Is there a name for this?
Certain types of recorded audio have this condition where it is as if there is really deep low frequency bass being played, and it is causing all other audio frequencies to be muted during the low frequency pulse.
As the pulsing continues, the higher frequencies are repeatedly muted, loud, muted, loud.
It seems like an attempt to simulate "thumping bass" with tiny high frequency speakers that do not have the capability of actually producing a low frequency sound wave.
Apparently the best example is an audio sample. Here is a Youtube video exhibiting this audio at starting at 1:16.
