Audio analyzer with Spectrum, Wave, power and Sonogram.
Determine the sample rate, and hence frequency range - 8,000(4kHz) 16,000(8kHz) 22,050(11kHz) 44,100(22kHz)
Set the input block size - 128 to 1024 samples
Set spectrum windowing (to eliminate spurious frequencies)
Improve performance by processin only a portion of the input
Determine amount of smoothing in the histogram
Chose which instruments are display
