Not sure why, but I’ve always found it easier to fall asleep when there’s a party going on in the next room. There’s something about the fountain of sound when lots of people are chatting away at the same time. Hence, Soap.
Soap lets you choose the number of voices you want to hear simultaneously (big party / small party), and can give you varying durations of stereo or mono voices ranging in tone from soothing to edgy.
Where do the voices come from? They come from late 50’s-to-early-60’s soap operas. Hence, ‘Soap’.
