Importing using Calibration Files

FuzzMeasure can recognize calibration files as long as they are in a text format that is common to most microphone manufacturers

Import a Calibration File

FuzzMeasure supports calibration files with .txt, .csv, or .cal file extensions, with comma-separated columns of data. Frequency and Magnitude (dB) rows are expected to appear in the file, with an optional third column for Phase.

Below is a sample of the kind of data FuzzMeasure expects to encounter. Note that the first few rows start their comments with a quotation character.

"Transfer Function Mag - dB volts/volts (0.10 oct)(eq)(eq:aux)"
      "Hz"      "Data"
    781.25,  0.7222968
  820.3125,  0.7226313
   859.375,  0.7241868
Note: FuzzMeasure expects the calibration file to represent the microphone's frequency response and not its correction curve, which is the standard among the manufacturers we've dealt with thus far. That is, FuzzMeasure will subtract the quantities in this file from its Frequency Response graphs to compensate for the microphone's frequency response.
