Help

Type sequence of steps in the box.
Each line contains 3 whole numbers separated by commas:
- timestamp (in milliseconds)
- left channel frequency (hertz)
- right channel frequency (hertz)
Frequencies shift linearly between steps

Wear headphones and make sure that they're on with correct left/right
Binaural guide
The difference between left and right channel frequency is the binaural frequency experienced, e.g. 100 Hz left, 103 Hz right = 3 Hz binaural
- 1-4 Hz: Delta (Deep sleep)
- 4-8 Hz: Theta (Meditation/REM)
- 8-14 Hz: Alpha (Relaxation)
- 14-30 Hz: Beta (Focus/Energy)
- 30-100 Hz: Gamma (Maximum Awareness)
Experiment with which side has the higher frequency
