HOW TO AUDIO-CANCEL

It's not that hard;

Context you can skip if you dont care:

(Nobody asked a single question about my speedrun probably because nobody cares, but this is how I achieved my times)

Quick note:

This might only work on Windows.

Step 1:

Grab a controller that your PC recognizes as an audio output device.

Last step:

Plug a USB cable that's connected to your PC into the controller. This will stop any audio playing in game.

Why this works:

I don't really know but I assume it has got to do with how Unreal Engine handles audio devices and audio playback.

What I know:

The audio playback gets stopped which the game recognizes as the audio track to be complete, prompting the game to continue with what should happen after the audio is done.

In short:

The game doesn't rely on a timer for it's cutscenes but instead on if the audio has ended, which we can exploit by stopping the audio and therefor the cutscene prematurely saving us time.
