As the audio titled “Brief Belch” starts, a sudden, short, and sharp sound, akin to a burp, fills the air. It's a very distinct sound that is often associated with the release of gas from the digestive tract through the mouth. The sound is brief and to the point, with no additional noise or background sound. The audio clip is concise, ending almost as quickly as it begins, leaving an impression of a quick, sharp burp.
