Direct recording in .wma?

Hi all!

I already know how to directly record to mp3 (LAME_ENC.DLL) and .ogg and .wav of course.
I am interested though to be able to record in many more formats directly...
For mp3 and .ogg I just made wrappers to the appropriate encoding DLLs and I use waveIn APIs to record in buffers, then send these buffers to the encoder.

So, does anyone know if there are free DLLs out there which will allow me to record this way in other formats than .wav,.mp3 and .ogg? I am mostly interested in .wma but any other is very welcome.

Thanks!
