Chris (coowouters) gave me this link a couple of weeks ago, it's does a lot of different conversions ............. [

Open Wavosaur,
In "tools" choose "Batch processor", then in pop-up choose Source and destination directories, then in "function" choose ....(whatever you need to convert to)...............hit start and wait until the program has finished converting. Open the destination folder and there are your new files......
