I have one app where the audio is ahead of the video, so I'd like to delay the audio for half a second. I'm currently redirecting the app's audio to a pulseaudio null module, and then using parec to send the monitor output to an external buffering program, which then outputs the data half a second later back to pulse. Is there an easier way within pulseaudio to do this?

The loopback module will allow you to add up to 2 seconds of delay between a source and a sink.
