White Noise Generator for iPhone and iPod touch
The ONLY White Noise Generator that that uses
mathematical sound algorithms to generate any color of
noise. All sounds are generated dynamically! 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 sound shutoff timer. The shutoff timer can be set to a specific time or countdown. 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
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) 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.
- True White Noise Generator that generates all sounds dynamically using sound algorithms
- Generate Red/Brown, Pink, White, Blue, Violet/Purple, and all colors in between.
- Includes Low and High Pass filter
- Sound graph of generated wave form audio
- Timer allows for storm sounds to be turned off automatically saving battery life.
- Audio fader lowers volume during last minute of timer so you won't wake up abruptly.
- Application exit will quit the application to save even more battery life.
- All timer features are optional and all timer settings remembered.
White Noise Generator is available for your iPhone or iPod Touch at the iTunes App Store.
