Applause is hard to capture very well. Often times the microphones capturing the applause are a far distance from the rest of the capture electronics, and depending on the equipment you're using, that distance can have a pretty severe affect on the quick transients that make up applause audio. Then take that and put it in what really is a badly compressed audio stream - which it undoubtedly is, and you get mush. Because of the transients and broadband nature of applause, any lossy codec has a hard time encoding it. By the time it reaches the end consumer, the audio and video have undoubtedly gone through several rounds of codecs (encode/decode), which further aggravates the issue.
Yeah.
It's an artifact from repeated lossy compression.
The audio/video is being streamed to studio or a mobile-studio (a van); from there to network/cable broadcasters and affiliates; and then it's sent to the cable companies where it's compressed a final time to travel over cable to your TV.
At each step, on route, it loses fidelity. Audio gets "tinny" or "holllow" from repeated lossy compression.
You can reproduce the effect by transcoding an audio file several times between high-and-low bitrate MP3 and AAC.
