AUDIO: AC3 volume seems too low

Reported by: eriktorbjorn Owned by: eriktorbjorn

Game: Zork Grand Inquisitor

Description

The sound volume in the hi-res Zork: Grand Inquisitor movies seems much lower than the rest of the game, or their low-res counterparts. Does it have to be artificially boosted?

The AC3 decoder does tell the library that it wants samples scaled by 32767 (from their original -1 to 1), which should be right. But maybe the level is simply too low in the files? Perhaps we should add some sort of "gain" parameter to the decoder so that each engine that uses it can make its own adjustments?

I'm looking into this. Boosting the volume is easy, but it seems I can't use the same amplification factor for all of them. I don't know - and honestly don't particularly care - if this has to do with the movies or with the decoder. I'll submit a pull request when I'm done.
