## What is Noise Generator?

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.

Directions:
Drag the Sound Color slider to select brown, pink, white, blue, violet, or somewhere in-between.  Next, drag the low and high cut filters to further customize to your liking.  Adjust device volume using the on-screen volume slider to a comfortable level.  You can also specify to play audio to any AirPlay supported device.  Toggle audio playback using the Play/Pause button.

### 1/5 — Sounds weird now and no way to regenerate a new waveform.

*2026-08-19, version 5.1.1*

5.1.1 sounds different than it used to. It makes noise that doesn’t seem to correspond with the hz.
Also, the waveform used to regenerate reset after any change but now it doesn’t, which would be good but there’s no way to regenerate it. They need to add a regenerate button.

### 1/5 — Another update gone wrong

*2026-08-15, version 5.0.4*

Used this to let people know what Tinnitus sounded like. Now it’s far too complicated so deleted as I could  not find my Tinnitis frequency anymore.

### 1/5 — Wow… what happened to this app???

*2026-07-27, version 5.0*

never thought I’d write a review like this. Noise GEN is many people’s go-to every single day. Great for blocking out background noise to focus on studying, for sleep, or fine-tune specific sound colors for sensory relief, this app was an incredible, lightweight piece of audio software. It felt like it was built by people who genuinely understood sound and cared about its users.
Then came the most recent update, and it completely ruined everything that made this app special.
First, the underlying noise generator itself is broken now. the frequencies aren't being portrayed or synthesized accurately anymore, resulting in loud, sharp, and harsh noise profiles instead of proper frequencies. every range sounds like white noise now. 
On top of that, changing the frequency slider from an exponential scale to a linear scale is a devastating UI downgrade. Frequencies and human hearing don't work linearly. Switching to a linear slider completely destroys the precision control over lower and mid-range frequencies, making accurate adjustment virtually impossible. they even removed the stereo balance control entirely. stripping away a basic, essential feature for anyone who needs spatial adjustment or targeted sound tuning.
To top it all off, the app has been bloated with ads. they now physically clutter the lower bar of the app.
It breaks my heart to see a tool that was once crafted with technical care stripped down and monetized at the expense of functionality. Until the audio engine is fixed, the exponential slider is restored, and the ads are removed, I unfortunately can't recommend this app to anyone anymore. Goodbye, Noise GEN.

### 1/5 — Good while it lasted

*2026-07-23, version 5.0*

The latest update broke this app.  The high pass filter is messed up now, and seems to be letting through frequencies way above what it’s set to.  What used to be a soft, low rumble is now a sharp, hissing assault on my ears.  It’s an obvious night and day difference between the two versions, using the same saved preset.  Changing the volume also seems to change the high pass frequency too, which makes no sense.  Overall just a really sloppy lack of QA testing.  I can’t get it to sound right after 10 minutes of fiddling with the sliders, so now I have the joy of looking for a replacement at midnight while I’m traveling.  I guess nothing good lasts forever.  Word of advice to the devs:  If it’s not broken, don’t fix it.

### 1/5 — Something changed

*2026-05-26, version 3.0.8*

Something changed in the latest update.  Volume control no longer works and it hangs my phone. Ads are more instrusive too.  Deleting asap.

### 1/5 — Reduced functionality

*2026-05-08, version 3.0*

Now the frequencies go up in increments of one i cant use the arrows to get a precise frequency quickly. It used to go up in 10 which made it easy to tap to the right frequency, now i have to resort to the slider which is not accurate or the arrows which take forever now.

### 5/5 — Exactly what I need

*2026-02-16, version 2.2*

Nothing complicated, just a noise generator that runs when my phone screen is asleep

### 5/5 — Perfekt & Einfach

*2026-02-09*

Super

**Developer response:** Thanks:)

### 5/5 — AMAZING!

*2026-01-02, version 2.2*

Everyone should know about this app!!!!!!!!!!!

At last! I can make my own noise!!!!! Best thing since channel surfing!

LIFESAVER

### 5/5 — Just it!

*2025-12-03, version 2.2*

Exactly what I needed
