Whatever the recording, audio just wants to be heard: the trick is picking a shape that plays where you need it. It comes from wherever your camera, screen recorder or download made it.
OGG is the free spirit of audio: open, patent-free, and quietly brilliant at looping game sound. A container usually carrying Vorbis or Opus audio, both open and royalty-free. That makes it the right destination when what you need is games and open projects that want seamless loops and zero licensing strings.
