Classes & Categories

Any sound in a library is automatically classified & categorized. The result is shown in the results table and can be filtered/sorted, just like any other descriptor.


Any sound in library belongs to one of these two classes:

LOOP - when the sound is found to have a looping or repetitive nature (no category).
ONESHOT - when the sound is non-repetitive (has a category).


When processing a sample, the software will determine how much it matches a(ny) of the built-in categories. There are dozens of categories, divided into Tonal, Percussive and Sound Effects.
