This could occasionally cause Shairport Sync to lose synchronisation and maybe even to mute for a few seconds before regaining it. It was caused by not doing modulo arithmetic properly, and it's been there for a while. -* Clean up and improve the code to synchronise the first frame of audio. This should result in more accurate and reliable initial synchrnoisation, certainly to under a millisecond in normal usage. Sync should improve even when the silent lead-in time is as short as 0.3 seconds or when the `audio_backend_latency_offset_in_seconds` is as much as -1.7 seconds. -* Removed a bug which would affect initial synchronisation if a flush command was received from the player at an inopportune time. -* Clean up some other uses of modulo arithmetic. -* Clean up allocation of memory for gathering running statistics -- use the heap instead of the stack. +* Clean up and improve the code to synchronise the first frame of audio. This should result in more accurate and reliable initial synchronisation, usually to under a millisecond, and often to within 20 or 30 microseconds in normal usage. Sync should improve even when the silent lead-in time is as short as 0.3 seconds or when the `audio_backend_latency_offset_in_seconds` is as great as -1.7 seconds. +* Remove a bug which would affect initial synchronisation if a `FLUSH` command was received from the player at an inopportune time. +* Clean up some confused uses of modulo arithmetic. +* Clean up allocation of memory for gathering running statistics – use the heap instead of the stack. +* Clean up the display of statistics for backends that do not implement active synchronisation, e.g. the `pipe` and `STDOUT` back ends. +* Add code to flush output to the `pipe` or to `STDOUT` when playing stops.
