Do you apply a window before analysis?

> I'm analyzing some audio using the CASpectralProcessor class from the public utility. I'm finding that the class sometimes produces different spectra for exactly the same input. I verified the input is identical (no bug there) but the spectra processing callback receives a spectra with different values. I'm using a window of 512 and a hop size of 128. It doesn't happen always, seems like every time I init the class I can either get the same results as last time it was created, or different results.
