Radio/TV broadcast analytics is the most frequent use case. At least I receive a significant amount of questions regarding it, so the library has been optimized for this task. YouTube ads detection is also an interesting case that falls in this category.

Other use cases are divided between game development, repeating content detection, robocalls detection, or just iOS/Android apps for Shazam like style features.

Surprisingly a couple of times, I was asked about recognizing birds by their singing. The library can't do it, but it is something I am thinking about exploring one day.
