Welcome to our Sound Reactive fork of WLED. In addition to the features of WLED below, we also support:

• Audio input from several sources including high quality I2S digital (INMP441, ICS-43434, SPH0645, etc) inputs, analog devices (MAX4466, MAX9814, MAX9184, INMP401) and line-in.
• Volume reactive visual effects for ESP32 and ESP8266 devices.
• Frequency reactive visual effects for ESP32 devices.
• UDP sound synchronization with transmit for ESP32 and receive for ESP8266 and ESP32 devices.
• 2D visual effects for ESP32 devices.
• Squelch and gain settings for ESP8266 and ESP32 devices for the volume reactive visual effects.
• 2D settings for ESP32 devices.
• Frequency reactive sliders for ESP32 devices.

We currently have 3 active forks for our Sound Reactive WLED. They are:

• ESP32 standard version (ESP8266 is no longer supported)

ESP8266 branch - When do you merge upstream v0.13.0-b2?

Hi!

As stated in the subject, I'd like to know, if you will merge upstream to ESP8266 branch in the near future.

Besides, keep up the good work :-) many thanks!

ESP32 not enough memory?

Hello,
can it be that the ESP32 has too little memory when Alexa or infrared is activated?
I get the error "too little memory" when I activate Alexa or infrared in the Sketch.

I have somehow managed to install "WLED version 0.12.1-b1" and I can't seem to find it again

Hi,

Thank you for your excellent work on this project, it really is fantastic and much appreciated!
I have a bit of a random question. I set my lights up (3 EPS 32's) some time ago and was just about to set some more up now.

I can't figure out how but I seem to have WLED 0.12.1-b1 (build 2105112) currently installed on the ESP32's with the sound reactive functionality with the sound option in the menu. I can't however seem to find the binary for this anywhere now!? The releases page only has bin of "WLED 0.12.0 (build 2104030)" ?! I feel like I'm being really silly but just thought I'd ask what was going on!?

Relay Wled & Sound

Hello, I use WLed with sound. With Wled without sound you can connect a relay to D6. But that doesn't work with Wled with sound. Is there a way to switch a GPIO when Wled with sound is switched on?

How to get Automatic Gain Control (AGC)

I'm building a sound-reactive hat. As such, it'll need to work in environments with rapidly changing sound levels without manual intervention.

• Is there a way to enable AGC in sound reactive WLED?
• If not, I'd be happy to attempt a PR, but I could do with some pointers first

I'm generally happy coding/building/testing WLED, but am not sure where the best place in the code would be to integrate such a feature.

Any thoughts or insights most welcome.

2D GEQ: led count per band not correct

If no sound, no leds should be on. Currently the lowest row is always burning. Cause looks like a programming bug:

File FX.cpp:5157
if (i <= count) should be replaced by
if (i < count)

Can you please replace this in a future version.

Thx,
Ewoud

VBAN

Hello,
First of all, I very appreciate your cool project, but I was wondering if will be posible to not use mic for soundreactive, but direct VBAN audio stream, there is one nice sketch that can easily convert VBAN stream to Int value.

Can we sync multiple lights by sound Reactive?

For now,only ordinary effects can be synchronized, can we sync multiple lights by sound Reactive?

WiFi initialization "hangs"

Hi Andrew,

I'm sometimes switching between my own Fork and your Fork. I noticed that after doing that, sometimes WiFi doesn't connect. It also doesn't initialize it's own Access Point.

I've done some debugging and have managed to get some information. This is the code-trail:
wled::loop -> handleConnection
wled::handleConnection -> initConnection
wled::initConnection -> WiFi.config(0U, 0U, 0U);
(WiFiSTA.cpp)WiFiSTAClass::config
(WiFiGeneric.cpp) bool WiFiGenericClass::mode(wifi_mode_t m)

Eventually the following statement gets called (with m=1,_persistent=false):
err = esp_wifi_set_mode(m);
For some reason this statement never returns. However if i change to:
err = esp_wifi_set_mode(WIFI_MODE_APSTA);
the statement does exit.

