## What this tool does
Clean up lecture, interview and meeting recordings — spectral noise removal + broadcast loudness in one pass.

## Typical user problems
- Lecture recordings, interviews and meeting memos pick up fans, keyboards and room hiss. Subscription denoisers (Krisp ~$8/mo) price monthly for occasional use — this cleans one file with spectral noise reduction and normalizes to broadcast loudness (-16 LUFS) in a single pass, pay per file. Your recording is processed for the task only and deleted automatically.
