how to rip HDCD audio data without losing its 4bit extra data to a compressed format? using EAC + LAME -> Monkey, FLAC, LAME MP3, or any other???

Many thanks

If I'm not mistaken, the ripper has to be able to understand HDCD to begin with. None that I know of do. It has to be licensed, and to my knowledge, no one's done so.

That being said, if you could rip a HDCD intact, you'd have to go with FLAC, or some other codec that allowed odd bit resolution. MP3 expects 44.1/16 files, last I checked.

hmmm....

I wouldn't worry too much about preserving the HDCD encoding. The mp3s and oggs I've ripped from HDCD disks still sound pretty good, in the same way that a lot of HDCD disks will sound really good even without an HDCD player.

If the plan is to rip them with the intent to burn another copy of the CD, then don't use any sort of compression. A straight copy of the disk will preserve the HDCD formatting.

LAME accepts high bitdepths too (floating point even), but in the case of keeping the HDCD coding intact no lossy compression can do it. Unless of course there is a software decoder for HDCD which could output in 24-bit standard PCM including the "20-bit" resolution of HDCD (and thus allow lossy compression take advantage of it).

I just had an idea about this... what about CloneCD, or a similar product? One that makes a 1:1 copy of the disc; and doesn't care what's on it. That should, in theory, preserve the HDCD encoding.

steph: yes, it does. Doesn't help with storing it in a playable format in your computer / portable player, though.

Copying HDCD discs preserves the HDCD.

But ripping and encoding into lossless does not seem to. I don't have an HDCD DAC anymore, but my Grace m902 shows 44.1 for tracks that I know were HDCD.

Aye, but someone had mentioned just wanting to make a copy.
