How do you intend to handle diverging clocks of the audio interfaces
(ADC/DAC) at both (a/b) ends?
Either
1. Sync the HW sample rates to an explicit or implicit reference
provided by the network protocol. Requires special audio HW.
A few normal audio interfaces (e.g. some RME cards) would allow
to do this as well, but I know of no software that uses this
capability.
2. Resample at the receiver, as njbridge does.
3. Use some other trick. E.g. for VOIP a classical one is to
modify the lenght of the pauses between words or phrases.
