This looks great for my project, how easy is it to use a Max4466 mic instead for audio input?

Hi Can you share files with Easy EDA? Regards

Hej Czy możesz udostępnić pliki Easy EDA ? Pozdrawiam

Hello, and thank you for the video. Question: In loop you start reading the buffer but did not check to make sure it was full. Also did not read the 2nd buffer. I would thing there would be some synchronizing of the dma buffers and your code. Like dma buffer 1 full, read buffer1 to mybuffer1, do whatever to data, dma buffer 2 full, read dma buffer 2 to mybuffer2, do whatevver. I think I am having this problem because a lot of examples just reading writing and not checking status. Is this a legitimate question ?

cool stuff!

amazing!

Great results! How can I contact you to discuss a flyback transformer for electrostatic loudspeakers?

Hello. I bought this via your commission pcbway link but I have two questions, What are the 3 jumpers? (two 2 pin white ones and a black 3 pin one), also which is the positive/negative inputs?

GERBER?

Nice project

Thank you 🙏👍🏼

Trying to adapt your 10 analog bands analyzer to my needs. Could you give me the reason for using the multiplex device? Could the 10 bands outputs be tied together and sent to the ESP32 directly? I made your 32(64) channels fft version and it works ok, but don't trust its accuracy in the high frequency bands. I use line input and TFT Displays for my needs. I display 13 amplifier outputs: Subwoofers, Low Woofer, Mid-Range, Ribbons, Surround, Height and Center Stereo channels. I use Car Stereo (transformer) attenuators to bring the amp output to line level. I will add two more analog channels for 10K and 12KHz. Interpolating the values of R1, R2, R3. I only need the frequency spectrum.

What progress have you made so far?

Congratulations for this amazing project! I am a Computer Science Professor and this project will be part of my classes ! I am studying hard your code... One question please: How can i configures a strip led version to be 32x32 ? Best Regards

Nice refresh rate! The natural development of this device is to make HDMI output and forward to a large wall mount LCD. This will of course require a more complex and detailed visual interface.

How if we connect to led strip

If you get I2SPLUGIN ERROR RELATED to ADC_GPIO_init or no visible lets after compiling. Make sure to downgrade all your libraries to the version I used! check the manual. Manual and drivers needed are on the github. Link in description above.

Too fast

Looking forward to seeing it

Fake video 😂

Awesome🥂🥂🥂Thanks

Please upload the gerber files also so we can upload and make our own pcb

Hi, when i compile your code a get an error :( Compilation error: 'adc_gpio_init' was not declared in this scope what what be causing this ?

Wow, just wow. I'm also trying to make my own vu-meter and found your video and exposes all my doubs. All my sketchs using FFT shows the same issues: some sounds, specially short ones, line drums or finger snap, as seen here: ua-cam.com/video/PdaYj1fz3k4/v-deo.html, using FFT are missing! I'm in the way to find what's going on with FFT, but, anyway, analog filtering ends up to be more natural and for sure I'll take a deep look to your MSGEQ7 project. I think that FFT issue comes from the time that ESP32 is doing other things than reading signal. But, not sure at all.

wow CO2 laser cutter? wow high tech

WhatsApp number

Wow Tesla.

Haha Toy gun, safe and funny, good idea

its work with hub75

By Combining you make it amazing

Was wonder are you planning to have the pcb available for order? Thanks!!

Something I've been wanting to do for years. I would need two built. One left & one right. Each one receiving it's own input vía RCA (mono) No Bluetooth no WIFI just a signal from my source audio source using RCA... Is this possible?

Absolutely great knowledge and presentation! Thanks!

Mark, thank you for your work and for sharing. The spectrum visualizer looks very nice on the small screen (with a smooth decline/lowering of bars from peaks), is it possible to make it the same on the matrix? And the second question: how did it become possible to eliminate all the settings (manual)? As it had a place for adjusting FFT frequencies on ESP32 analyzers.

very nice..

range?

No its drawing the dame bars but starting from middle and indeed mirrored

Looking good mark! 👌 I have version 1.0. But i read it is backwards compatible. Oh man!!! Maybe i`l try it. But the 1.0 runs nice to!

Nice. On the LED matrix at 3:18 is it artifically mirroring the power spectrum along the x axis or is it actually displaying the audio waveform?

Wow why is he there in your channel ?? Lol How is it possible?

I love all your work, thanks for sharing.

Hi ,thank you for you explanation. I have a fundamental problem, just starting with the first method if I just make a simple program with a loop that reads values and increase a counter , after 1 second (1.000.000 micro) my count is only 10.000 times. That means that I am taking samples at maximum speed of 100 micros por sample. You see? with this numbers your example shouldn't work! (you are taking at 20 micros per sample, I don't know how) . I am using an esp32, first I used an arduino nano and the maximum count gave me samples times in a second, that is why I changed to esp32, imagine my surprise when I run the same program and I only got a 10% increase in the count.

Wow great idea

Very nice project and execution. Brilliant! (get the pun?) 😏

That looks cool

Too cool! the banding is amazing, and it is also cool that you did it with a normal erlenmeyer flask

Super Cool Mark! I'll be looking forward to some new visualizer screens. I can't wait!

great work its cool

Hell yeah, can’t wait!!

wow i salute to this talent
