SDMI Watermarking Effort Rankles Engineers
The <A HREF="http://www.sdmi.org/">Secure Digital Music Initiative</A>'s move to establish a copy-prevention technology for commercial recordings has rankled audio engineers, who claim that the audible watermarking technique chosen by the organization could mar high-resolution recordings. Of particular concern are SDMI's testing methods and its rush to get a standard in place without commentary from engineers or the music-buying public.
