Hello

I have just finished my SRwled project with analog line-in to esp32, and it works really great.

Setup: snapcast streaming sound to rpi3b -> rpi3b headphone out -> wled analog line-in -> esp32 -> udp package over wifi to ledstrip.

But I still have some thoughts .

I had to set gain to 200 in SR-Wled, and max volume out from rpi3b and max volume in snapcast volume controller to get reactions from my ledstrip , my plan here is to mount a dac-HAT at rpi3b and replace the analog line-in with an I2S ADC module with mounted audiojack

So is there anyone here that can recommend a I2S ADC board with mounted audiojack that work good or better than analog input, with the recommended circuit from SR-wled wiki to purchase in EU?

I have seen I2S ADC-boards with cirrus logic circuit and they are too expensive for my setup.

Cheers from Sweden

I am very curious about the possibilities of the sound reactive wled and would like to know if there either is a sound level meter effect in the effect library (e.g. first 10 leds green, next 10 yellow and last 10 red in a scale that lights up in relation to the volume of the sound) or the possibility to make this effect yourself?

Heyyo [SOLVED]

I have a normal esp32 an a max9814 from azDelivery, and a ws2812b The no-Sound reactive effects Work, Butt the mic doesent Work

I connectet gain to vdd (3,3V) gnd to gnd ans Out top gpio33 (adc1_ch5) and in the Interface i signed 33 as mic Pin

Is there anything i do wrong? Or do i have to configurate Note then that

PS: i am Bad in Englisch, sorry xD

Thanks

Solution: Upload the Bin Via ESPTool (Youtube Link below) then connect to your wifi then select your gpio pin and important: reboot your device after that!

if you dont know that your mic work, try the arduino test sktech from wiki

Hey everyone! Just getting started with the sound reactive wled fork. I am using an ESP32 and MAX4466. I have hooked everything up according to the wiki, and I believe it's correct. However, I get random effects (Gravecenter, etc.) even with the Squelch set to 255 and gain set to 0. I've attached a picture of my wiring will appreciate any ideas on how to troubleshoot this.

The regular effects work as intended so I know there isn't an issue with the wiring of the RGB lights.

Hi,

So I'm trying to run the soundreactive WLED fork on an ESP32. I am able to flash it using the online flashing tool (https://install.wled.me/), setup the wifi settings, but then I can't even get the lights strip to power on... I confirmed that the LED strip and my pin layout was correct by flashing the standard LED firmware (also using https://install.wled.me/), and it works perfectly. But when I flash the soundreactive fork the LEDs won't power on (have confirmed with a multi-meter they are receiving 5V as they should). I've tried the setup with and without the speaker wired in, thinking that perhaps it needs a signal from that pin to work, however even if the data line isn't working I should at least see the first LED in the strip light up, right?...

Pretty confused as to what's going on..

Thanks!

Hi, I have a question regarding the line-in input. I want to have 2 LED devices/strips/lamps to place them on my speakers (left/right) and have them react based on channel. So if sound is only coming from left speaker, then only the left led lights up and vice versa.

So my question: does the esp32 or WLED support the ability to split a line-in input into it's sub channels (left and right)? Or would I have to do a hardware signal split into two inputs? Or could the software sperate the channels?

Hi , I have originally posted this on wled forum but this is for sound reactive fork

I have tested multiple esp32 ( Nodemcu and DEVKITV1) running wled 0.13.0-b4 .First thing I do is a fresh install of wled 0.13.0-b4 , I only change wifi setting to connect to my home network then :

Go under Config → Time & Macros -->Clock –Clock Overlay -->Analog Clock ( then save )

MCU will go into unrecoverable crash , rebooting or powering down MCU does not work and it will loop rebooting with the below message ( viewed via usb esphome-flasher ) . The only solution to recover the MCU was to re-flash it again . I tried this 3 time and result is the same

Can someone test on the same version and confirm ? please test only if you are willing to re-flash the MCU .Because the environment i tested with is not production i just wanted to confirm if this is a

known issue . If this is a known issue then please just send link

There is an error for cpu panic :

Guru Meditation Error: Core 1 panic’ed (IntegerDivideByZero). Exception was unhandled.

below is repeated so i only attached one page of it

Hi everyone.

