Emma Baccellieri, Sports Illustrated:

When MLB settled on its structure for coronavirus gameplay—in home stadiums but without fans—it knew it would need to provide a remedy for the unnatural quiet of empty ballparks.

The league found its answer in the form of 30 iPads, one for each team, loaded with various crowd reactions so that a little tapping and scrolling was all it took to play the proper noises. But an artificial crowd is as an art as much as it is a science. And it’s harder than it looks (or sounds).

The linked SI article is from back in September. I had no idea how this was done. And, frankly, I’m glad. It does take away a bit of the mystery.

But, that said, this is pretty cool. Wondering if other sports use the same approach. The NFL has famously adopted Microsoft Surface (that first season, cameras caught a lot of coaches using iPads, NFL clamped down). Wonder how they do it? Well here ya go. Don’t miss that Mac screenshot at about 1:34.
