I've just bought a DVD which is recorded quite softly. It was for my mother who is quite deaf and wears two hearing aids and has the volume up a fair bit. This DVD just won't go loud enough. Considering it's got a fair bit of music in it, subtitles are not the whole answer. I've been looking around for how to raise the volume and can only come up with - demux video/audio, convert AC3 audio to WAV, use Audacity to raise volume convert WAV to AC3 remux video/audio streams re-author VOB/IFO files together It's a bit of a journey with eleven VOB files to process. Does anybody know of an editing application that will take the whole movie and batch these operations into a single pass?
