I immediately apologize for my English, but I will try to tell you about my, as I call it,
RTMV-technology.
You will agree with me that lighting, in any show, is as important as the music.
For grandiose shows, a light part is written specifically for lighting fixtures, which has synchronization with a piece of music. For this, as I think,
there is already such a profession as a
lighting engineer.
A lighting engineer such as a composer of light, a lighting artist. And talented people create really amazing lighting works. But there is one thing, but.
All this is done for one performance, for one SHOW. If such a light SHOW is viewed several times, it begins to “pall” with experience and the person
experiences disappointment, i.e. comes the so-called - the effect of fatigue.
But I think the demand for the light accompaniment of a musical work is quite large. There is only no theory that could describe the principles by which
it is possible to create such an instrument or device that could, without human intervention, in real time transform music into Light Images.
Yes, according to the very first ideas, in world history, in which there was an attempt to visualize music, it was always about creating light images.
For everyday purposes, of course, no one will invite a lighting engineer to write a light part for one track. For household devices or for instruments,
for example, a DJ workplace, a device is needed that can enhance the perception of a piece of music and at the same time be completely autonomous and not create the so-called fatigue effect.
The effect of fatigue is associated with the characteristics of a person, human memory can remember a lot of visual information and devices with
a limited algorithm easily, literally in a week, visualizations become unattractive.
What CLUBBEST is is a simplified version, 1D visualization, it uses simplified algorithms that MCU with 15 MIPS performance can implement. A big
limitation is already imposed by the use of
WS2812, 8 bits per channel and color limitation, the need to implement a non-standard interface,
low data transfer rate.
The CLUBBEST architecture was chosen from the technical capabilities that I could get on the territory of Ukraine and using the assembly capabilities
in China (but now it’s very sad, the Chinese have now closed the possibility of selling components and assembling printed circuit boards for Ukraine,
being afraid to fall under sanctions).
The whole project was conceived to be an inexpensive device that could be connected to a PC, home theater or DJ console quickly and easily,
it should not have any manual adjustments, all processing should be completely automatic and have acceptable visualization.
If frankly, not everything is as simple as it looks. Even the shape of the rise and fall of light plays a big role in perception. And all these small
features require additional MCU performance.
There are interesting things, the human brain, depending on what color he saw, then after it is extinguished, he can finish painting a completely
different color afterglow.
There is such a thing - what a person considers beautiful. For example, if the image of the image is symmetrical, it is always beautiful.
Rhythm has a very important place in a piece of music. But in any rhythmic music there is a melody. Here I am trying to implement the solution
to these problems in RTMV-technology. Of course, I practice at an amateur level and in my free time from the state of survival that is now in Ukraine.
For such studies, one must devote 100% of the time to have good equipment for sound analysis. But as practice has shown, even in such a limited
implementation, RTMV-technology shows good results.
Now for the CLUBBEST option - two models have been created:
CLUBBEST M68 Master and Slave. This is the synthesizer itself and the repeater module, purely an additional screen. In the video, they stand
on a rack one above the other. But there are "legs" for each module separately and they can be placed to the left and to the right of the viewer.
If used in such a variant as in the video, CLUBBEST should be placed in front of the viewer and always horizontally, this is important for perception.
The second option is CLUBBEST M100, everything is almost the same for everyone, but it has much more, the so-called “visualization matrices”
are generated and its perception of its visualization is more saturated.
The main advantage of such a music visualization tool is the resulting low cost, and if you organize its mass production, then you can get
a good profit at the level of $ 200-300 per product.
Disadvantages, of course, there are many of them, and all of them are associated so far with the impossibility of implementing full-fledged
RTMV-technology algorithms on the material base I have.
Well, here's the problem - the
WS2812 has a too slow data bus, with large numbers, the synchronization pulse becomes so large that it really
slows down the visualization.
http://www.normandled.com/Download/index.htmlFor such purposes, it is more efficient to use, for example
APA102, they use the ala-SPI interface. And modern options allow you to transfer
data at speeds up to 40 MHz, and this is not 800 kHz like the WS2812 and with small arrays of LEDs.
https://www.addressableledstrip.com/home/download/index/catId/17.htmlThe next one is 8 bits, which is very, very small. Now there are 16-bit LEDs such as
HD108 or
NS108, in these LEDs you can get amazing
color components, but for such purposes, processing speeds of 600MIPS or more are needed.
Maybe there will be a sponsor who will be interested in this topic, then such a CLUBBEST visualizer will appear for anyone who is fond of
and appreciates music. But so far, only individual orders and the manufacture of single copies are a little expensive.
If you are interested, you can see my development steps on my channel https://youtube.com/@CatcatcatElectronics The main idea behind the technology is to see the music!
