Mixing adjacent sliders works best.


Our brainwave generator specifically outputs frequencies that replicate the cycles of brain waves. By syncing up your brain with these frequencies, your state of consciousness will be altered.

Because of the strong and repetitive pulsating rhythms, people who are prone to seizures or epilepsy should not use our brainwave generator. Children and pregnant women should also use caution when considering using brainwave entrainment.
