Automating audio file conversion

Hi all!

In Nero Burning ROM, under the Extras menu, there is a wizard that allows the conversion of audio files from one format to another. However there is no easy way to pass to it an entire directory of such files or to preserve the directory structure of these files in the output file list. Furthermore it seems that at least with some file formats (e.g. M4A -> WMA) tag information gets lost during the conversion.

I am looking to write a script or simple program (Python, C# maybe?) to automate this process. Specifically I want it to:
1) Recursively scan a directory for files of a supported type (or even types).
2) Read from them all meta information.
3) Use Nero to convert them to a specified format.
4) Preserve the information read in step 2 and based on it either create a new directory structure or recreate the original structure.

I have downloaded the SDK and read a bit through its documentation (also checked the nerocmd.exe help) but all I could find was either hardware related or had to do with CD/DVD burning.

Can anybody point me to any examples or tutorials about manipulating audio files with Nero SDK?

Many thanks in advance!
