Dolby Digital ENCODING sound cards

I was just wondering if anyone here know any sound cards that do this. I love my Sound Storm for is ability to encode in Dolby Digital 5.1. I have my comp hooked up to a home theater system using optical out and I really dont want to loose that when im forced to change motherboards.
So any ideas?
 
Not DD, (AFAIK) but Creative has an upsampling that works similar PL II in that it can take a 2 channel input and make is sound like a surround source. (somewhat) You may be able to use the optical or S/PDIF connector as well.
 
If he's got a receiver, then can probably do some matrixing too, without the need to buy more hardware. Matrixing is just not the same as a DD with dedicated channels. Sorry.

Look at this thread to see a new card that supposedly will do real-time hardware DD encoding.

Nope, you can't. This also would require DICE to do, which Creative doesn't have a license for.
 
How does Creative not have a license for DICE?
Do they not own Sensaura?
 
I have my original SB Live plugged into my home theatre system on the HTPC downstairs. All I needed was AC3filter (google it) and all the XVIDs I play send a Dolby Digital signal to the SPDIF out. I can verify this because my receiver lights up the "Dolby Digital" light as soon as I play something with AC3 encoding. For stereo content through the SPDIF, it only lights up the "Dolby Prologic II". It seems as though I can encode it...

Careful.

I tried to say this in a previous thread, and I got torn a new one.

Really? Didn't know that, I figured that you had to have a separate license for each piece of hardware...at least, that's how I'd structure my licensing :D

Really? I thought it was [fairly] common knowledge that you can use AC3Filter to do that...just not for games. However, I don't think that anybody claimed that it would work for games in the first place.
 
here we go again... :p

Creative does not have the hardware, or license, for the Dolby Interactive Content Encoder (DICE). Sensaura doesn't own any rights to DICE, Dolby Labs does.

AC3Filter is a DirectShow filter that will decode existing Dolby digital streams or pass them through SPDIF for external decoding. It will not matrix non-AC3 content and encode it into a Dolby Digital stream that your receiver can understand in real time.

XVID is a container format that is capable of delivering a pre-recorded Dolby-Digital soundtrack. Whoever ripped your XVIDs would have done it from a source that had a DD track available (like a DVD, laserdisc, or some HDTV broadcasts), and attached the Dolby Digital stream without transcoding it to mp3 or ogg, or whatever.

While you can matrix 2.0 channel content up to 5.1 with AC3Filter and MatrixMixer, you can't pass the 5.1 information through SPDIF to your receiver. Choosing "SPDIF" in the AC3Filter speaker configuration makes it so that Exisiting Dolby Digital streams are passed through without processing, and any other audio streams are sent in 2ch PCM mode. AC3Filter is useful if you have analog 5.1ch speakers, or if you're sending pre-encoded Dolby Digital streams to your receiver from WMP, ZoomPlayer, BSPlayer, etc.

Sorry. I didn't mean most it to sound as harsh as it did, but the thread got locked before I had a chance to comment on any of it. I've been messing with this stuff for quite a while, trying to get my HTPC perfected.

Actually the latest version of AC3Filter can take 2ch PCM Matrix convert it to 5.1 channel DD stream and SEND it through to SPDIF in realtime. I do this currently on my HTPC with mpeg2 streams recorded via sage and connect my HTPC to my Denon reciever via spdif

I need to try this. Thanks for the post; time to toy with the HTPC again.
 
I tried posting about this in another thread, but didn't get much response... Do any of you know any "best practices" for AC3filter settings when running to an analog 5.1 system aside from the standard "whatever sounds best"?

Thanks
