[LAD] media clock from wall clock

2014-10-12 Thread Len Ovens
I have been playing with numbers (a little) for AoIP and AES67 (because I can actually read the spec). The media clock (AKA wordclock) is derived from the wall clock which is synced via PTP. There are 3 sample rates supported 44.1k (not sure if any physical devices really do), 48k and 96k.
