The following sounds have a too high samplerate, they have to be downsampled. This is possible with for example Audacity.

*** Invalid sample rate (8000) for sound 'fnaf2\buzzlight.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\metalrun.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\metalwalk1.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\metalwalk2.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\metalwalk3.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\ventwalk1.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\walk1.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\walk2.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\walk3.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\walk4.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\walk5.wav'.
*** Invalid sample rate (8000) for sound 'fnaf2\windup2.wav'.

This should be fixed very easily.