I'll update this issue. When i've found a solution or root-cause.

A suggestion for the documentation

Hi!

I have a suggestion for the documentation. In the chapter about First Steps, a text about how to connect to the device could be added:

First Steps

After uploading WLED to the Esp, use your phone and connect to the WLED-AP using the password 'wled1234'.
Click 'Login to network' when the notification about this shows up. You are then transfered to the WLED's start page, and here we should click "WIFI SETTINGS" to connect to the local network. Fill in the settings for your local Wifi network, and then click 'Save & Connect'. The device will reboot and if everything worked it will now be connected to the local network. Finding it's IP-address can be done via the network routers administration page, or via an mobile app like Fing were you can find a new device called "wled-WLED". Open this IP in a webbrowser to access WLED's control page.

1. On the WiFi Setup page, it is highly re...

Wifi Issues

Hi and many thanks for the nixe sound reactive wled project,

i´m very new in wemos stuff and my project starts with some wifi trouble

i use two china nodemcu esp8266 for my wled setups.

after a while using the lights, they are not reachable anymore, after a reboot it works for a while again.
they are showed connected to my wifi but they are not reachable.

any ideas?

best regards

Will there be a 0.11.1 8266 build?

Hey, thanks for the latest update... Will you compile a esp8266 build? I only see the esp32 builds currently

Input monitor

It would be great to have some kind of monitor for the input source in the UI to help tweak the gain and squelch values. I'm thinking of some small graph showing the peaks/lows.

Button and Macros

So in the settings it says the macros have moved, and I can somewhat see where I'm supposed to edit the API under presets, but I am still unfamiliar with how to go about this, haha. Previously I used a macro someone had where it would use a button press to cycle through effects

FX=~

But I cannot seem to implement this into the API, moreover I would be more interested in making the button press cycle through my custom presets.

If anyone could help it would be greatly appreciated.

Enable USERMOD_DHT with SoundReactive WLED

Dear Team,

Firstly, I would like to say Big Thanks for this such amazing and great project. I love it.

All time you guys, helped me out if I needed. Now, Again I am seeking your help in order to enable the DHT22 sensor with my SoundReactive LED.

I am using:
WLED 0.12.0 latest source code
ESP32 Dev Module
DHT22 Sensor

I tried it many times by modifying the source code and complied. But that didn't work for me. I am not sure, where I am doing mistake.

Below is given:-

In usermod_list.cpp, I have defined #define USERMOD_DHT

As documented, if I am copying platformio_override.ini file in root directory, then I am not able to compile the code. Therefore I have modified below in platformio.ino

[env:soundReactive_esp32dev]
board = esp32dev
platform = [email protected]
upload_speed = 921600
;upload_port = /dev/cu.SLAB_USBtoUART
;monitor_port = /dev/cu.SLAB_USBtoUART
build_unflags = ${common.build_unflags}
build_flags = ${common.build_flags_esp32} -D WLED_DISABLE_MQTT -D USERMOD_DHT -D USERMOD_DHT_CELSIUS -D USERMOD_DHT_STATS
lib_ignore =
ESPAsyncTCP
ESPAsyncUDP

And add the library to lib_deps =
https://github.com/alwynallan/DHT_nonblocking

I am able to compile and upload the code, however not seeing AP "WLED-AP".

Please help me out , how I would be able to enable DHT22 sensor with my soundReactive WLED.

You'r response would be highly appreciated.

Thanks very much
Amit Kr. Singh

volume controlled brightness

Hi Atuline,

I think it might be an interesting idea to use volume to control brightness of an effect, for example the spectral effect could benefit from it. Is this something considered before? In that case volume controlled brightness would be a checkbox per effect or a general setting.
In case this is complex, could you add 'spectral-by-volume' as an extra effect? I guess this will become my favorite ;-)

Add log file info to the Info page

This feature suggestion is quite simply to add the log file info to the info page.

