Binaural beats, or binaural tones, are auditory processing artifacts, or apparent sounds, caused by specific physical stimuli. The brain produces a phenomenon resulting in low-frequency pulsations in the amplitude and sound localization of a perceived sound when two tones at slightly different frequencies are presented separately, one to each of a subject's ears, using stereo headphones. A beating tone will be perceived, as if the two tones mixed naturally, out of the brain. The frequencies of the tones must be below 1,000 hertz for the beating to be noticeable. The difference between the two frequencies must be small (less than or equal to 30 Hz) for the effect to occur; otherwise, the two tones will be heard separately, and no beat will be perceived.
This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.
Binaural beats are of interest to neurophysiologists investigating the sense of hearing. Binaural beats reportedly influence the brain in more subtle ways through the entrainment of brainwaves and have been claimed to reduce anxiety, variety of mental and emotional conditions and to provide other health benefits such as control over pain.
Deskripsi of Binaural beats therapy
Binaural beats stimulates your brain by sending special auditory artifacts directly into your headphones to produce subtle changes in behavior though entraiment of brainwaves frequency. This app can help induce relaxation, creativity and many other desirable mental states.*WARNING*
Binaural beats are very powerful and new presets must be experienced carefully, in a safe environment. But rest assured, I have been using binaural tones for a few years now with great success and without any concern.
This application is 100% free and open source as a way to give back and create a large community of users, enjoy!
*Getting involved*
Anyone can participate and make this app better, I am looking for people to help on graphics, sounds, tone presets, documentation, video tutorial, ideas as well as developers!

Now automatically pause and resume if a phone call arrives.
This is why PHONE_STATE permissions are required. The app doesn't have internet access so there's no chance of sniffing numbers. I cannot reply to review comments because there is no way to do it, so please email me any feedback. I reply to all well-written feedback
