Download
As usual, you can get a full installation program for the Wma encoder. Of course, that’s 100% free.
Update
You’d better check you don’t already have a WMA encoder installed before getting mine. Starting with Winamp 5.091, Nullsoft sometimes ships its own-written WMA encoder with the full edition, featuring more bitrate profiles.Download
Here’s the latest public version of the Wma encoder:
Nothing special to state here, except that it’s bundled with the Wma standard 9 codec. That means that if you don’t have the Wma Std v9 codec installed on your system, the setup program will download it from the Microsoft website and install it for you. Please notice that we are speaking of the codec here, and not about the Microsoft’s player or whatever else
