Sound Wave Waveform Line Pattern

A single horizontal continuous black ink line on a pure white background tracing an audio sound-wave waveform across the frame, the line oscillating in varying amplitude with sharp peaks and soft troughs, a tall initial attack transient on the left decaying into a steady middle sustained section and a long fade-out tail on the right, even thin black ink, no shading, no color fill, no axis, no grid, no labels, no text, no letters, no numerals, wide 16:9 composition Art direction controls: deep cobalt, warm cream, and charcoal, a centered hero composition with deliberate negative space, quiet and editorial.
