Must I use Sound Forge to re-render or volumize the file?

Yes. Or Vegas. Or some other audio editing tool.

If your creating/encoding ac3 in Vegas, check the custom settings... You may be killing your volume during the encode.

There's info in this forum I think if you want to search. Might also search the forums at videohelp -- if I remember correctly there were more than a few threads dealing with what the various settings mean in or to a ac3 file.

Otherwise 1 easy way is to increase the volume for the audio track or bus in Vegas before rendering the ac3. A lot of folks prefer normalize, which simplified pushes your peak levels to the max [though you can control it much better in Sound Forge] -- be aware that this *might* be a little high for your average viewer & how they have their TV set. Might also look at compression/expansion in Sound Forge.

To maintain level, I think there's 3 settings to change.

Under Render to ac3. select Custom ...

Audio Service tab - Dialog Normalization - set to -31db
Preprocessing tab - L Mode profile - set to None, RF Mode profile - set to none

Save these presets and give them a name such as "Maintain Audio Level"
