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