Hi Chris,
Will this help you figure out those transient bits? I downloaded your files and made a test CD. One Mark Knopfler HDCD song and your 4 test files in this order. 1_Cannibals_08.wav 2_hf_sweep_nf.wav 3_hf_sweep_tf.wav 4_impulse_train_nf.wav 5_impulse_train_tf.wav I played the CD with RCA SPDIF to a late-90's vintage Parasound DAC1600. The HDCD light came on for all the tracks. The Parasound has the original PMD-100 chip configured to decode HDCD, oversample 8X and feed the Burr-Brown DACs. I connected the analog out through a passive volume control. ADCOM SLC-505. Then to the line in input on a PC with NVidia sound chipset. Asus A7N8X-E. Then I recorded a 24-96 wave file of the line in. If you would like the file , let me know the best way to get it to you. It's too big for email. 26.6 mb compressed with flac. I cut off most of the Knopfler song and left the ending in. |

Hi guys. I'n a new entry on this forum and I posted a thraed where I was looking for information about handling hdcd. Here is the link:
http://forum.doom9.org/showthread.php?t=133756 I resume my questions here: Can I convert high resolution traks into HDCD? Can I read HDCD without ripping my flacs, ape or whatever into cds? Lookink through this thread I noticed that you were speaking about how wmp decodes hdcd. My english isn't so good so I didn't get all the stuff about filters. I think I understood that wmp doesn't decode hdcd in a full and proper way. Am I wrong? Anyway, I also downloaded hadc.exe but wasn't able to use it. Actually I'm not quite sure what it's for. Is it a player that can decode hdcd? How can I play a track with it? An last, can I play hdcd with wmp in OsX? Thanks for your further answers. |

I don't know there is any HDCD encoding software around for your raw tracks. For your APE and FLAC, you can decode them into 16-bit WAV and then further decode it into 20-bit WAV (though in 24-bit format) using cjk32's program.

Thank you. Actually Ihavent been able to make hdcd.exe to work. I downloaded it but when I open it there's just a black screen. I'm not so skilled with programs so if someone can explain me precisely how to use it that would be great..

sax,
We can't just tell you how to use the command line and expect you to be an expert. You have to learn and experiment. First of, open a new command line by running the cmd command in your Run Dialogue. Then navigate to were the executable that you downloaded is using the command "cd ..." Like Quote:
hdcd.exe or something like that. It should be pretty self explanatory from there. Last edited by Adub; 31st January 2008 at 22:46. |

yes. my config:
put the source file in the same folder and write (in command line, Merlin7777 following) this: hdcd.exe -o outputfile.wav sourcefile.wav - ALL NAMES WITHOUT SPACES BETWEEN WORDS - - SOURCE AND OUTPUT FILE NAMES MUST BE DIFFERENT - quite simple. example: D:\Docs\MY Music\HDCD\hdcd.exe -o whereismybrainRESTORED.wav whereismybrain.wav Ah! If the app shows "HDCD not detected" alert, means that you source file IS NOT HDCD CODED. I'LL RECOMMEND an "Microsuck" app called PowerToys, which give you a "direct from any folder you chose" with your right click button Command Line function. good luck.

Hi there. I had been able to decode with this program. It's very simple once you do it for the first time. I wonder how it can decode the 24 bits out of a 16 bit wav if hdcd is property of microsoft. Maybe Chris can answer this question. I'm wondering also if when it comes to listening from an HDCD with WMP or listening to the same cd encoded as a 24 bit wav there is any difference. That brings me back to the question I made about the post when it's said that WMP does something with filters which I couldn't understand complitely. The post is this:

I've not abandoned the app, just been rather busy lately, and as I've not logged in here, I've not picked up any of the private messages. Hopefully, by the middle of next week I'll have some more free time, and will go through and address all the point accumulated in the thread. For future reference, you're probably best contacting me via email, cjk32@cam.ac.uk. Regards, Chris |

Can you improve the program by let it accept parameters so people can make front-end for it? Command line is clean and simple, but some of the user may prefer drag and drop (like the famous LAMEdrop), it'll be much easier for them. Once again, thanks for sharing the program with us.
