Let your Razer Chroma-enabled devices rock to your beats with the beta Audio Visualizer, developed on the latest Razer Chroma SDK 4.8.

Fire off the colors not just on your Razer BlackWidow Chroma, but also on the newly supported Razer Mamba TE & Razer Firefly!

*EDIT* 19th January 2016
Hey everyone! I can't believe it has already almost been 4 months since this post came up and Chroma has come a long way since then! The Audio Visualizer is no longer an early build and the setup process is very simple, I've updated the steps below accordingly.


We’ll let the video du-du-du-du-do the showing:



We really appreciate all the work our community developers have put in to push the potential of the Razer Chroma technology and our friend @CalcProgrammer1 has really done a solid job on the Audio Visualizer. This new Audio Visualizer gives you the freedom to customize the color scheme and tweak its amplitude so you are only limited by your own creativity. Did we mention it’ll not just react to your music, but also to game audio?

Here’s how to get the fun started:

  • Ensure that you have connected you Chroma device and updated Synapse to the latest version
  • Once updated, make sure that under your Chroma device > Chroma Apps tab, you have "Chroma Apps" turned on
  • Head over to the Chroma Workshop and download the Audio Visualizer
  • Install the vc_redist.x86.exe file that comes together in the zip
  • Launch the Audio Visualizer and get rockin'



Have a go at it and show us what you are doing with your Chroma hardware.

FAQs:

To those facing the "mfc140.dll is missing" issue
Download the Visual Studio Redistributable version "vc_redist.x86.exe"

As this is a very early build, it clashes with Advanced Configurator occasionally.
Change your effects to the default ones e.g. Wave, Spectrum Cycling. You can then launch the application and your keyboard/mousemat/mice will show a blank slate until a sound is played.

What products does it work with? *EDIT*
It works with...

  • BlackWidow Chroma / TE
  • DeathStalker Chroma
  • Firefly
  • Diamondback
  • Naga Chroma/Naga Epic
  • Mamba TE/Mamba wireless
  • Orochi
  • DeathAdder Chroma
  • Tartarus Chroma
  • Orbweaver Chroma
  • Kraken 7.1 Chroma


The visualizer bars are really low, anyway to fix that?
You can bump the bar's height up by increasing the amplitude or your volume (not too much please).

How do I get the colours like the ones in the video?
Adjust "Foreground Mode" to the colour scheme that you like. In the video, I used "Rainbow Inverse". You can also add a "Background Mode" should you like.

Does it react to any sounds besides music?
It takes your Windows sound input, hence any sound - including your games or movies!

Do I have to turn off Synapse?
Closing Synapse before launching the app will be the safest.

Keyboard goes black but it does not react to any audio
As the program is reliant on some limited functions by Windows, be sure that your volume is cranked up or adjust the "Amplitude" to a higher value (Try in the 500s or 1000s)

I can't get it to work due to misc reasons that we have yet to identify
I apologize for this, this was meant to be a beta build and I shared it earlier as I knew the video will get you guys psyched for the app! We are using your feedbacks to build a better experience.

While it may be tedious right now, we WILL be reducing the steps and processes in due time with Synapse and etc. That is on top of more product support. Hang in there!

So this was cool but now I can't get my old settings on the synapse to work.
A
It doesn't work for me. 😞 Do i need to set something in synapse or how do i save it? Can't figure it out. Please help.
A
I can't get the visual redist x86 to install..there's always an error..it says microsoft visual c++ has stopped working..everytime. HELP
A
apparently, this doesn't work anymore while synapse is open (since there was a new synapse update)
A
works pretty well for me. only have 2 problems with it. after restarting my comp i have to reenable sdk support and if i switch my audio device to my headset it no longer works. only works when playing through my speakers.

Hi! This is awesome, only one problem though.
I use Kraken Pro, but when i use the KeyboardVisualizer the visualizer doesnt cover the whole keyboard, sort of speak. It only shows the visualizer to the right, and the left side is almost blank.
But, if I turn off surround on the Kraken first (with Synapse), open Visualizer, and then turn sorround back on, the visualizer covers the entire keyboard as it should. I dont know if this is something I can fix, or if it's a bug or something :)

Here it is with surround on from when I start Visualizer:


And here it is when I disable sorround first, then launch Visualizer, and then turn sorround back on.
Same song, both after 7:00 exactly.


