I've demuxed an AC3 file (DD 5.1 stream) from a DVD movie. Trouble is, i find the overall volume to be a little low. Is there a way to increase volume without reencoding, like mp3gain style?

Would like to avoid re-encoding as this will result in quality loss. Thanks.

I don't know much about the subject but I think you're looking for someway of ReplayGaining the file. This topic might be some help: http://www.hydrogenaudio.org/forums/index....showtopic=11063

ac3 is always low, enable DRC on your decoder (if its ac3filter turn on drc and crank up the preamp for it, maybe even move up the main gain)

I'm not sure if this is the right thing to do here, but technically it is possible to do a lossless gain change like it can be done for AAC files -- but only in steps of 6 dB. (I guess no program has been written to do this yet. So this reply is not of much use for you unfortunately.)

I just wanted to mention it.