If I boot up Wled when it is connected to my computer, the log file shows info as follows:
[09:35:00]eI2S driver installed.
[09:35:00]Digital microphone is NOT present.
[09:35:00]Ada

My suggestion is to simply add those lines to the Info page, or even a "Show boot log" button to the info page. If further information is useful then that could also be added.

2D led matrix horizontal or vertical

Tried to find how the recommended positioning of a 2D led matrix is. Eg if you do the chase effect, should it go from left to right or from top to bottom? Could not find it in the documentation.

Watchdog trigger in function mode_chase_flash_random (deleted was not for fork)

Describe the bug
if I let run the mode: chase_flash_random long enough (like 5mins) I get a watchdog trigger error

To Reproduce
Start the chase_flash_random mode and wait

Expected behavior
Should not trigger the watchdog

WLED version

• ESP32 dev
• Newest stable

Additional context
The error says that it triggers here:

uint16_t WS2812FX::mode_chase_flash_random(void) {
  uint8_t flash_step = SEGENV.call % ((FLASH_COUNT * 2) + 1);

  for(uint16_t i = 0; i < SEGENV.step; i++) {
    setPixelColor(i, color_wheel(SEGENV.aux0)); <--------------------------- HERE
  }

  uint16_t delay = 1 + ((10 * (uint16_t)(255 - SEGMENT.speed)) / SEGLEN);
  if (flash_step < (FLASH_COUNT * 2)) {
    uint16_t n = SEGENV.step;
    uint16_t m = (SEGENV.step + 1) % SEGLEN;
    if (flash_step % 2 == 0) {
      setPixelColor( n, SEGCOLOR(0));
      setPixelColor( m, SEGCOLOR(0));
      delay = 20;
    } else {
      setPixelColor( n, color_wheel(SEGENV.aux0));
      setPixelColor( m, SEGCOLOR(1));
      delay = 30;
    }
  } else {
    SEGENV.step = (SEGENV.step + 1) % SEGLEN;

    if (SEGENV.step == 0) {
      SEGENV.aux0 = get_random_wheel_index(SEGENV.aux0);
    }
  }
  return delay;
}

Right now I could temporary fix the trigger with this inside the service loop

TIMERG0.wdt_wprotect = TIMG_WDT_WKEY_VALUE;
TIMERG0.wdt_feed = 1;
TIMERG0.wdt_wprotect = 0;

TIMERG1.wdt_wprotect = TIMG_WDT_WKEY_VALUE;
TIMERG1.wdt_feed = 1;
TIMERG1.wdt_wprotect = 0;

and this in the fx.h

Help with UDP data

Hi

I'm trying to use the UDP data emitted by WLED using https://github.com/atuline/WLED/wiki/UDP-Sound-Sync as a guide.

Am I correct in thinking that "fftResult" is 16 bytes representing the level of each frequency band? So if it's quiet, all bytes will be zero? If I'm playing something with heavy bass I'd expect to see the value increasing in the first 8 or so bytes. Treble would be in bytes 8-16 etc?

Or have I got the wrong end of the proverbial stick?

Hello thank you for your work
I use the latest compiled version to have alexa
I have a microphone on a ribbon and another ribbon without a microphone I transmit the sound of the first ribbon to the second everything works correctly except the waterfall which lights up just white on my second ribbon and works on that of the microphone

besides, is it useful to transfer the sound to another led tape or to just make a sync it comes back to the same of course if we use the same program I think it is useful to transmit the sound if the presets are different thank you anyway I also have to dig what is effect with the colors I sometimes do not understand I do not have a lot of color I have to leave default for the colors and applied the effects that's it thank you

esp 32 and immp441 for first strip and esp32 for a second strip

How to use the new macro system?

I would like to have a button act as a momentary switch to a certain preset which will take over until the button is released and then return to previous program.

Use case is I use this on a motorcycle and would like to use your fork to add the sound reactive functionality, but I also like to wire in my brake light to turn all the leds red when braking.

