This file uses ADPCM encoding (a form of compression based on non linear
encoding of each sample), which is most likely not supported by
scipy.io.wavfile. Your two options are to convert this to a "normal" wav
file with linear encoding, or to use audiolab which supports those files
(because libsndile does).
