I first laughed about calibrating sound systems with microphones to compensate for different cable lengths until a sound engineer let me listen to the differences.&lt;p&gt;He could hear if a box had a delay about 2-3ms. Quite hard requirements.</text><parent_chain><item><author>bonniemuffin</author><text>I wish there was a good way to sing together over videochat. The lag makes it impossible--if you&amp;#x27;ve tried singing Happy birthday to someone over Zoom, you&amp;#x27;ve probably noticed that it&amp;#x27;s the worst! Everyone tries to adjust to everyone else&amp;#x27;s lag and it just makes everyone even more and more out of time with each other.</text></item></parent_chain></comment><story><title>Singing is the most accessible stress reliever</title><url>https://www.bbc.com/future/article/20200518-why-singing-can-make-you-feel-better-in-lockdown</url></story>

Some choirs use instructions like &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.makingmusic.org.uk&amp;#x2F;resource&amp;#x2F;zoom-online-rehearsals-vocal&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.makingmusic.org.uk&amp;#x2F;resource&amp;#x2F;zoom-online-rehearsa...&lt;/a&gt; where everyone is on mute and can just hear themselves and the choirmaster.&lt;p&gt;I think a technological solution would exist: A and B hears choirmaster, A and B&amp;#x27;s sound is sent back to server which syncs it with the choirmasters sound before sending to C, D, E and F. C, D, E and F&amp;#x27;s sound is sent back to the server which syncs it and  sends to G, H, I... etc.&lt;p&gt;So most people can sing along hearing some of the choir and the latency overall shouldn&amp;#x27;t be too bad. Scales with log(n) * max(latency)</text><parent_chain><item><author>bonniemuffin</author><text>I wish there was a good way to sing together over videochat.
