The sounds, if you want the details
You came for a quieter hour. This is what is in the catalog.
Beats
Binaural beats need headphones. Two tones, one per ear. You hear the difference. Sleep 3 Hz, Deep Sleep 0.25 Hz, Meditation 4 Hz, Relaxation 9 Hz, Creativity 10 Hz, Focus 16 Hz, High Alert 24 Hz, Narrow Focus 40 Hz.
Noise
White, pink, brown, green. A mask for a loud room or for tinnitus perception. Speakers are fine.
Tones
Solfeggio such as Clarity (852 Hz). One pitch. An anchor when the mind loops.
Ambient
Campfire. Jungle rain. Steady, no vocal, no music.
A session
Pick from Beats, Noise, Tones, or Ambient. One sound at a time. Set the carrier (150 to 480 Hz). The beat stays the same. Timer is 1 minute to 5 hours, starts at 30. Save a preset. Headphones for beats. Then close the phone.
