HDCD home recording

[sax512]

Hello. I'm new of this forum and I'm from Italy, so I suddenly apologize for any further misunderstanding. I'm a cassical guitar player and I would like to make my own home cd. I have an m-audio firewire 410, two m-audio nova mics, a pair of studio monitor hs80m by yamaha, and I'm going to get a mini mac for recording. Until now, nothing new or difficult...
The fact is that I saw this HDCD enconing technique and I was wandering if I could make my cd with this technology.

Are there any programs that will get as input high resolution 192 khz 24 bit tracks and make an hdcd?

Then again, I know that wmp is the only software that can decode hdcd and I never had a mac but I'm quite sure there is a wmp for that too. I noticed that wmp can decode hdcd only from cd. If you try to open flac or other supported lossless files the logo doesn't appear anymore, so I guess it doesn't work.
How can I do without mastering all my flacs into cds?

Thank you very much for your answers and best wishes for this wonderful forum. I'm sure I'll hang around here often.

I couldn't find anything helping from the search above. Please someone answer my questions if he can....

Hmmm i dont understand Your question - did HDCD mean quality better than regular CD is capable (ie better than 16 bit dynamic) or HDCD proprietary and patented encoding scheme which require at the decoding stage also special HDCD decoder (which is available only on some particular equipment)?

If You are interested at only higher quality then probably special postprocessing will be fine for You - at end of project some noise shaping should be used by You (http://en.wikipedia.org/wiki/Noise_shaping) for example a POW-R (http://en.wikipedia.org/wiki/POW-R).

If You looking for particular HDCD patented solutions You must buy license for HDCD from owner of HDCD.

Hi, thanks for answering. By HDCD I mean tha actual HDCD patent encoding. I want to make my own cd but just for me and some other people, so I wouldn't want to buy licence for it. All I know is that HDCD is used with anolog records to encode them in digital. What I'm asking is if it is possible to encode a track recorded in high definition, for example 24 bit, 192khz, made with one recording program such as Nuendo, and obtain an HDCD encoded CD. In a few words I'm looking for a pirate program that can encode HDCD without license, if that is possible to do from a digital high definition master. That would be the main goal.

Ok, i see... at first - there is no possible to have sampling frequency on CD higher than 44100 samples per second (so any other sampling frequency must be resampled to the 44100 samples per second), other problem is that probably not exist alternative encoder (alternative to the owner of HDCD technology - present time Microsoft, earlier Pacific Microsonic).

No dubt about it, the 192 khz I meant were for the original track, the one that should be encoded in HDCD.

That's what I am wandering. I would think the same as you, but I'd like to have a precise indication from someone who knows it for sure...

I think there is no way for your requestings. You only can encode to DVD-Audio or Flac your High Res recordings. Maybe to dsd (Sacd) too, i'm not shure.

A HDCD media is limited to 44,1k sample frequency by design. It's the same as regular CDs. However the bit depth can be as much as 20 bits I guess, thus enhancing the sound when played on hdcd compatible hardware. And ONLY when hardware is compatible.
Playing a HDCD on regular CD player gives you nothing but compressed sound with high volume still and no original dynamics intended by the engineer, even if we're able to recognize the song played :)

So you can encode your highres files into 44,1 to fit a CD by doing some downsampling. I would use r8brain or Wavelab's UV22HR to do so.

For Hdcd encoding, I don't know think there are any diy encoders. This is a patended design, even if hdcd decoding has been "cracked" (eac3to does it perfectly with the -decodeHdcd switch).

I hope I could answer your questions the more precisely possible :)

Best regards,

HDCD is very nice if you decode it as such, but the CDDA track is terrible....it's mostly 14bit :eek:

go w/ DVD IMHO, you can do 24/192 LPCM I think...or at least encode it to DTS 96/24?

[Ghitulescu]

So no encoder yet?
