Conversion of nmf files to wav file format

Even though both the .nmf and .wav are audio files, there doesn't seem exist any way how NiceMedia NMF format could be converted to something else. Considering it features some kind of high compression, or probably data reduction to have very small audio files (something like 10% of MP3), even if you managed to somehow convert it back, the quality would be most likely horrible.
