5.3.2 Frequency Response

>Frequency Response or click the arrow to the right of the Freq. Resp.
button.
The top line displays the current Sampling Rate, which is set in the Audio I/O tab.
Window: Hanning, Hamming, Blackman, Blackman-Harris, Max Flat Top, Parzen,
Welch. Set to Hanning unless you have a well informed reason to change it.
FFT: FPPO, 32k, 16k, 8k, 4k, 2k, 1k, 512, 256, 128
Graph Line Thickness: Select 1-5 from the menu to set the thickness of the graph
lines. Note that this setting applies to the narrowband RTA display as well as Frequency
Response Traces.
Show Coherence Trace: Check this box to show the Coherence trace in the Magnitude
display.
Swap Transfer Inputs: Swaps the left and right inputs
Mag Threshold: Sets the magnitude threshold of the Magnitude display. Magnitude
Thresholding is another way to limit undesirable data from Frequency Response mea-
surements by setting a threshold for the reference signal level, below which incoming
measurement signal data is rejected on a frequency-by-frequency basis. Smaart 6 looks
at every frequency data point in the reference signal and if it falls below the threshold,
the corresponding point in the Magnitude trace is not plotted when the display updates.