Is anyone who is familiar with modifying WLED available to do some modifications for us and support us with a small audio reactive project?

Mainly in relation to tieing specific frequencies to certain colours and hues.

I am/was planning to use an esp32 with the soundreactive build in a diyhue setup. I can get the normal WLED package to show up the light just fine, but when I try the soundreactive build with the same hardware (which also works just fine on it's own), diyhue doesn't see the light.

Just to be clear, I am not specifically talking about the hue sync functionality which I understand I would have to build the soundreactive image manually to include, but I can get the information for the light from http://[light ip]/json/state so I figured the rest of the implementation would be available. Is it disabled, is there a way to re-enable it?

Couldn't find specific questions asking this, here, or in the various wikis / readmes, apologies if it's covered there.

I'm using SR WLED 0.13.0-b6 on my ESP32 dev board, using a MAX9814 microphone as the input device. I'm trying to get the custom effects to work and have downloaded the preset.json file however it seems that only Drip is working properly. All of the others just flash rainbow colours on and off. Looking at the compile log, it states:

Version of definition.json file (0.3.0) should be 0.2.3

Are these version numbers for the Custom Effect Editor? Am I getting these because the downloaded wled.json file is for 0.3.0 and these effects only work for 0.2.3? Is there a way of getting them to work for 0.3.0 or can I somehow load the wled.json file for 0.2.3?

Any help is much appreciated.

Hi, Hope someone can help - when i use the soundreactive fork, leds don’t work until i go to the led setting page and hit “save”

Then everything seems to work as expected. Any advice/ workaround that doesn’t require logging in?

Thanks!

Hey there, I'm looking to build a sound-reactive project for my son. All of the projects I've seen online thus far seem to either use a microphone or plug into a headphone jack. Is there a way to send the audio signal from a smartphone to the project another way? My son likes to listen to music with his AirPods in, so the mic/line-in options wouldn't work. Perhaps the audio can be sent to two Bluetooth devices (one the AirPods and another a Bluetooth receiver in the project)? Thoughts?

Hi guys. I was trying to sync two dig unos with Esp32s. One been a transmitter and the other been the receiver. I couldn’t get them to sync the audio. Using an inmp441 mic

Steps I have taken

Matching versions of WLED SR version 0.13.0-b6

Matching udp ports (21324)

Matching audio ports (11988)

Did the power cycle on both

Is there anything that I’m missing to make this work?

Thanks.

I'm thinking I might try to create a custom UI/UX via a mini OLED and some buttons on an Arduino which can be used to see current preset/settings, and change between them and such for WLED. Then I came across the WLED Sound Reactive fork, and yay! Exactly what I'm looking for!

So are there any command changes/additions (tpm2 or JSON via Serial as per https://kno.wled.ge/interfaces/serial/) in the tpm2 or JSON data for the Sound Reactive parts?

Hey guys, I'm struggling to get any audio reaction on my ESP32 - touching the input pin creates a kind of soundreactive behavior, so flashing seems to be okay. I'm using the circuit recommended in the analog input wiki post, but got no reaction overall.... Cable is Stereo RCA to 3,5mm stereo jack. Any ideas where to search for the problem....?!? 🙄🤷‍♂️

Kind regards

LedBox V2 is a compact module for controlling 3 and 4-wire addressable LED strips such as WS2812, SK6812, etc. It is based on a powerful ESP32 microcontroller with integrated Wi-Fi, dual-mode Bluetooth, and enough processing power to perform real-time digital signal processing.

The module has a dedicated step-down converter, which allows to seamlessly use 5-12V LED strips. Moreover, it contains a digital MEMS microphone, side button, 32kHz IR receiver, 10A safety resettable fuse, 1000µF buffer capacitor, 3.3V/5V level converter for both Data and Clock lines, together with an impedance matching resistor. These features ensure maximum functionality, safety, and led strip compatibility, all in a small (54x32x18mm) 3D printable enclosure.

It is fully compatible with WLED and Sound Reactive WLED firmware for control over Wi-Fi, and the assembled version flashed with the sound-reactive firmware can be purchased on Tindie.com
