Hi I have made a VU frequency visualiser using a MSGEQ7 chip, WS2812 leds and an arduino. I am pleased with result. I was hoping you could answer a question on how not to degrade the audio. Presently, i run one channel (mono) audio into circuit and have no audio output, and i cant hear anything. …

Frequency VU visualiser.

It would probably help if you say where the audio signal is coming from and what its level is.
