Common Time, Without Sending the Music

Editorial interest 84/100 Selection signal · not a rating of the site

A protocol for synchronising pre-loaded audio across independent devices using anchors, integer ticks, and transport commands.

Landing page captured for the 2026-09-15 issue.

Field notes

Common Time keeps the media local and sends only synchronization information: an immutable anchor, integer ticks, and transport commands. The specification divides the system into ten messages and five operations, with explicit obligations for implementations. Its numerical boundary is unusually concrete: ticks must remain within 53 bits, a constraint the page connects to JSON floating-point handling and a stated 151,000-year horizon at 118 BPM.
