Ambi is an algorithmic noise generator designed to aid relaxation and concentration by masking extraneous background noise. Unlike many apps that use repetitive audio loops, Ambi generates an ever changing mix of white, brown, pink and water noise that is always unique. The mix can be altered to taste by manually dragging the sphere on the mix screen, or randomised automatically by enabling motion. Reverb can be added to increased the sense of depth, while the 8 band graphic equaliser allows you sculpt the audio to your taste. There is the option, via an in-app purchase, to access the built in timer and user presets creation, to save your favourite eq, reverb and motion settings.
