Si claro is a common Spanish expression that translates to yes, of course, and its appeal as a sound comes from how easily that short phrase flips between sincerity and sarcasm depending on tone. Online, short voice clips like this circulate as reaction sounds for memes, short videos and messaging, where a single spoken line can replace a whole caption. Because the phrase is widely recognised across Spanish-speaking communities, it works even for viewers who only catch the attitude, keeping it in regular use as a quick, knowing reply.
