I'm guessing you missed the reply to your first message:
...but it wasn't very helpful because it points you to the gigantic,
monolithic help file variant and to the video waveform monitor filter
which is not what you want.

See showwaves and showwavespic filters:

If it must "slide" you can use showwavespic filter as the foreground,
color filter as the background, and overlay filter to slide it.

Non-subscribed users do not get direct replies so I CC'd you. See the
archives (via my first link) to see if there are replies by others.
