Convert Zoom to a radio channel


The other day I went to a Zoom Postcard Campaign writing party. About 40 people attended the event, and they were a lively and entertaining group. But what I found most interesting in the afternoon was that at one point our Zoom room doubled as a radio station.

There we were, all busy writing postcards to voters’ addresses given to us, and suddenly Gil Scott-Heron’s “The Revolution Will Not Be Televised” began to come out of our computers. As the music continued, I asked the host how she did this.

“Well, I’m just playing my speaker into the laptop’s microphone,” she replied.

It sounded pretty good for such a simple arrangement. I guess another way would be to go to “share screen” and then check “share computer sound” and then play a Youtube music video – or something like that.

Maybe at some point Zoom will offer a background music feature similar to its “choose virtual background” option in video settings. Until then, an external speaker or “sharing computer sound” seem to be good options.
