Hiya, I encoded a number of AIFF files to AC3 using Compressor for a DVD Studio Pro 4 project and when I replaced the AIF files with AC3 I noticed they were considerably quieter than the AIF files. I read the compressor manual (obviously I was desperate ;-) and it stated that using -31 normalization was the setting to use so that it doesn't alter the file's volume but the resulting files were still as quiet in comparison. I even tried a few tests, pushing that value up and right down and it made no difference. For now I've gone ahead and encoded all my audio assets at -31 but thought someone in here may have a suggestion.
