I would like to have a [url removed, login to view] function to normalize an audio file.
If you pass in the local path of the source file and a destination local path
the file will be copied from the source to the destination at a higher volume (will be normalized).
You can use the Naudio sample asp or toolkit to accomplish the task. ([url removed, login to view])

I've currently working on (successfully finishing, actually) another NAudio-based project. I can build the normalizing tool/function you need as per your requirements, however, I would build it in C#/.NET.
