HDCD / Dolby ProLogic ripping

[dt2510]

i have a few Audio-CDs having the HDCD logo (20bit data encoded in a 16bit stream - look here http://en.wikipedia.org/wiki/High_De...atible_Digital) and some containing tracks mixed in Dolby ProLogic (example: http://www.ayreon.com/starone/so_albums.html).
is it possible to rip these formats and how ?
i'd like to rip to a lossless - in case of HDCD decoded to 20bit or 24bit - audio file containing all channels (6 for Dolby PL)

As far as I know, nothing can rip the full sudo 20 bits.

any idea about the dolby thing ?

it works !

1) ripping to 16bit wav with dbPoweramp CD Ripper
2) converting to 24bit wav (containing the REAL 20bit HDCD) with HDCD.exe

current version (r185 17.09.2007) can be found here

http://www.srcf.ucam.org/~cjk32/hdcd/

is there a way to do this during ripping (maybe using CLI codec) ?

here are the command line ptions of HDCD.exe

Usage: hdcd [-h] [-o output | -c | -a] [-x] [-i] [-r] [-s] [--] file
Upconvert a 16 bit wav file to 24 bit using HDCD encoding if present

Options:
-h display usage information
-o output output to the specified file
-c output to stdout (Default)
-a suppress output
-x return a non-zero exit code if HDCD
encoding wasn't detected.
-i identify HDCD. Only scans the first 750
frames or until HDCD encoding is
detected. Implies -a -x.
-r treat input as 2ch, 16 bit raw PCM and
and write output as 2ch, 24 bit raw PCM.
-s only write warnings and errors to stderr
-- allow file to start with '-'
file input file. Defaults to stdin.

Rip to wave and use the DSP effect Run External:

After Conversion

"c:\apath\hdcd.exe" [outfile]
