The GX9000 uses the term Project to describe a file that contains information that can be used to
configure the unit and to control playback. Most commonly the file will be an AES31 style Audio
Decision List (ADL). These ADL files have the extension .ADL and can reference many other mono
files.
The simplest project file is a mono audio file. The data in the audio file header tells the machine what
sample rate and bit depth to select to correctly playback the file and the file’s timestamp determines at
what time-code the audio will be heard.
By contrast an ADL project file can contain a long list of events, will reference many other audio files,
and will probably reference other meta-data files which hold relevant information. The rest of this
section will refer to ADL Projects
The GX9000 can generate two type of ADL Project. The standard AES31 ADL Project will be
generated if the unit is dropped into record using the AES31 File Format in PCM mode. A modified
version of the standard ADL Project will be generated when recording in DSD and is selected through
the AES31DSD File Format. The diagrams below illustrate the differences in the ADL formats.
How Do I Create a Project?
You don’t have to. The recorder automatically creates a project for you when you drop into Record
with some tracks in record ready. That’s unless there is already an ADL Project open in which case
the recorder will automatically add information to the open project file every time you go into record. If
you close the project, then the recorder creates a new one the next time you go into record.
If you use the GXR remote control software, it is possible to define a default project name that is used
as the basis for all folder and ADL names. This obviously aids locating projects on disks containing
several.
The diagram below illustrates an example file hierarchy with four folders generated from four different
recordings. Note that to generate the new folder the previous *.ADL file must be closed by pressing
the
Enter
button while the Open menu heading is displayed, or the record mode set to New ADL.
