An introduction to computer audio
A very fast way to find your audio is using the search box.
If I type beet kemp I get all the Beethovens played by Wilhelm Kempff.
If I type -beet kemp I get all played by Wilhelm Kempff but no Beethoven.
By default a couple of fields are used for the search operation.
In Tools > Options > Libraries & Folders > Manage Fields you can select each field to in/excluded it from the search including your custom tags.
The Wizard allows you to formulate rules.
This one selects all files without embedded cover art.
You can also type the syntax manually in the search box.
