The app comes with a handful of simple, yet outstandingly implemented visualizers and each has multiple color themes to choose from.

Feature Highlights:

● High-speed sampling for fluid, responsive graphics
● Multiple color themes to choose from
● Automatic gain correction for loud environments
● Microphone sensitivity level control


***** "If you liked the cool graphic equalizer on your super-old stereo, this is for you!"

***** "If you're an audiophile, musician, DJ, or simply an appreciator of music, this app is definitely worth it!"

***** "Set your iDevice down near the speakers at any party and you have a great visual add for your guests!"

Exactly what I was looking for my vinyl setup. Only issue I have is that it doesn’t seem to support full screen on my iPad when it in landscape mode. Am I missing something?

### 3/5 — 아하…

마이크 소리에 따른 비주얼라이져인지 몰랐네요…

### 1/5 — Need blue tooth connectivity

*2021-01-10*

App is great exactly what I am looking for but useless without connectivity.  I would gladly bay $20 more if it had connectivity

**Developer response:** Hi John, 

This is a technical limitation and is out of our control. 

As stated on the app store description and screenshots: "Currently Bluetooth is *not* supported. The app uses internal microphone and speakers only. Do not download if Bluetooth is required." 

With any issues please contact us directly at apps@onyx3.com. You can also request a refund if the app is of no use for you.

### 5/5 — Works wonderfully with the new iPad Mini

*2019-11-09*

It’s a nice app, the graphics are elegant and very satisfying!
An unique visual upgrade for any sound system.
Works flawlessly with the new iPad Mini .
Worth every penny! Recommend!

### 4/5 — Simple but

*2019-11-08*

How about a threshold adjustment?
I don’t want to turn down mic but I want it to settle out between songs. 
I like it while music is playing but it’s still jumping all over between songs. 
Love the bars but I’d also like to adjust width. 
Keep up the good work. 
I’d love to see an Apple TV version.  Currently I’m mirroring my iPad. 
Thanks
