can hide date in an audio file and it NOT cause some

Hiding data in WAV files or similar is fairly simple. It's a bit
more difficult in lossy formats but still not rocket science.
But a watermark needs more than hiding:
* It should survive a change of format.
* It must not be easily removable unless you have
privileged information.
And that can be quite hard.
