In this sound clip titled, "Medium Length Burp", the main focus is on the physiological process of burping which originates from the stomach, or 'estomago' in Portuguese. It begins with a sudden expulsion of air or 'gazes' from the mouth, 'boca', which signals the commencement of the burp. The burp, or 'arroto' as it's referred to in Portuguese, is not short, but of medium length, indicating a considerable amount of air being released. The audio, in essence, captures the natural, albeit a bit uncouth, function of the human body to expel excess air from the stomach through the mouth.
