Audio engineers are the unsung heroes of the live sports broadcast. Subscribe to our channel! http://goo.gl/0bsAjO We don’t often think about audio when we watch sports on TV, but it’s a huge part of the experience. We spoke with several A1 audio engineers who mix the sounds of sports to learn more about what it takes to capture the crack of the bat and the swish of the net. From the cadence of the quarterback to the sounds of skates on ice, audio mixers are tasked with getting microphones close enough to the action to gather the sounds but still out of the way of the players and the fans. Once the microphones are set up, they handle the stressful task of live mixing all the audio for the broadcast, so that we can hear the announcers and the sounds of the game, despite thousands of screaming fans and the PA system blaring music. In the end, if they do the job right, you’ll forget they exist. Vox.com is a news website that helps you cut through the noise and understand what's really driving the events in the headlines.

When you look at sporting achievements over the last decades, it seems like humans have gotten faster, better and stronger in nearly every way. Yet as David Epstein points out in this delightfully counter-intuitive talk, we might want to lay off the self-congratulation. Many factors are at play in shattering athletic records, and the development of our natural talents is just one of them.
