Subject:AC3 for audio CD? Posted by: JimT Date:4/6/2004 8:08:57 PM I have Vegas 4.0+DVD. For audio production, can I encode surround to an audio CD? I know that both stereo and 5.1 can be layered on audio disks in other programs (don't ask me which ones), can this be done in Vegas or DVD Architect?

DVDA does not use AC3, except in a compatibility layer. DVDA uses uncompressed PCM files, or a lossless codec called MLP to enable 24/96 surround as without it you exceed the available bitrate of 9.6Mb/sec. allowed in DVDA. I do not know if the AC3 encoder that Sony supply will do this either, but it is possible to save an AC3 file as a Dolby Digital WAVE file, at a samplerate of 44.1KHz that will look to the CD writing program like an ordinary WAV file. When you play this into an amp that has Dolby Digital Decoders built into it, as most "home theatre" amps do, you will get a surround output. I do these files out of Nuendo, using the Nuendo DDE.
