1 have a known sound
record something which you know, and save this in both numpy and audio 
format.

2 Ensure the test fixture is actually 'the sound' by outputting (both) 
to speakers.

3 Build a test which accepts any input sound, and compares that against 
the above (both formats) - if the input-sound is the same*, the test 
passes, else...

* I fear that defining this, is a bit more involved than describing it!
