iOS app icon, 1024x1024. A solid bold sans-serif capital "C" filling most of the canvas in pure white (#FFFFFF), opening to the right. Inside the open bowl of the C, a clean horizontal audio waveform in medium gray (#8A8A8A) with 4-5 symmetrical amplitude bars of varying heights — like a tight equalizer reading. The waveform is centered vertically within the C's opening. Background: solid near-black (#0A0A0A) with a very subtle radial vignette darkening toward the corners. Crisp vector edges, balanced, geometric, modern. Premium app-store polish. Strictly monochrome — black, white, and gray only. No color whatsoever. No text or letters beyond the C.

The image shows a black and white icon of a speaker with a sound wave emanating from it, set against a white background.
