You can use the "-t:seconds" option for specifying processing
time ('seconds' need not be an integer). This should do it. 'at' and
'cron' will handle the rest.

Well, with ecasound (and other programs using libecasound), file size is
no problem. Only thing you have to be worried about is your kernel
