Use of AMR-Wide Band Codec

I am working with 3GPP AMR WB codec and I am able to successfully compile
the encoder and decoder and also run it as mentioned in the document using
their voice samples (tst.inp and dtx.inp). I want to implement the codec to
encode and decode any general sound (.wav file). How can I do that ? I have
tried to convert the .wav filr to .inp which is not happening and then I
also tried to use wave file as input to encoder but am not able to
implement it.  Can I get some help in this regard.
