Binaural Beats are when two different tones usually less than a 40 Hz difference difference between them are played, one in each ear, at the same time. An auditory illusion is created and the individual hears a third tone in their mind, with that third tone being the "binaural beat".
@raleighing Thank you very much for the feedback. I have fixed that issue and pushed a new version for approval. V1.0.1 will not stop playing audio when the phone goes to sleep.
