Does the audio sound proper when playing back, or does it sound especially fast (like a chipmunk) or slow (like the dying HAL9000 in 2001)?
Just trying to get a handle on whether the 96 kHz sample rate is a function of a mis-written WAV header (in which case you don't need to resample) or if it was actually and truly recorded at 96 kHz (in which case you do need to resample).
