For my purposes that won't work, because I won't control the other party's microphone, which is the one whose recording is expected
to be altered. I might make my own recording that could be compared with the other, and mine, having a watermark, would be more
credible, but I could be accused of adding the watermark afterward. The solution I envision would add the watermark at the source,
my voice, not the pickup, the mike, and therefore to all recordings using anybody's mike. It would be pervasive throughout the room,
including for any paraboloid mikes across the field.

For this, you have to think spook. What would Tom Clancy's characters need?
