This is an application to aid with relaxation, sleep and meditation. You can select from a wide variety of relaxing sounds and ambient noise for your phone to play to you.
An advert free, paid version is also available as "Lullaby Pro" for the minimum Android Market fee. The pro version also supports older Android versions back to 1.6.
Most sleep machine apps on the market simply consist of a single recording wrapped up in an app.
Where Lullaby differs, each soundscape is dynamically generated, it never repeats, never loops, never ends. I use primitive animal/physics behaviors to generate multi layered audio, and a number of psycho-acoustic methods to set a believable sound stage. Great care has been spent to provide seamless, click free audio playback, to create soundscapes you can really explore in your mind's eye.
This allows the app to be relatively small and still have a large choice of audio, while preventing loops and patterns emerging from the sound scape, disturbing relaxation. Every time you listen to Lullaby, you will get a unique sound experience.
Rain, sea and lake waves, wind, river and fire side sounds.
IEEE standard White\pink\brown\violet\blue noise.
Nigtingale\thrush\loon\duck\cuckoo and crow calls.
Farmyard animals, sheep, pigs, cows, dogs.
Over 30 calming soundscapes.
Option to automatically fade out soundscapes to prevent disturbance of REM sleep.
Precision volume control allows you to set volume much lower than other apps.
Lullaby delivers stereo output, using phone speakers will seriously degrade your listening experience.
Many thanks for all the lovely comments and ad-clicks I've received. Its a great encouragement to keep improving Lullaby. If there's a soundscape you'd like me to add, you can mail me from within the app, or leave a review with your suggestion.
I am happy for Lullaby to be used to provide ambient audio in such venues as pubs, restaurants and shops. Please purchase a copy of Lullaby Pro if you wish to use it for this purpose, you will receive lifetime upgrades and much more rigorous testing than the free version.
