HDCD Decoding on playback

[Esskay]

About 15 years ago, someone deconstructed Windows Media Player and reverse engineered the HDCD decoder component. That became the basis for the hack hdcd.exe, which then became the basis for open source decoder solutions in foobar2000, ffmpeg, etc.

The patent infringement and trademark protection legality of the reverse engineered hack and subsequent open source implementations likely is questionable. Roon probably will not tread down that murky path.

This is the code I referred to in the other thread: HDCD Playback decoding. But the Reference Recording people claimed it didn’t work properly. They didn’t voice concern over violating anyone’s rights (perhaps they don’t care).
