Arduino / ESP32 32 Band Audio Spectrum Analyser 

Awesome project. Any chance of sharing the schematic and code or even selling the plans? I'll pay.

please !! can you share or sell your code and building step by step ??

What a beauty

I would also ask similar as others asked already: is this project strictly "only one in the World", or maybe can be shared - code, schematics? Optionally maybe - sold (code, schematics)? Thank You in advance!

ADAM......HI You've forgotten about us...... I believe we all love this project..... But we need the CODE.........

Is it possible to get the code for it ? I would love to build this exactly like you but have not much experience in Arduino 🙈 Greetings from Germany 😋

can you please share the code?

can you share the code.? if not can i buy it because i really need it.

Hi Adam Theo from Greece here. Have been trying to make something like this. Do you have a schematic and code? Or do u sell.... Anyway, I'm interested. Pls don't keep us in the dark Thank in advance.

Can you share the Arduino codes? Or a place to buy this? Can you please let me the size?

Please diagrams & code

Adam, Cool project. Are you going to be sharing the code. Want to see what can be done to go on to a larger sized screen for a school project

Very nice project. It would be great to get the code. Do you provide that to a learner? 🙂

I want buy it.

I guess dead project?

good working adam please coding adam thaks

Kindly share your code and sketch

Verygood!! Nice!!!

This is awesome. I want to do this for the trunk of my car. Any chance there's a video putting it all together ?thanks. Cheers.

Hello. Your Audio Spectrum Analyser is very nice, congratulations. Can I buy the circuit diagram and codes?

would it be possible to have the diagrams and the Arduino code Thanks

Could you share the code for it? I'm willing to pay for that. Thanks

Saya dari Indonesia.. Ingin Membuat Ini Bagaimana Caranya

Crap video?! WHERE?! Love your project.

Build plans and code by any chance plz?

Waw never seen so cool effects!!! Better than SP107E. Awesome job. Will the code be shared?

Wow adam, very nice project :-) Please provide the code, i'll pay for it. Please

Это самый лучший вариант

Please code & shematic Credit to you of course

Anyone using ministry of sound in their demo has to have at least 5 stars ⭐⭐⭐⭐⭐

Que sentido tiene presumir de una tontearía

Are you open to doing some paid consulting?

I want to build something like this so much. I have zero experience with Arduino coding though, I do have access to a 300w co2 laser and cnc routers though... Any chance you may sell the schematic and code for people like me?

Good day. Where can I download the sketch?

Haha that's some cool unconventional effects there! Nice.

Здравствуйте как сделать ваш проект

Мой дорогой друг , поделись пожалуйста кодом , переделаю на другую панель поделюсь с тобой

Very cool project Adam. Are you gonna be able to share the code and build instructions? That will be nice. Thanks!

I can at least give some guesses as to the chip setup based on looking at the datasheets and scouring for info. The MSGEQ7 is a 7 band audio amplifier. Not sure why there is only 7 bands but possibly real music and speech has frequency content that octave-wide bands capture optimally. The creator mentioned 32 channels, which you can get with 5 of the MSGEQ7 chips by running them at different clock rates The different clock rates come from the 2 SI5351 boards (3 clocks each. Samples would be as clk1 = f, clk2 = (1.20112 *f), clk3 = (1.20112 * 2 * f), clk3 = (1.20112 * 3 * f), and clk3 = (1.20112 * 4 * f). Now you have FIVE 7-band analyzers, but their center frequencies are offset by 1.20112X. Why "1.20112 * X"? The MSGEQ7's center frequencies are 2.5X multiples. To divide that into 5 segments, take 2.50 to the fifth root, which is 1.20112. So you get a 35-band analyzer with 35 different bandpass filters at 35 different center frequencies. The bands are WAY too wide and their skirts overlap a lot but so what, you're a hobbyist, not an acoustics Ph.D. This really frees up the ESP processor to do the fancy display work and drive the LEDs

Gdzie mozna znalez/ kupic kod?

Il codice... Babbeo!!!

Awesome!

code?

What is the 1st song of this music?

Link shopping?

5xMSGEQ7s. Curious as to how you wired those.... they have fixed bands, so unless you can offset the frequencies somehow to create 5*7 bands. Any hints? I have started one with a 32x8 grid using Bluetooth and an FFT. Just doing basic spectrum on that only gets me 30FPS. Your idea of using hardware EQ ICs to generate your bands is very interesting, you don't even need to handle any sampling or even digital audio at all!
