In Reply to: Is HDCD dynamic filtering possibe at sw level? posted by The Sound Guy on August 18, 2009 at 07:52:11:
The AV receiver contains a DSP, and HDCD decoding is implemented as a library routine on the DSP.
Typically, the decoder implements dynamic filtering by upsampling HDCD to 88.2 (and sometimes 176.4).
The main problem is that there is no software HDCD decoders available for the PC that implements dynamic filtering.
