Migrate Scikit.audiolab dependency to PySoundFile?

[liujimj]

Hello, I just started playing around with this project but found it hard to get Scikit.audiolab working (it looks like it's been inactive since late 2010, doesn't have Python3 support, etc.).

Would you consider migrating the file I/O routines to something more actively maintained, like PySoundfile? I have a working copy of transform_audio.py with modifications that uses it, and I'm happy to submit pull requests for other call sites. Thanks!
