Comment (by cyclonus):

 Sorry, I would've replied earlier, if I had received any e-mail
 notification.

 For what it's worth I had to resort to 'dd' for creating a short sample.
 The fine tool 'Audacity' corrupts audio samples - at default settings -
 even when loading a WAV file and exporting it as WAV file. The resulting
 file didn't contain any HDCD information due to the modified samples.

 The HDCD utility provided was apparently written by Chris Moeller (author
 of Foobar), Nick Gorham and Jim Lesurf. The license statement from the
 tarball is attached.
