Panaphoria

I made the pack: https://www.gta5-mods.com/misc/british-police-scanner-lspdfr to simulate British MET callouts during LSPDFR. I made a few iterations months ago and they all played fine in game. Recently I returned to creating more voices for plugins, and even resorted to re-recording the entire pack. All of the audio now plays boosted and has become distorted and difficult to listen to, and I'm unsure why. The audio in the pack all conforms to at least -0.3db. The pack has been exported in both 16 and 32-bit WAV files. The only difference I can see is that GTA V uses 16000Hz for its audio files and mine is defaulted to 41000Hz. I'm not sure that this would be the problem since the audio I recorded before was also in the 41000Hz project rate, and it played fine. Is there any fix or explanation that anyone could provide? It would be much appreciated. I will record a sample of what the audio looks like and post it in the comments below.
