Okay, I want to make a horn sound for a custom locomotive. It is a Leslie 3-Chime Super Typhoon. I have audio files from a video except there is one problem, I need to shorten the video to only play the 4-5 second horn sound.
Can someone tell me how to only get that part of the audio, and also how to export it into trainz?
