I found something. You open Audacity or some other audio editing app and you put in the fail sound and pause loop. You select pause loop, then in the top menu where it says effects, search for invert. Now when the horn goes down in the original audio, it will go up in the current one, so the 2 audio files will cancel each other out and there will be no sound, but when I tried it I realized that pause loop starts to play with a certain delay.
Some time ago I made the comment and I don't exactly remember how much the delay was, it was something around 1.9 seconds, but it turns out that pause loop doesn't sound exactly the same as the original file, so you'll have to record the pause loop, cut it exactly where it starts, so it's the same as the original, put the delay on it and see what happens.
