What protocol is used to synchronize Dante devices across the network?

The correct answer is PTP (Precision Time Protocol) because it is specifically designed to synchronize clocks throughout a computer network with sub-microsecond accuracy. In the context of Dante devices, which involve audio streaming over Ethernet, precise timing is crucial for ensuring that audio streams are delivered without latency or synchronization issues. PTP allows Dante devices to maintain accurate timing across the network, which is essential for applications requiring high precision, such as live sound reinforcement and broadcast.

NTP (Network Time Protocol) is used for synchronizing time across devices but does not provide the same level of precision required for audio applications. While SMPTE Time Code and Word Clock are used in audio environments, they serve different purposes, such as managing time code for film and video or syncing digital audio devices, but they are not protocols for synchronizing a network of devices like Dante does. PTP's focus on high-resolution synchronization makes it the ideal choice for Dante networks.
