I am using Rivendell Radio Automation and we have towers in Eastern,
Central and Pacific timezones.
We have one master output for all stations. Management wants the
output delayed for each timezone so that for example 9am content airs
at 9am in each timezone. Content is mastered for Eastern timezone and
simply needs to be delayed one hour for Central and three hours for
Pacific.
I temporarly have Rotter setup recording one hour slices of the master
output and Mplayer on a cron job playing the correct slice for the
respective timezone. BUT there is a small break when Mplayer finishes
the one slice and starts the next - which we want to avoid.
I was thinking that if a delay plugin could be created that stored a
max of four hours (not just four seconds) that this would be smoother.
as has been noted, this involves very large amounts of memory (plugin
delays don't write to disk in general).
i don't know rivendell, but if was doing this with playlist-based
software i'd simply set it up using a playlist with 0,1,2,3 and 4
hours of silence at the start of 4 different playlists with the same
material in each. no memory utilitization, no disk utilization. i
don't know if rivendell can do this but i'd be a bit suprised if it
could not.

tried that and it still makes an echo by mixing the delay back
with the original.
If you could give me the exact plugin name and exact settings that do
work I would appreciate that.
I have two different sized delays that I need to
create.
1.) I need a audio delay of no more than 4 seconds. All of the delay plugins
for Jack-Rack create echo. I just need a pure delay or artificial latency
inserted into the jack audio stream (the output needs to be delayed 4
seconds from the input without mixing back the input).
just change the dry/wet mix to 100% wet and you'll get what you want. 2.) I
need a timezone delay of no more than 4 hours. (there are no plugins
for Jack-Rack that do this and my attempt to create one with csladspa
doesn't work... I have plenty of hd space for looped storage.)
more details on the use case would be appropriate. it may not be that
a delay in the conventional sense is the right answer. or it could be.
no way to tell.
