Phase 10 workflow: browser-first processing where possible; live data tools call the same-origin NovaTools proxy and use TTL cache plus fallback messaging.

How this tool works

Create a local waveform preview from an audio file with the Web Audio API. The tool is designed as a premium workflow page with clear input, status, result, and privacy/error states.

Privacy and data handling

Local analysis stays in your browser. Live market and weather data requests go through the NovaTools proxy so API keys and upstream URLs are not embedded in page scripts.
