All graphs in the frequency domain category share the following settings.
Normalizing a frequency domain graph will locate its maximum data point and set that as the 0dBFS reference for plotting.
The log frequency scale is used by default when displaying the Frequency axis, since that is closest to how our ears perceive audio frequencies. When viewing low frequencies and/or to help identify harmonics (i.e. scalar multiples of frequencies), try disabling this setting.
You can set smoothing amounts ranging from None to 1/3 Octave. This smoothing is applied regardless of the Log Frequency Scale setting.
With lower-frequency data, the FFT does not provide nearly as much data as in the high frequency range, so be aware that you are discarding valuable data from the FFT calculations in lower frequencies when this is enabled.
When selecting multiple Measurement Records, FuzzMeasure defaults to the Compare mode to show them together on the same graph. FuzzMeasure also offers the following Comparison settings:
Note: In all cases, the order of the records in the Measurements list is used as the sort ordering when performing the above operations. If you wish to change the order of operations, use drag & drop to reorder the measurements in the list. |
Note: The above operations are calculated on the data before converting to decibel units, unlike previous versions of FuzzMeasure. Operations that are similar to the old methods will be offered again in a future release. |
