Have any of you played around with the following technique?

A DD or DTS 5.1 soundtrack is cleverly converted to a stereo WAV file that is then burned to a plain vanilla (red book) audio CD-R. The resulting disk is played on DVD player connected digitally to a DD or DTS decoding sound system. The DVD player thinks it is playing a stereo audio recording of static and dutifully outputs PCM to the sound system that detects it as either DD or DTS and decodes it as a multi-channel soundtrack.

The technique and how the content is created is described more fully at

Does anyone know of other sources?

Very curious. I hadn't ever heard of this...

It does work, in fact one can also get Powerpoint to play out DTS or DD tracks.

I hate to ask, but as one who's sat through way too many PP presentations ... why on earth would you want to do this?

Ditto, why would you want to convert DD to stereo then back to DD?

touche'!

...you're not converting anything.... the recorded cd (and / or wav file) is just the raw DD or DTS data

Then when you output that bitstream your preamp treats it as DD or DTS (because that's what it is)

This is the only way that I'm aware of to contain 5.1 sound on a CD. Its pretty nice... you can download some wav files from the links in the original post, burn them to a 9 cent CD-R and play them on your DD or DTS system (but not a plain CD player). Its a blast... give it a try.

The link describing how its done is dead, tracked down and eliminated by the recording industry police no doubt.

I would have to ask too.....why would you want to do this?

This is the only solution I've encountered for the following problem...

How do I distribute some 5.1 material over the internet in a way that most users can then play it on their 5.1 sound systems. This technique requires only that the user have a computer that can burn music CDs and a 5.1 capable sound system.

soundhound... you could use this to distribute short samples of your work or to provide an illustration of some contentious issue to other Outlaws.

I suppose now, given the prevalence of DVD+/-R, this technique could be replaced by a more direct solution, but that would narrow the potential audience.

Try the content links in the original post, download some tracks, burn them to a CD-R and give it a spin. If nothing else, it is some free 5.1 content to listen to.

Dahhh...
