The plug-in only partially reproduces the full HDCD decode. If the Cary does the whole process you may be better off turning off the foobar decoding. As Larry says, that should let the original signal pass to the Cary and the Cary can do the proper decode.
HDCD FLAC FOOBAR SPDIF Cary 303/200 HDCD
Im trying to play HDCD encoded files to My Cary 303/200 but they dont seem to be recognised bythe Cary as such. Im Using the HDCD plug in for foobar. When i put in an HDCD CD the HDCD light comes on on the Cary. However when i run the ripped file hrough the spdif into it the light doesnt come on.
Not sure if its just not passing the hdcd signal(set at 24bits/96khz default in HD Audio manger, at 16/44 doesnt help get hdcd) or if the Cary will only recognise HDCD from a disk.

Here is some more explanation of the HDCD encoders in foobar (and other software implementatons) and why it is not as good as the original hardware implementation. The 16 to 20 bit extensions are done, but the digital filters are not implemented in the software versions. The Cary 303/200 has the original Pacific Microsonics chip, so should be better than the software implementations. From the person who wrote the HDCD decoder in foobar "only gain and peak extension are applied. Transient filter is not supported, as there is no reference software to base the filter on. Besides which, the transient filter is really only useful if you're also upsampling the output to 88200Hz, or at least so I've heard." Quote from hyrogenaudio thread, post 97 of this thread foobar HDCD discussion on hydrogenaudio From Goodwins High End website "Every CD player has a digital filter that is an integral part of its sound reproduction electronics. In addition to decoding HDCD recordings, the HDCD decoder chip used in consumer products also contains the HDCD high-precision digital filter that improves the sound quality of all types of digital audio recordings." |
David256 - read my comments above. dBpoweramp uses the same code as foobar. It does part of the job of the old Pacific Microsonics chip, but not all of it. A DAC with the old chip will do a better job of reproducing the original HCDC sound than the software solutions. Helian's point is important and needs to be checked out. |
