The site has an English version and it is so simple! You download the ZIP-file, unpack the WAV-file and burn it on a CD.
When you put it in your DVD player with DTS it will be recognized as 5.1 DTS multichannel recording.

Norrlanda marsh

Norrlanda marsh on the Island of Gotland surrounded by forest and field. An early morning in May You could hear the Snipe, the Yellowhammer, the Corncrake, the Chaffinch, the Redshank, the Willow warbler, the Linnet and distant the early morning bell of the medieval shurch, Norrlanda.
The recording are made in four channels. the microphones are placed in a square with the side of 25 cm.
Recording date, 18 of May 2005 at 7 o’clock.
Produced by: Björn Carlsson

It is lovely!

There are other files too.

This is simply a DTS Disc, an idea that never really caught on in the music industry. I have a few of these. The sound quality is OK but not "lossless" by any means. Mostly they are victims of poor quality mastering, the technology itself is not to blame. The main difference between this and the standard DTS surround track on a DVD is that this is 44KHz instead of 48KHz.

When listening to the mentioned recording "Norlanda march" you will forget the technical issues and you will want to make a ride to Sweden I suppose. :thmbsup:
In the Sound Archive (http://www.sr.se/cgi-bin/mall/artikel.asp?ProgramID=2446&Artikel=740607)
there are many more recordings, many more jewels!

On Ambisonic.net there are some informations about decoding different multichannel recordings into the 5.1 format (G-format),
especially recommended Getting Ambisonic Around (http://www.ambisonic.net/pdf/ambisonics_around.pdf) :

There are some Multichannel-wav's for simple burning and listening. :thmbsup:

In Ambisonic you can use a microphon or you compile the electronic sound with a mixer. The examples in the preceding posting show the results.
This is my prototype of an Ambisonic microphon (four capsules).

Does anybody know a software for recording four distuingished channels preferably for Linux or Windows ?
(It is not meant to mix several channels to stereo.)

If you have the card then Adobe Audition should do the job. John

Is this easy to do? Do I load the DVD RW up with disc and record or save information to it and then play it back on the Pioneer DVD player hopefully with dts six-track. I haven’t burned a DVD or CD before, well not a CD that is in several years.

Ashley,

it is easy, but unfortunately I can't help with your burning program, I use cdrecord.
You have to care that it is a music and not a data file,
And you have to burn these DTS-WAV examples on a CD. For DVD it had to be coded a bit differently.
You put the CD in your DVD player which must be suitable for DTS and all is fine (no menue).
In a normal CD player you will only hear hiss.

For me these examples have been nice experiences.
Btw. Ambisonic is a British invention.

If you are interested in your own mike recordings in an acoustical adequate environment then the following might be of interest:

On Hauptmikrofon.de (http://hauptmikrofon.de/dm_download.htm) there is - following the menu "5.1 Surround / Downmix" - a downloadable comparison of different miking techniques in surround and stereo downmixes. Involved are

IRT-Cross big or small
Decca-Tree
OCT 1 and OCT2
INA3

The text is in English, a Powerpoint-Demo gives some first explanations.
The files must be burned on a CD as audio-files, they must be played back with a DTS capable player.

At first "sight" there are only very small differences. (The first files contain hiss, don't be confused ;) )
BTW. a comparison of different condenser and ribbon mikes is mentioned in this forum (http://audioheritage.org/vbulletin/showpost.php?p=226233&postcount=23) .
