Hi Adrian
Hi!
Let me CC Robin and LAD on this one.
Hope you don't mind me contacting you directly, but I have a
question regarding the RME TCO option and how it is supposed to
work. I saw your name on some ALSA commits relating to the TCO
recently and thought you would at least be the right person to start
by asking.
The TCO can read ltc, but once it has done that how does it
communicate that time information tothe user space ? If I was, say,
running Ardour and wanted it to chase this ltc what would Ardour
need to do to make use of it ?
can't say how you get at the TCO input, but thanks to robin's recent
work, ardour can chase an incoming smpte ltc signal. it is just another
audio signal, connected to ardour's ltc input port.
fwiw, you don't need a TCO to chase LTC at all. the TCO is interesting
if you want to generate LTC in hardware, or if you want to _sync_ to
LTC, i.e. recover a clock signal from it.
