Re: [Savonet-users] input.harbor problem

[David B. <dav...@gm...>]

Hi,

I may not have enough details in mind, but I don't see why you should
bother starting/stopping the white noise generator. It usually
suffices to put it in a fallback (instead of mksafe) so that white
noise kicks in instead of silence. Don't worry about when the
generator is useless, it won't compute anything while unused for
streaming.

Cheers,

David
