My apologies about the audio, to explain, in OBS I recorded the game audio through both my capture card AND through my microphone (if that explanation makes sense, I have the audio running through "Video Capture Device" and "Mic/Aux" basically). Now, in recording my capture card I've also noticed a tendancy for the audio to gradually desync over time. So, essentially in this run, there were two streams of audio, one was of the run live as it was happening, and the other was the desynced audio running concurrently, that's why the audio sounds the way that it does. Since the run's audio is still there and at least one of the two streams can clearly be heard synced to the gameplay I'm hoping this is still verifiable, my apologies to the verifiers if this is a pain though.
