Build

cmake -S . -B build
cmake --build build

Notes

The editor writes metadata directly into the audio file rather than using JSON sidecar files.

On macOS, the app uses the native global menu bar and keeps file actions there instead of duplicating them in a second top toolbar.

Recent paths are stored with QSettings, so they persist between launches.
