Surround Compatible Reference Disks Using SoundCode
SoundCode is a great tool for encoding your latest surround mix so you can make a reference disk for a client or to take home and check it in your home theater.

You can make a DVD reference disk of your latest surround mix in various ways. If you already own a professional DVD authoring application, you can use the AC3 or DTS file output from SoundCode and create a professional-style DVD that conforms to consumer standards. If you use Mac OS X, you probably own the Apple iLife suite. You can use iMovie and iDVD to make a surround-compatible DVD. If you want to really save time and not wait for a DVD authoring application to encode a video, you can put a DTS or Dolby Digital stream on a CD and play it through a home-theater receiver. You won't be able to see anything, of course, but you will be able to hear a full surround mix.

Reference Disk Options
1. Pro DVD Authoring App - Professional DVD authoring applications can use AC3 and DTS files from SoundCode.
2. Mac OS X and iLife v6 - iMovie HD and iDVD can use a DTS or AC3 WAV file from SoundCode.
3. CD Burning App - SoundCode for Dolby Digital and SoundCode for DTS can encode to a 44.1 kHz WAV file for a CD.
Dolby Digital or DTS?
Both Dolby Digital and DTS provide high-quality surround encoding and will work in most situations. Dolby Digital provides more features such as dynamic range processing and metadata control of stereo downmixing. DTS uses more bits and is generally accepted to be higher fidelity. You can find a lot of opinions and information by searching the internet for discussion groups and press reviews.
Surround-Compatible DVD Reference Disk using Mac OS X and iLife™
Apple's fantastic iLife suite contains iMovie HD and iDVD which can be combined with SoundCode to author a surround compatible DVD. The trick is to use the WAV file output feature in SoundCode. Just drag the WAV file into iMovie HD, drag your Quicktime movie into iMovie HD, and select "send to iDVD." iDVD will then author a DVD with the AC3/DTS data stream as PCM 16-bit audio. If you listen to it as analog stereo, you will hear the raw data stream which sounds awful. But if you connect the DVD player's SPDIF/Optical output to a Dolby Digital/DTS compatible home theater receiver, it will automatically detect the Dolby Digital or DTS data stream and decode it to full surround.
How to make a surround-compatible DVD with Mac OS X and iLife.
