So i found out how to break the sound feature on scratch. I only think this works on the “pop” sound so yeah. First get the pop sound from the sound library. Then start slowing the sound down a bunch and when it is very slow turn the volume of it down by pressing “softer” a few times. Then speed it up and start pressing louder and you can infinitely louden it i think.
Headphone warning. I might be wrong. Space for loud pop. Try loudening the pop sound in the background sounds.
