Sounds

Sounds are audio files in the *.OGG format (official specifications). This is a compressed multimedia format with high fidelity for a smaller file size than equivalent mp3/mp4 kbps.

Custom sounds are files located in their own folder in your workshop mod's  folder.

A free, open-source program that can convert to *.ogg from other audio files is Audacity
