[Clixo]

try to upgrade to a newer version.
here's the readme :BeSure v1.1 by DVD2SVCD.
------------------------
this program allows a direct conversion from VOB/AC3 to CD.

Information
-----------
BeSure can create two types of wavs. both can be burned as a CD Audio (CDDA) :
- CDDA Mode : 44.1Khz/16bit/Stereo.
- DTS-CD Mode : A 5.1DTS surround track, preserving all surround infromation from the original AC3.

Downloads
---------
BeSure is a front-end that use the following engines :
1. BeSweet v1.0 (or higher). can be found at : http://DSPguru.doom9.org
2. SurCode CD Pro DTS v1.0.9. can be purchased at : http://www.minnetonkaaudio.com

Pay Attention that 'SurCode CD Pro DTS' is only needed for DTS-CD creation.

i have the latest version available i will make a few more test and will report back.

[DSPguru]

and is your reciever on DTS mode ?

[Clixo]

@ the great dspguru

what do you mean ? i have digital exits of sound and what i get is only noise.
tried it again and the mono tracks are ok but the result is noise. one question : can i her the mixed sound with an normal sound card ? sb 128 pci ?

i will dl some test files from the developer of the encoder to check if i have an hardware problem. thanks for yor attencion

[Clixo]

i tried the samples with the same results opf my ones. i will solve the hardware probs and reply back.

[DSPguru]

clixomano, few tips :
- you should have a digital connection between your player (dvd/cd/pc) and your reciever. (optical or coaxial cable).
- your reciever should be able to decode DTS. (most of the reciever decodes Dolby-Digital, but not all of them decode DTS).
- your reciever should be set to DTS decoding and the input should be set to : DIGITAL.

hope this helps,
Dg.

[Clixo]

it works perfect :D thanks DSPguru for your suport.

[DSPguru]

Great :D
BeSure is my favorite tool these days :) !

[MaTTeR]

Perhaps we will have to work on a DTS FAQ soon:D

[puppet_m]

All I got is a "list index out of bound (-1)" error when pressing the "go" button.
Anyone else have this problem too?

For information, I tested it on 2 machines, one with W2K, and another with WXP.
And the author didn't mentionned his email...

[Clixo]

by default stream 80 is choosen , change to the correct audio stream usualy is 81 or use ifo edit to check it

[puppet_m]

In fact the files I want to decode are demux AC3 files, not VOB files.
Maybe this bug only happens when selecting AC3 files.

[frankm]

I have also the problem with "index out of bound". The error does not occurs, when you select an entry in the listbox before press OK.
Additional, I have problems when I use VOB-Files and using the Sort-Button. Then I get an exception after sort and then pressing OK. :(

Even so this program is my favorite, converting Music-DVDs to DTS-CDs.
Before using BeSure, I converting by hand: (Smartripper, azid, sscr, channelx, Surcode) Timeconsumption 3h and a lot of work. Now with BeSure: Timeconsumption 1h and a few mouse clicks.:):):)

Big thanks to DVD2SVCD and DSPGURU!!!

[puppet_m]

It seems to be working.
Thank you.

I hope the author is aware of that bug and that it will be removed in a future version.

I created a Dolby-Digital CD using BeSure. If I play it in my DVD-player (connected to DolbyDigital/DTS compliant receiver) I hear just noise.

This is what I did:
- I made a backup of a DVD's Audio Channel, using DVD2SVCD/DVD2AVI.
- - The extracted audio (ac3) plays ok on my 5.1 audio card.
- I split the ac3 into several tracks using BeSplit.
- - Each track (ac3) plays ok on my 5.1 audio card.
- I use BeSure to create DD-WAV (one WAV per AC3-track).
- - The DD-WAV tracks sound like noise on my 5.1 card.
- - This seems where things start to go wrong:devil:! However,
- - maybe my PC-system can't play DD-WAV format?
- I burn the DD-WAV tracks to CD with Nero (as audio CD).
- - The CD-tracks sound like noise on my DVD-player. Both my
- - stand-alone and my DVD-player in my PC.

