AI Voice Assistant Waveform Loop Black Overlay 4K Vertical - 4K 影片檔

An AI voice-assistant waveform on pure black: overlapping cyan, blue, violet and magenta lobes drawn with fine contour lines swell with each syllable of three spoken phrases, then settle to a breathing line with a gliding glint in the pauses. It follows speech rhythm, not a beat, so it sits under dialogue. The background is true black (#000000) from edge to edge, with no vignette, gradient or grain: set the layer to Screen or Add and only the light stays over your footage. Seamless 15-second loop, no text. Vertical 9:16 cut for reels, stories and phone screens.
