This android app is designed to play sequences of sound to deactivate the brain, to slow down the heart beat, to reduce breathing rate and eventually to induce the user to sleep. The app can play music and other sound pieces such as birds singing.
The app will play sound or music pieces stored in the subdirectory named ‘sleepdreaming” in the “Music” directory of the phone. However, if this directory is empty, the app will play one of six sound pieces coming with the app. The user can select a sound or music pieces from the dropdown menu.
The app has three functions to choose from. One is to modulate the volume with a harmonic function to attract the user's attention. Another one is to change the pitch of the sound played to deliver the slow-down effects to the user. A third is to play the sound pieces with intervals to let the user relax.
The user can test the sound without selecting other parameters. But the listener must check at least one of the three functions (checkboxes) and select a length of time in order to play. During playing, the remaining cyclers are displayed on the face of the button.
