Method sync

src/client/callbacks.rs:115–122

For slow-sync clients, called periodically when the transport position is changed. The transport will not start rolling until all clients indicate they are ready, or a timeout occurs. It should return `false` until the handler is ready process audio. Ignored unless Self::SLOW_SYNC == true.
