I have 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 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.

Thanks,

Daniel
