We all love seeing data represented in pretty ways — whether it’s necessary or not. Take VU meters for example. They’re a super useful tool for audio editors to balance signals, but they also look ...

A simple audio visualizer that maps the audio signals from ADC to LED strip. The number of lit LEDs is based on the amplitude of the audio signal, with a brighter peak indicator on the highest ...

A real-time audio spectrum visualizer built using an Arduino Uno and an electret microphone module. The system converts live audio into visual LED patterns, demonstrating both signal processing and ...

While high-fidelity audio has come a long way in the past several decades, a lot of modern stereo equipment is still missing out on some of the old analog meters that were common on amplifiers and ...
