The original pmd100 and pmd200 chips are complicated beasts! I've heard that the non-HDCD filter PMD designed was superior to others at the time (say, Philips or NPC)
Anyone know whether the oversampling filters found inside the OEM pmd100 and pmd200 chips are different from HDCD filter by itself?
That is, in rare devices like the Burr-Brown PCM1732 delta-sigma 96k dac chip, that feature HDCD filtering, is the non-HDCD interpolating filter (that PMD supposedly designed (for use with non-HDCDs) also being used?
When Microsoft software plays back HDCD, does it use the full oversampler?
Bottom line: I'm not interested in HDCD; but just how different companies approach interpolation for common Red Book digital.
