New high resolution SACD releases, players and technology.


I appreciate all of your work in putting this information together. Definitely an interesting puzzle. The thing that has me scratching my head is the application of an apodizing digital filter to the "CD-res version" of the Beyonce album. This is a no-no, according to Peter Craven's original paper describing apodizing filters:

"We suggest that the final digital to analogue conversion may be
the appropriate place for the apodising filter."

That is from the summary conclusion. Earlier in the paper is an entire section explaining the reasons for the end of the chain as the optimal location for the apodizing filter.

As always, strictly my own opinions and not necessarily those of my employer or minister.
