Generate custom color noises including brown, pink, white, blue, and violet. Customize noise further by using low and high cut filters. Simple modern interface remembers all settings for quick generation and utilizes advanced mathematical formulas to generate all audio waves. There are no audio files included in the application binary which keeps app size to a minimum and app performance to a maximum. What are benefits of listening to white noise? - Helps you sleep by blocking distractions - Pacifies fussy and crying babies - Relaxes and reduces stress - Increases focus while enhancing privacy - Soothes headaches and migraines - Masks tinnitus (ringing of the ears) What are the different sound colors? - White noise sounds similar to static of an analog TV or radio station that has stopped broadcasting. White noise has equal energy across all sound frequencies. - Brown noise sounds like a powerful waterfall. It has more energy at the lower frequencies and if you have a good speaker system with a subwoofer you should be able to really feel it. - Pink noise's upper sound frequencies don't fall off as fast as they do with brown noise, so you'll get a little more punch. The most interesting thing about pink noise is it's found in almost all electronic devices (known as flicker noise) and even in biological systems. - Blue and violet noise are the opposites of pink and brown noise, respectively, and sound like spraying water from a garden hose. It has more energy at the higher frequencies which means more treble and less bass. - Curious to learn more about color noises?

Verdict

The call

The clearest difference is price: Noise Generator at Free against SoulTuner's $0.99. Noise Generator also leads on iOS requirement (15.0 vs 18.6). SoulTuner's advantage is ads (none vs shown) and update cadence (every 5 days vs fortnightly). On in-app purchases and device support there is nothing between them.
