ok, you can make the systems "in-sync" with PTP. but are there audio
interfaces that can use the clock from the host? i.e. the host drives the
audio interfaces clock.
Hi, i'm following the thread of the ongoing
topics around transmitting
audio over IP infrastructure. As a scenario, at point a) an analog signal
is injected that will be played back (analog) at point b) with the
lowest possible (and constant) latency. How do you intend to handle
diverging clocks of the audio interfaces (ADC/DAC) at both (a/b) ends?
AES67 (and other formats) use PTP (IEEE 1588-2008) to keep the system
clocks aligned at a usec level. The media clock is then derived from that.
The media clock on both systems should therefore be syncronis.
