Serenity

Plays sound in the background, to help you to relax, or to drown out distractions such as construction or traffic. Can be useful when you need something less intrusive than background music, for example when sleeping, studying, or listening to an audiobook.



Features:
Volume control for app
Volume control for each sound
Sleep Timer
Custom Sounds (mp3;ogg;wav)
Background Playback
Multiple simultaneous sounds (e.g. Bird Song + Fire + Stream)
Looping fix*

*Some android devices refuse to loop gaplessly using the default implementation. Enabling the looping fix should correct this if necessary. However, you may have to experiment with its value for it to work correctly. It should be set high enough to remove the gap and no higher.
