What is a .aup3 file?
The .aup3 file format is the native project file for the popular open-source audio editor, Audacity. It doesn't store the final audio as a single file but rather as a database containing pointers to the actual audio data files stored separately. This allows for non-destructive editing, meaning your original audio remains untouched. When you save a project, Audacity creates this .aup3 file and a corresponding _data folder to manage all your edits, tracks, and effects.

No, you need the Audacity software to open and work with .aup3 project files. They are not designed for direct playback.
The _data folder contains the actual raw audio chunks and other project assets. The .aup3 file acts as a database linking all these elements together for editing.
Technical Details
The .aup3 file is essentially a SQLite database that stores metadata about the audio project, including track information, edits, effects, and pointers to the raw audio data stored in associated .flp files within the project's _data folder. This database structure enables Audacity to manage complex projects and perform non-destructive editing.
