I'm looking to perform basic sound editing operations (applying low/high pass filters, eq, etc - to get rid of some annoying background buzz) to the audio in an AVI. Anyone familiar with any free or at least cheap tools that can achieve this?
(Windows, POSIX, hell.. VAX if you like)
(PS. Alternatively a software library that can do it would work as well, language doesn't matter. Unless it's VB... anything but VB)
