AC3 sound levels used for DVD
by Gern Blanstein on Jan 8, 2008 at 6:34:21 am

I am editing six, uncompressed (PCM) mono streams and the relative levels are presently appropriate for a music CD, but they are too high for DVD.

I know that AC3 streams demuxed from a commercial DVD are typically attenuated, but I am clueless about the standards and specifications.

Can someone offer any guidance on preparing audio data *before* rendering the 5.1 surround track?

Thank you in advance :)

You might want to take a look at this web page:

http://www.dolby.com/resources/tech_library/index.cfm

in the drop down list look under Cinema or Encoding/Decoding,
there are a few PDF you can look at, or you can go to this site:

( a little less to read but well done )
