Graphic Equalizer
A hi-fi spectrum analyser with 28 LED columns, peak-hold markers and a kick on every beat. Push the bands up with your pointer.
What you're looking at
No sound is playing. Each column's level comes from two layers of noise, one slow and one fast, tilted so the bass runs hotter than the treble, plus a pulse twice a second on the lowest bands to stand in for a kick drum. A small marker holds each column's recent peak and falls back slowly.
The idea behind it
Real analysers split the signal with a bank of filters, one per column, and drive the LEDs from each filter's output level. The green, yellow and red zoning comes from recording practice: green is comfortable, yellow is loud, and red means the signal is about to clip.
Try this
Move the pointer over the bands and upward to boost them, as if riding a slider.
