# Detect Repeated Audio Sections

The most straightforward use of the AFP functionality is to build up a database of clips, and then search for those clips in unseen audio. However, there are other ways of making use of AFP functionality. For example, you can search a large collection of audio data for repeated sections, to help to identify features such as jingles, recorded messages, or adverts.

To detect repeated audio sections

1. Index all the audio data into the AFP database.
2. Perform AFP identification across all the data.
3. Look for any matches that are not from the same location in the same file. You could narrow your search by considering sections over a certain length, and that are matched in other locations within the audio data.

HPE IDOL Speech Server cannot directly identify repeated sections that meet your criteria, but it does provide the underlying AFP identification results from which you can determine such information.
