This adds a sliding window buffer approach to the audio sample data as well as force the user to set the sampling rate of the input data. This was needed to stabilize fft output to a usable degree. Also the fft output is now in db, which makes it a lot better to look at. Signed-off-by: tyrolyean <tyrolyean@tyrolyean.net>