This was probably quite confusing to read, so for that I am sorry, I'm not that good at explaining things, haha 😛

Mouse cursor not moving while using visualizer for a few minutes. but the light are still going on my Mamba TE. Does anyone here experiencing the issue?
A
FOR EVERYONE WHO SEE THE PREVIEW BUT NOTGHING HAPPENS ON KEYBOARD:

I had the same problem but then I installed both SDK Support .reg files and it works now!

omg i love you man, haha thanksss

For me it just says: "KeyboardVisualizerVC.exe has stopped working...." as soon as I try to launch the program 😞
Sixie
so this doesnt work on Razer Mamba 16000 ? (Chroma) yet

i cant download the Visual C++ Redistributable for Visual Studio 2015 from the microsoft webside... what a joke
A
Well a big problem with RK7.1Chroma is that it annihilates the visualise to the point were you cant even load it up. So... Sorry for those that use RK7.1C (including me ;-;)
A
Please include this in Synapse as soon as possible!
A
holy crap. it worked, thank you so much, i like setting mine to background rainbow (very dim slow rainbow wave) and inverse rainbow foreground with a high amplitude (1000 now still tweaking)
A
Not working for me, if I open the visualizer without Synapse open it just turns off my keyboard lights, I've set my lighting mode to static, restarted PC, even uninstalled and re-installed everything needed, but still nothing shows on the keyboard?

Same goes for if I open the visualizer WITH Synapse open, it just shows the static color. Even though the visualizer demonstrates a preview of the frequency, it doesn't appear on the keyboard.

I've installed the SDK Support.reg files also but still no luck, not sure what the issue is but would love to see this feature added to Synapse soon!

Suggestion as to how this concept should develop:
The audio visualizer should be an effect implemented into the advanced configurator. So that i could layer other effects over it such as static keys in which i do not want to change colors with the visualizer. And possibly be able to select which audio device that the visualizer will use.
As of now this works good and looks great
A
It works perfectly by me but now, I have a problem... I can't change my visual setting of my keyboard anymore... I switch profile, but the lights stay "by default"... 😕 What could I do?
A
Anyone else having problems with the mouse not working after a computer restart while this is installed?
Have to re-plug it each time...

work good but I don't know why i need to crank up my youtube and windows volume to 100

Under the format tab of the audio settings, what frequency are you using? If it's high (96000 or 192000Hz) then that should condense the waveform to the LEFT side of the keyboard. It's a known issue, as I'm assuming CD-quality 44.1KHz input. I skip every 4 samples to effectively have an ~8KHz data sample to run the FFT on which becomes the visualizer. If I did much higher than that it would lose detail at the low end. On systems with higher sample rates, this skipping every 4 produces a result that is essentially 16KHz or higher, which compresses the visualizer by nature of the frequency change.


I know this is an early version, but not being able to use 5.1 sound configurations if we want to get a good visual effect is not worth the sacrifice for the moment.
Are you going to fix this in a future update so that the effect is spread across the whole keyboard and not only in the arrows area?
Tried with different frequencies but the effect is still isolated in this area while using 5.1.

Thanks!

Problem is I can't test everything. The Windows Audio API sucks in that it doesn't do any cleaning or anything, just dumps you an audio stream. If you're using something I don't have to test on like 7.1 192KHz, then the data your visualizer receives will be interpreted incorrectly. I can prpbably fix the frequency issue but I have no idea how channels are distributed and the volume control issue basically comes down to being out of my control. Windows may or may not apply volume depending on device and the result is what I have to work with. The only solution is to increase amplitude in my app if your volume needs to be cranked up and balance the amplitude vs volume yourself.

It shows in the visualizer, but the keyboard does nothing. What am I doing wrong?

what is the highest amplitude we should go to
