White Noise Generator

iOS iPhone

The ONLY White Noise Generator that uses mathematical sound algorithms to generate any noise color. Just look at the app size which is less than 200k! Popular uses for White Noise Generators include sleep aids, enhancing privacy, blocking distractions, masking tinnitus, configuring audio equipment, soothing migraines, and more.

The sounds that can be generated are red/brown, pink, white, blue, violet/purple, and all colors in between. Includes low and high pass filters, sound wave graph, and multiple sound shutoff timers and alarms. Timers can be set to a specific time or countdown specified number of minutes. Timer options include volume fader during last minute and application exit to save battery life.

White noise is a random signal with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency. White noise draws its name from white light in which the power spectral density of the light is distributed over the visible band in such a way that the eye's three color receptors (cones) are approximately equally stimulated.

Red Noise, also called Brown noise, refers to a power density which decreases 6 dB per octave with increasing frequency (density proportional to 1/f 2)[2] over a frequency range which does not include DC (Direct Current).

Pink Noise has a frequency spectrum that is flat in logarithmic space; it has equal power in bands that are proportionally wide.

Blue Noise has a power density that increases 3 dB per octave with increasing frequency (density proportional to f ) over a finite frequency range.

Violet noise, also called purple noise, has a power density that increases by 6 dB per octave with increasing frequency.

Sound algorithms developed with the help of an auditory neuroscientist from Johns Hopkins University.

What's new

- Fixed an issue with sleep view on earlier iOS versions.

Version 5.1 added:

- New alarm setting to resume playing after selecting Snooze. Enable this feature from the settings screen.

- The alarm screen now displays the digital clock instead of a static image.

- Play Sound and Play Mix timer options have changed. With these two options, the chosen sound or mix will begin playing like normal at the specified time instead of bringing up the alarm screen. They no longer have a 1 hour time limit.

- Play Alarm and Play Music timer options have been renamed to Sound Alarm and Music Alarm, respectively. This change was made to distinguish between alarm and play functions.

- Fixed issue with images when emailing sounds

- Other minor improvements
