About this app

With this app you can easily generate pure waves that will stimulate your concentration, meditation or relaxation.


Very Important
• Use headphones for a better sound experience

• Don't use this app while driving or operating heavy machinery.

• Take care of your hearing, is not necessary to hear these sounds at high volume.


You can generate and save your own frequencies using two independent oscillators, controlled by two horizontal bars, with fine adjust buttons or directly by input the desired value you want (tap the left or right frequency value to open the input dialog).
You can use values with two decimal points (eg 125.65).

The sounds are produced in real time, they are not pre-recorded sounds. This enables to play them without interruption as long you want.

How it works
Binaural beats, or binaural tones, are auditory processing artifacts, or apparent sounds, caused by specific physical stimuli.
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.

To experience the binaural beats perception, it is best to listen to this file with headphones on moderate to weak volume – the sound should be easily heard, but not loud. Note that the sound appears to pulsate only when heard through both earphones.

Take care of your hearing, is not necessary to hear these sounds at high volume.
The bottom slide bar controls the volume, but it is independent of your device's volume, so if there is no sound or it's too high, also set your device's volume to balance the sound.

Also Important
Latest Android versions, are evolving to manage system recourses and automatically slow down the cpu usage for optimize resources.
The real time audio synthesis, like we use in our apps is a very sensitive process when the OS is trying to stop or decrease cpu usage for this main thread.

If you have some issue playing the audio, please follow the instructions in this link:
