Hi,
I have old tv show episodes in avi files and the constant white noise is really getting on my nerves. I use VLC to watch them.
Is there a way to make the audio better and get rid of most of that white noise?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Go to your audio card's controls and look a an equalizer. Turn down the high frequencies (~4 KHz and above). For more than that you'll have to spend a bit of time learning some tools. Audacity is free and has a noise reduction filter. But for white noise you can only reduce it 10 or 15 decibels before the remaining audio gets pretty nasty. There are more advanced tools but the cost $ and take a lot of work.

Get the ffmpeg source plugin for Audacity. It will then be able to import audio from almost any file.

Export with whatever codec you want. Then mux the new audio with the original video. VirtualDub can do that: Open the original file, select Video -> Direct Stream Copy. Select Audio -> Audio From Another File, select your new audio file. Then Video -> Save As AVI.

I've never been able to do anything with VirtualDub, it won't even open the original video file. I have CCCP installed, so it should have all the codecs it could possibly want.

32 bit vs 64 bit? 32 bit VirtualDub requires 32 bit codecs. 64 bit VirtualDub requires 64 bit codecs. Neither system can see other's codecs.
Maybe your file isn't really an AVI file? Anyone can rename a file with whatever extension they want. Media players identify the container by the contents, not necessarily the extension. VirtualDub doesn't do that. Check with MediaInfo. -

CCCP doesn't install ffdshow, so i installed both the 32 and 64 bit versions of ffdshow.
I used VirtualDub 64 and it all worked out.
Thanks
