I've never seen any. The amount of work to develop such a thing
would depend on your exact requirements. Important parameters
are:
* Which operations should leave the watermark intact. If this
includes lossy encoding/decoding things get more difficult.
* The minium duration of a fragment that allows the mark to be
detected.
* How strong the 'provability' should be.
* Operational requirements. For example, should it be possible
to verify the mark without having the information necessary
to remove it ?
