VSCode Audio Visualizer Extension

A VSCode extension that visualizes system or microphone audio using multiline cursors, turning the editor into a music visualizer. Perfect for developers who want ambient music visualization while coding without leaving their IDE.

Developer tools that double as ambient or aesthetic experiences have carved out a genuine niche, driven partly by the Twitch/YouTube coding-stream culture where visual setups matter and partly by the broader "developer experience" movement that treats the IDE as a personal environment. No clear incumbent exists in this exact space, though extensions like Peacock and Power Mode show that purely aesthetic VSCode extensions do convert to paid users. The $500–2k/mo ceiling makes sense only as a one-time purchase or small tip-jar model, since subscription justification for a visualizer is a hard sell and the audience skews toward free. The most likely failure mode is novelty exhaustion — it's a screenshot-worthy demo that most users uninstall within a week once the curiosity fades, leaving no retention hook to monetize against.
