Modulators node
Audio Analyze
Listens to any audio and splits it into 8 frequency bands plus a transient onset trigger — the node that lets visuals genuinely react to music, band by band, hit by hit.
What it does
Audio Analyze is a modulator: it makes a moving value that can drive any control on the canvas. It takes audio in and gives control signal out.
Try it
Route a bass band into the Ocean node's amplitude so the sea pulses with the low end.
