In the manpage it is said:
−audio-delay <any floating-point number>

Delays either audio or video by setting a delay field in the header
(default: 0.0). This does not delay either stream while encoding, but
the player will see the delay field and compensate accordingly.
Positive values delay the audio, and negative values delay the video.
Note that this is the exact opposite of the −delay option. For
example, if a video plays correctly with −delay 0.2, you can fix the
video with MEncoder by using −audio-delay -0.2.

Currently, this option only works with the default muxer (−of avi). If
you are using a different muxer, then you must use −delay instead.

Hope it works...
