Final answer:
In the presence of jitter in a digital audio stream, you might hear clicks, which are abrupt sounds caused by the misalignment of data packets.
Step-by-step explanation:
One type of audio artifact you might hear if there is jitter in a digital audio stream is clicks. Jitter refers to the timing variability between data packets arriving in a digital audio stream, causing misalignment in the digital signal which can result in these unwanted noises. Clicks are abrupt and brief noises that can contrast heavily with the intended audio content, making them quite noticeable. In addition to clicks, jitter can also cause other artifacts such as pops, dropouts, and distortion. To counteract jitter-related issues, audio systems need to have proper buffering and synchronization mechanisms.
