Audioreactive question

1

Hi.

I have added an INMP441 and configured WLED.

The sound display sometimes seems “off” in that the strip doesn’t light up in ways I would expect based on the music playing.

I pulled the microphone out while the system was live to swap it with another one for testing purposes.

When the microphone was completely disconnected, the LEDs continued to animate as if there was a sound input.

I need some help confirming what is going on:

Option 1: The PINS being used for the microphone are now floating, leading to the spurious animations. This only happens when the microphone is not attached, and is therefore not evidence of a messy signal causing strange animations when the microphone is attached.

Option 2: This is evidence of interference on the data line. In this case, the interference is present when the microphone is attached, and that would be a reason for the strange animations when the microphone is attached.

Option n: Something else I haven’t thought of (I’m fairly new to WLED).

Looking forward to comments…Thanks

Brendon

INMP is digital, floating pins wont trigger anything.

WLED has a sound simulator which engages when AR is disabled, so check info panel for sound level.

Thanks for responding. To clarify…

I have audio reactive enabled, and the jumper cables running from the ESP32 to the breadboard.

With the microphone inserted on the breadboard, I get animated LEDS, but the animation doesn’t seem to match the music very well.

If I leave AR turned on, and the wires in place, and just pull the microphone out, I still get an LED animation, even though there is no input device.

Do I understand correctly? The AR effect will show a simulated animation when there is no audio input present?

I was expecting that no LEDs would light up if there was no sound

simulation is only activated when AR is disabled.

dont use breadboards, they are unreliable and can cause such issues. solder the wires or use DECENT jumper wires directly.
