How to Create Custom Horn and Bell in TSW?

[LuFeDuTi]

Hi everyone, how are you? I hope you're all doing well. I have a question about creating custom horn and bell sounds in TSW. I know I need to use the same filename, but even when I try to edit the sounds in the simulator, the old ones keep playing. I don't want to use Unreal Engine because I only want to edit sounds, not do full editing, and I don't know if the sound file format is OGG or WAV. Did someone try to make a sound and it worked, or did they watch a tutorial on how to do it and it worked for them? To extract the files I use fmodel and to convert them to a pak I use unrealpak-main
