AirPlay 2 -- More About What Works
---
* Two types of audio are received by Shairport Sync -- "Realtime" streams of CD quality ALAC (like AirPlay 1) and "Buffered Audio" streams of AAC stereo at 44,100 frames per second. The selection of stream type is made by the player. Realtime streams generally have a latency of about two seconds. Buffered Audio streams typically have a latency of half a second or less.

Note
----
The functionality offered by Shairport Sync is the result of study and analysis of the AirPlay 1 and AirPlay 2 protocols by many people over the years. These protocols have not been officially published, and there is no assurance that Shairport Sync will continue to work with AirPlay in future.
