Just came across this story Here on using watermarking for serving ads. The company has a Website that claims (under topic of Our Watermark) that it is "invisible to all forms of audio analysis".
Anyone have any comments about this?

If you have access to the original as well as the watermarked version, all you have to do is subtract the two in an audio editor and you will see (or hear) that they are not identical. Does this qualify as "audio analysis"?
