Use fifos. An example :

-------
!/bin/sh

ADELAY="-delay 0.5"
AQUALITY="-q 5"

rm -f audiodump.pcm ; mkfifo -m 600 audiodump.pcm
mplayer $ADELAY -quiet -vc null -vo null -noframedrop -ao pcm -nowaveheader $1 &
oggenc --raw --raw-bits=16 --raw-chan=2 --raw-rate=48000 $AQUALITY -o audio.ogg audiodump.pcm &
wait
rm -f audiodump.pcm
-------

Other solutions are available. The latest ogmtools can delay audio
tracks very easily while muxing for example.
