iOS app icon, 1024x1024. A bold geometric capital "C" in soft white (#F4F6FA) acting as a viewport or bracket, opening to the right. Passing horizontally through the open mouth of the C: a crisp audio waveform line in pure white (#FFFFFF), with three or four clean amplitude peaks and rounded caps, extending slightly past the C on both sides as if mid-trace. The waveform sits dead-center vertically within the C. The C is rendered slightly dimmer (~85% white) than the waveform to create a tonal hierarchy. Background: solid near-black (#0A0A0A). Subtle white glow on the waveform only. Engineered, diagrammatic, oscilloscope feel. Premium minimalism, vector-clean. Strictly monochrome — black and white only, no color, no gradients other than the soft glow. No text, no letters other than the C, no numbers.

The image shows a black and white logo with the letter 'C' in the center, set against a white background.
