## What this tool does
Add natural echo depth to dry vocals and instruments — four spaces from bedroom to cathedral.

## Typical user problems
- Dry phone and DAW-bounce recordings sound flat and close — the voice sits on top of the track instead of inside a space. Four tuned echo spaces (room, small hall, large hall, cathedral) give the recording real depth without installing a DAW, delivered as a share-ready MP3.
