7.5 The Metadata Editor

7 THE PRO-CODEC MANAGER APPLICATION

The list of presets is ordered alphabetically, and is immediately re-ordered when a new

preset is saved. Empty presets cannot be saved, so the

+ button is not displayed when

the

Metadata Editor is empty.

To delete or remove a preset, hover your mouse cursor over the preset name, and press

the red

X button that appears at the right-hand side of the row. A pop-up window will ask

for confirmation before deleting the preset.

7.5.9 The Metadata Lock Mechanism

It is important to remember that the changes performed in the

Metadata Editor are not

written to the selected file until the

Write to File button is pressed.

If a new file is selected for processing when the metadata of the previously selected file
has been edited (but not written to file), those changes will be lost. A pop-up window will
appear in this case, to warn the user and allow the operation to be cancelled.

Each field in the

Metadata Editor can be protected to ensure that it isn’t modified during

editing. Clicking at the beginning of that field’s row, in the padlock column, will toggle a
small padlock on that row.

Click and drag in the padlock column to lock or unlock multiple tags.

Locked rows will retain the current tag content when clearing, reverting, or importing
metadata from other files or presets. Additionally, when changing the
selected-for-processing file, that row will keep its state. The

Cover Art tag can also be

locked, by clicking on the padlock icon in the lower right corner.

When a non-encoded file is selected for processing, metadata info can also be added in

the

Metadata Editor. The main difference with encoded files is that the Write to File

button is disabled, since this metadata cannot be written to an uncompressed PCM file.
Instead, the metadata in the section will be written to the new encoded file.
