The Great Mystery of Project Title vs Audio Title

According to the Official Dalet 5.1 User Manual:
"A project file is simply data that points to existing audio material stored on the system's central server. It is not the actual audio." Projects are simply the changes you make to the Audio Title that is already saved in the system.

The two types of files are based upon each other. The Audio Title is the basis for all data stored in Dalet. The Project Title identifies for the database all of the changes a user makes to an Audio Title. If the originating material (Audio Title) is deleted, the Project Title (or the changes the user makes to that specific Audio Title) will become useless.

Below is a comparison table that shows the major important differences between a Project Title and an Audio Title.

Project Title (EDL)
Audio Title

Projects look like this in the Base Browser and are sometimes called EDL files which stands for Edit Decision List.

 Audio Titles look like this in the Base Browser

IMPORTANT: Projects (EDL) SHOULD NEVER be placed in a conversion category for conversion to MP3/RA (this will cause a malfunction in the Interweb for the whole agency and IDAPS support will have to be contacted immediately to reset the Interweb).

 Audio Titles ONLY can be placed (via secondary category save) in a conversion category for conversion to MP3/RA.
Projects (EDL) are NOT digitized audio. They are the changes and pointers to an audio file. If the originating audio material is deleted, the Project Title becomes useless. An Audio Title is the actual digitized audio file as it was recorded or transferred.
Saving as Project Title saves faster than Audio Title because there is no audio contained in the file to convert for dalet storage. Saving as Audio Title can take more time because the audio needs to be converted before storage in the Dalet system (this is the reason for the blue progress indicator when saving).
You may save as a Project Title only after the audio title has been saved. (In the case of Surfer, it is saved while recording. In the case of Recorder, you must click Current Channel, Save or Save As...) The Audio Title is saved when using Surfer for recording. When using Recorder to record, you must click Current Channel, Save or Save As... to make the Audio Title. Projects cannot be saved or created with the Recorder.
When working on an audio file making changes, if you Save as Project Title, your changes will be retained for later access and modification. If, after changes are made to the file, Save As Audio Title will be create a whole new audio file with the changes incorporated. You will not be able to open the file later and alter your changes that you have made before Save as Audio Title. You will see the file without any user changes, with the last user changes implemented.
