Well. In short, I found that I must add that converter in above thread provided to make the detect works. Really hope Apple could provide a sample project about how to create a buffer from music file for ShazamKit. Here is the question I posted, and for details you could go to (there)[https://stackoverflow.com/questions/69506460/shazamkit-music-detection-session-matchsignature-with-no-match-found-and-no]

Hi danieldty, No! It has affected many automated tests in our business app. It happened in our iPhone 13 Pro and iPhone 12 both. Although Apple didn't give me any feedback on this issue, shame it. We are paid developer, and they don't give a shit, this forums is like zombie zone. I'd not come back again.
