Length of Heardle Audio is 9 seconds instead of 16

Hey, you guys! So I’m working on a Heardle for one of my favourite bands and I was wondering, when I preview the website, the audio is only 9 seconds long for guessing the song. Someone else’s Heardle has a 16-second audio length instead of 9 seconds. Is there a way I can change my preview audio from 9 to 16 seconds? I use soundcloud links and not audio files. I’m new to coding and not sure how to fix it.
