Here, the area you cannot skip is the Capitol. Capitol is the seat of the House of Representatives and the Senate. The huge dome, on the basis of the dome of St. Peter's in Rome, stands apart especially different Washington buildings.
Dynamic range compression (DRC) or simply compression is a signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds by narrowing or compressing an audio signal's dynamic range.
This way, you only hear the effects of compression and not the unhelpful change in volume, which can trick you into thinking that because the compressed signal is louder it's 'better'. This is a good way to maintain sonic integrity when adjusting dynamic range through compression..
