Source node
Audio Texture
Turns an incoming audio signal into an image, rendering either a live Waveform or a Spectrum (FFT) view into a GPU texture, with adjustable FFT window size and smoothing.
What it does
Audio Texture is a source node: it makes a picture from nothing, so it sits at the start of a visual chain. It takes audio in and gives picture out.
Try it
Feed a bassline in using Spectrum mode with high smoothing for a slowly pulsing frequency-bar texture to layer under other visuals.
