Ambi Pro is an ambient noise generator designed to aid relaxation and concentration by masking extraneous noise.

Unlike many apps that use looped audio recordings, Ambi generates a unique blend of constantly changing noise algorithmically that never repeats.

The mix can be altered to taste by manually dragging the white sphere, or randomised automatically by selecting 'motion'.

Digital reverb is available for an increased sense of depth, while the 8 band graphic equaliser lets you sculpt the audio output to your taste.

There is a timer to automatically switch off the sound after a given time, and presets to save your favourite eq choices.