What am I doing wrong?:confused:

this way, the reciever will recognize the data as DD and decode it, otherwise, it will try to play the streaming bits as music and it will sound like noise.

[jansb000]

On my stand-alone I have a digital connection to the receiver. (The player itsself is also DD/DTS enabled and has 6 analog outputs - that I do not use since I use the SPDIF connection to the receiver).

As I stated in my post - The same effect occurs when I play the generated WAV file on my PC-harddisk with 5.1 DD/DTS decoder. The same occurs when I play the CD from my PC-DVD-player.

My stand-alone DVD player is a Sony DVP S725D.

Added later: I create DD-CD not DTS-CD. According to docs BeSure should be all I need for this.

[jansb000]

Just for your information:

- - - Warning: Sad story follows - - -
I tried to play a CD (filled with DD-WAV files from BeSure) with WinDVD (4.0 DXVA). Same problem that I described earlier - it plays noise only.

Interresting fact: WinDVD gave me this information shown below.
First it says that SPDIF = OFF and the number of speakers = 2 which is definitly not true. In my system (and in WinDVD settings) SPDIF is on.
It also says that CD sampling frequency = 48khz (should be 44.1 ???) and the number of channels is just 2 (should be 5.1 ???).

The thing is that I have noticed earlier that AC3-2.0 tracks are not played correctly by WinDVD. Some DVD that I have with AC3-2.0 plays also only with noise similar to what I hear from the BeSure tracks.
(but this DVD plays ok on my stand-alone DVD player - the BeSure genertaed CD doesn't)

try plaback that wave in winamp/wmp and check its properties.
if sampling frequency is different than 44.1khz - that's the source to your problem.

Hi,

I'm trying to rip a DVD to a DD-CD.
Extracted ac3 files correct.
When I want to (re)encode the AC3 file to a DD-WAV I get noise.
Some facts (I've tried it with AC3Machine and BeSure as frontends):
BeSweet v1.4
BeSure v1.2
Ac3Machine v0.41 (09.28.02)

The generated file is (according to WinAmp v2.80):
PCM, 44100 Hz, 2 Channels, 16 bits per sample.

My BeSweet log file:
BeSweet v1.4 by DSPguru.

how did you playback ?

[Chris_147]

I tried it with WinAmp 2.80 and Windows Media Player 8.0.
Also burned it to a cd and played it on my DVD player.
That one is connected digitally (optical) to my receiver.
Playing normal DVD's is no problem with it, so I guess I shouldn't change any settings for a DD-CD...

Any suggestions?

Chris

Hi,

didn't receive an answer to my last message, so posting here again.
Maybe you guys just forgot...

I still have the same problems :(, so any help would be really appreciated!

[Striider]

Howdy folks...I really want to try making DD encoded audio CD's. I have tried to use the instructions from this page: http://www.doom9.org/index.html?/ac3machine.htm

Ok, I tried this for hours last night, and apparently AC3Machine is supposed to output a DD encoded WAV file...it never did..only a very large ac3 (I even tried renaming the extention manually in the program). I started with a WAV of a new Peter Gabriel song. So I tried playing it in Power Dvd 4, and it wouldn't play. I changed the file extention manually to a .wav and it played, but all it is was a chattering noise. I tried using the BeSweet GUI with the same results...a great sounding ac3 in compressed format that does play thru power DVD, but when I try to make a wav, it is output as a .wav file, but is nothing but chattering. The track is even the right length, and it plays in my DVD player downstairs, but makes no sound there.

I set AC3Machine to output a log file, which it never writes either, so I can't include a log file for troubleshooting.

I have an Athlon 1.3 T Bird Windows XP, with a SB Live audio card and Power DVD 4 (XP)

I read the forum for hours looking for answers, no clues. Any suggestions?

[jsoto]

Striider,

AC3Machine (really besweet) outputs a log file, but AC3Machine 0.41 has a minnor bug. It does not put the logfile name between quotes, so, if you are using some spaces in your logfile path, you will find it with a shorter path... I find it in "C:\Archivos" , because my path is C:\Archivos de programa\BeSweet.....

Hope it helps
