For audiolab:
  - more features
  - is likely to be faster, since it uses libsndfile which is coded in C
  - handles more file formats (libsndfile is by far the best library for 
audio file IO and handles a lot of software-specific details).

For scipy.io.wavfile:
  - pure python and no need for 3rd party library

License-wise, audiolab is LGPL (because libsndfile is) whereas 
scipy.io.wavfile is BSD as the rest of scipy.

cheers,

David
