"Keith Howard (of HFN and Stereophile) authored the invited lecture 'High Definition Audio, How is it delivered' and he succinctly and unambiguously exposed the cynical attitude of some record companies and their supposed HD audio releases by analysing their spectral content, their bandwidth and peak levels via a computer, rendered much easier than for previous work by the digital nature of the recordings themselves. Those music data numbers may be crunched to find out what the tracks are made of. He found that some HD releases, both DVDA and SACD had plain CD content, i.e. the CD layer and HD layer were the same lower resolution, while no labelling was present to help the purchaser decide. Keith indicated the he also suspected that in a very few cases hybrid discs were rendered with a CD layer of lower playability (e.g. reduced pit contrasts) so that this layer would play with reduced fidelity relative to the primary SACD layer. His analysis showed other unwanted manipulations including re-sampling, and a failure to go back the analogue master for an HD release when a wide bandwidth analogue master was available as a source. Fortunately a few specialist audiophile HD discs were found to be of genuinely wider bandwidth and quality."
