What would be the better way to volumn up the ac3 sound?

[cpthk]

I go to ac3filter, and turned up the gain and/or the enable DRC. It did turn the volume up. But the sound quality isn't as good as original. Even the same volume gives worse quality than before.

What would be the best way to turn up the volume?

Thanks.

1- :readrule: don't ask what's best

2- what you describe is most probably due to low-quality soundboard/card and/or low-quality speakers. Could you post your settings?
There´s also to know that when you turn the gain up to much, you get clipping which is also responsible for low-quality output.

This is the video file's problem or my computer's low quality sound car?

Well, if you turn volume up too far it'll always clip by nature, because it can only go so far up before peaks hit maximum. If you get loud bursts of static on loud parts, that's exactly what's happening, and you need to turn the gain back down.

If you get really painful distortion when you turn the speakers up all the way, especially around the mid-high range, you're just driving them harder than they can go.

Sound cards usually only cause low-level hiss, not so much distortion, unless you have a really old one.

You can either apply heavier DRC, which doesn't cause static and generally sounds better (but loud sounds aren't as loud relatively), normalize it (which results in levels going up and down all the time, unless you're re-encoding, then it's almost a must), or you can buy a better amp/speakers that'll go louder without distortion.
