How to modify sound in a WMV?

[FredThompson]

I'd like to modify the sound in the video tutorials from http://www.cswebs.org.uk/video.htm so it is louder.

How would this be done to WMV files so the video portion is unmodified?

Turn up your volume control. :p

But seriously, if I needed to do this I would:

- Decompress the audio into an uncompressed WAV with GraphEdit
- Amplify the sound with Audition (or the audio editor of your choice)
- Compress to WMA (perhaps lossless?) with Windows Media Encoder 9 (http://www.microsoft.com/windows/windowsmedia/9series/encoder/default.aspx)
- Mux the new WMA and the original WMV (just the video) with Windows Media Stream Editor

Windows Media Stream Editor comes with WME9. Hope that helps.
