View type
View type controls the way the spectrum is displayed. By default a smooth curve is presented. This view provides the best
resolution and detail, but other modes (1/3 octave, 1 octave) may be easier to read.
Opacity
Opacity controls opacity of all analyzer graphs.
Resolution
Resolution defines vertical range on the display. Human auditory system has a resolution of about 90dB and the relevant
range is usually less than 60dB. However you may want to use a higher resolution to check for technical problems -
aliasing, distortion etc.
Analysis
Channel mode
Channel mode defines which channels should be analyzed. By default all channels are merged into a mono sum, which is
then analyzed. However you may want to analyze separate channels or display left and right channel at once.
Decay
Decay controls the speed the magnitudes return to the minimum value, the silence. It is an alternative to averaging, which
affects both the speed the frequencies gain and lose their magnitudes. W ith 0% the magnitude goes to minimum
immediately. With 100% it stays the same forever, so it makes it basically computes the maximum.
Super-resolution mode
Super-resolution mode activates a special processing algorithm, which provides high resolution even in low frequency
spectrum. Using standard FFT algorithms you can increase FFT size to get better bass resolution, but this also slows down
the response. Super-resolution mode performs complicated processing, which keeps quick response in high frequencies as
they are naturally quicker, but also highly enhances bass spectrum resolution. It requires additional CPU power.
Enable when hidden
Enable when hidden causes the engine to process even when GUI is hidden. Otherwise the sonogram is stopped,
therefore will not be immediately available when the GUI is shown again.
Analysis panel
Analysis panel contains more advanced settings controlling the scientific parameters of the audio analysis.