INMP441 doesn't work when ESP32 DEVKITV1 is powered via VIN

Describe the bug
Hi, this is a really weird possible bug I've encountered. I have 120 SK6812, so RGB + White Channel, which have been configured and are working as expected. The whole system is powered by a legit Meanwell 10A 5V PSU. +5V and GND from the ESP32 and the LED strips are connected directly to the PSU, which has been configured to output 5.05V. The INMP441 Digital Microphone and LED datapin are wired up according to the wiki.

I've tested the microphone with the provided Sketch and it's definitely working (reading a bit on the lower side - around 500 on normal loudness music). The LED sound-reactive effects are also working if I power everything via USB (removed 60 LEDs for that). If I use the PSU and no USB cable all sound-reactive effects stop working, everything else is working as expected.

I at first thought this might be related to some weird noise in the power system, so I added a cap to the 5V line (35V 1000uF low ESR) which didn't fix the issue. So next I tried connecting the USB cable as well as the Power Supply and all effects including the sound-reactive ones are working. I then unplugged the USB cable and to my surprise everything was still working. Sound-reactive effects are working as expected and I can switch between them, even though the whole system is now powered by the Meanwell PSU. So basically if I "jump-start" the ESP with an USB cable and then switch over to the Meanwell PSU everything works without any issues. After cutting power and restarting the effects won't work anymore. So I ruled any electrical noise issues.

I had a look at the docs but found nothing that could help me. Only interesting thing I possibly found is the initialisation process. My thought here is, that maybe the digital microphone doesn't get initialised fast enough if the ESP is powered via VIN making WLED fallback to analog input (which of course doesn't work).

I haven't tried a custom compiled version yet, my next steps would be to find the mic initialisation in the code and try delaying that by a few seconds to check whether that might solve my issue. Just wanted to run this by you guys before and ask whether you have any ideas / have experienced something similar.

Here is a picture of my wiring if this helps:

Expected behavior
INMP441 working on VIN power input

Enabling Audio Sync - Crashes Network.

Describe the bug
When enabling the feature "Transmit" crashes the network. (potentially flooding), if I disconnect the unit it stops .. connect it again and keeps flooding, brings down everyone on my network.

To Reproduce
Tried changing the Transmit port, same issue even if port 10000 steps apart.

Expected behavior
Transmit should save without crashing the network (probably flooding) and the receiving unit should act accordingly.

Binmap effect doesn't work when receiving UDP Sound Sync

It seems that the Binmap effect does not work when trying to use UDP Sound Sync to receive microphone data. The other effects are working fine. Any ideas what might be going on or anything I could try to fix?

Great project btw!

Reboot every few seconds

I Have a ESP32-Wroom-32, the 38 Pin Version. This one is resetting every few seconds. Any ideas?

I have some normal Wled installations running. Only this one fails with reboots. Its not a bootloop.

WS8215 strip

Hello,
Is WS8215 supported (seems so from the hardware setup) ?
If so, as there is a backup data line .. do I need to connect D4 to both data and backup data lines ?
I dont see a diagram for it on my strip as I had on the 8212B ...

PS: I returned a WS8212B wich was working, but it seems the data does not go to the 8215 as the strip does not react to the changes. The only difference is that now the ESP is connected to the USB port ... might be this or a cable issue.

Lights freezes on OLED display refresh

Describe the bug
When using the ssd1306_i2c_oled_u8g2 usermod the lights freezes for a couple of millisecs every time the OLED display refreshes. Tried with usermod type v1 and v2 too. The refresh rate of the OLED display is also very slow (compared to the non soundreactive version of WLED)

To Reproduce
Change effect or change color palette.

Expected behavior
No hangs and hickups in the light show.

Alexa control

Hello,

I'm using your WLED version with a little mic and it's working well, thank you for the work :)
I was trying to add the strip on my Alexa device to control on/off and static colors, but I can't manage to get it detected by my echo dot.
I was wondering if your project work with this Wled functionality.
I'm able to control another original Wled with Alexa, but the audio reactive is not detected no matter what I try.
I'm running it on an ESP8266.
Thanks in advance for any help.
