Just a few questions on Eyes of Horus's Guide.

Please refer to Number 16

When I switch to the X signal (the X file we've been working on). Resample it to a 16 bit mono file, do I keep it with a 50% mix on each Channel? Do I enable dithering?

Please refer to Number 18

When I switch to the Y signal, do I enable dithering?

Your help would be appreciated.



1. Rip a stereo track from a CD

2. Using CoolEdit and Aurora, do this.

3. Start CoolEdit.

4. Load the UHJ-W filter file ,a 44.1 Khz file . Copy it to the windows clipboard. Press CTRL+6 for Windows Clipboard and the CTRL+C to copy to that clipboard.

5. Load the stereo signal (the ripped stereo track you want to convert).

6. Launch the "Convolve with Clipboard" Aurora module, and set the following settings:

8. Channels to convolve: Audio data: Both. Imp. Res: Both. No Crosstalk cancel mode. No remove DC component. No autorange result. No timeReverse Imp. resp. Gain =0.

9. Convolution begins. When it ends, you'll have a stereo file. We need it in mono.

10. Convert Sample type, from Stereo to Mono, with a 50% mix on each channel and 32 bit resolution.

11. Close and restart Cooledit. This is necessary to be sure that the clipboard is empty again ! Make sure you set the Windows clipboard (CTRL+6)

12. Repeat the procedure, but load the UHJ-X and UHJ-Y files, so you end up with three mono files (which will be your w, x, and y signals).

13. Now remember, the "Z" component means "height". So we really don't need to decode it.

14. Close and restart Cooledit


15. Now we have to pack the W signal along with the X signal.
Re-transform W in a stereo wave file, with 16 bits depth, using the Convert Sample Type module in Cooledit. Be sure 100% of the signal goes to the left mix, 0% to the right, and that resolution is 16 bits. Enable dithering.

16. Now switch to the X signal (the X file we've been working on). Resample it to a 16 bit mono file and Copy it to a Cooledit Clipboard. Go back to the W signal, select the entire right channel and paste the X signal file into the right track of the W stereo signal. You'll end up with a stereo file with the W signal on the left channel and the X signal on the right channel. Save it !

17. Close and restart Cooledit

18. Switch to the Y signal. Convert it to stereo, 44.1/16. The Y signal will be 100% on the left channel. Since we don't have a height (Z) signals, the right channel signal should be left empty. Save it !

You're wasting your time pal, there is no way to get real 5.1 sound from stereo. Keep your stereo track as is.
Even professional studios can't remaster stereo to real 5.1, this is just impossible.
If it was that "simple" as eye of horus or anybody else describes, we would see almost all DVDs with 5.1 tracks, but that's not the case.

Since I have the software, I would like to try it anyway. If anybody can help I'd appreciate it.

That's the spirit...

Number 16 - It's converting to a mono file. There is no left or right so don't worry about the setting. Dithering is Yes.

Number 18 - Yes to dithering.

This is certainly not true 5.1 but then nobody said it was. It does, however, sound better than stereo IMHO.

Yes it does sound better than stereo ! That's why I wrote it in the first place.

But I am getting a bit tired of that "this is not true 5.1"....

This is true surround ! OKAY ?

Hi EoH, glad to see u back.

Please do not think that I am trying to argue with your method or results. In fact, I try to promote your method whenever possible. If someone follows the guide and does not like the outcome, they don't have to do it again. I do like the results and will continue to make conversions.

Regards
