Comment (by calestyo):

 Well the sample above seems to work... "tried myself" is here probably
 useless,... HDCD is like some Dolby codecs, i.e. you can play it just fine
 even without a decoder, but you loose something.
 And I personally am definitely not audiophile enough to be sure that I
 really could tell the difference. ;-)

 Apart from that, I think the code from foobar2000 can probably seen as
 kind of a finished implementation.
 I've read through many forums now and that seems to be the conclusion.
 There is that infamous "transient filter" feature, but having talked to
 some experts, this was never ever used in HDCD and there was always only
 one filter in decoding.
