Internal Converter from specific Audio-Formats to .wav or .mp3.

Background is: I got tons of Audio-Samples, which i can´t use within Cubase, because they are not supported. so maybe it could be nice to got a File-Converter inside or outside of Cubase to use this Samples, too.

P.S.: Doesn´t mind of any Programs which can convert.

Thanks for listen.
