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 or the buttons "Set L and Set R" which allow you to enter the exact amount you want.

Use values with two decimal points (eg 125.65) or choose one of the built in presets.
The sounds are produced in real time they are not pre-recorded sounds. This enables to play them without interruption.
The pure sine-wave sounds are processed in real time natively by your mobile device with Pure Data (libpd).

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.
