The audio stream is often divided into chunks and interleaved with the
video stream. -audio-density determines the size of those chunks.
-audio-preload determines how much audio to buffer before starting
video playback.

As far as I know these options shouldn't affect sync unless the audio
chunks are so big that they can't be stored until it's time to play
them. Of course some video players are very sensitive to non-standard
settings so you might have a problem if you pick sufficiently weird
settings.
