Universal's Audible Watermark (2012)
>I don't think there is anything inherently wrong with watermarking. The problem is with this particular poorly tested implementation.<p>There is. Audio watermarking is <i>inherently</i> audible, because that is the only way to avoid being stripped out (deliberately or inadvertently) by the incredible technology we have for removing inaudible information from audio recordings: lossy audio codecs. The artifacts must be so salient that the codecs deem them important, audible information - codecs designed with elaborate psychoacoustic models, especially to make that judgement call with maximum efficacy. There's no way out.
