So I got a bunch of raw dialogues, from my voice actress, that I'll like to polish a bit.

Right now all I did was noise reduction, and it sounds okay, I guess. But are there any other filters and effects that'll be helpful as well?

The most important part of audio is that you have a good recording device and environment. So if either (Or both) one is bad, there's not much you can do. You can do noise remove. You can do a high or low pass filter (A VERY mild one, set the cutoff very low for low pass (Start at 100-200 and tweak it until sounds is good, start at maybe 1000 or 1500 for high?)) if it's too tinny or bass heavy. You can normalize for audio levels, but that's about it. If it's bad audio quality to begin with you can only round off the sharp edges, you can't work wonders and make it sound awesome.

Actually, the recording is pretty good of itself.

Sometimes the volume varies between each sound clip, and that's what's tough, bringing them all closer to Skyrim's volume level.

Have to do them all by hand I guess. Potentially 276 sound bytes to go through...

But, hey, thanks for the tips! I'll try them out and see if they make an improvement or not.

Balancing them all at once is very easy. Open Audacity, then hit Control+Shift+I, select all of the files at once and hit import/open. Let them all load. Then, without selecting a single one, click effect>normalize and normalize to 0db, or possibly -2db if it's a heavier voice. (Some of my big guys are a bit quieter so it's a softer sound with their heavy voice) Audacity will now normalize the volume of ALL loaded files.

It sometimes crashes for me, so if it does this, simply abort the program and force it to quit. Then open it again, recover your project, ignore the warning, and do export multiple. Export them all and you have nice balanced files.

Remember to make sure that they are 44100hz, 16-bit mono channel Wave files so that the CK and XWM/FUZ software can handle them properly.
