Microphone Calibration Files

Microphone calibration files should be in text format, and could have one of a number of file extensions (.txt, .csv, …) The extension is easy to change, but the data format is less so. Here is the start of a calibration file that I received from Earthworks:

"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

The first two lines are ignored, and the file will work with just the data values. You can also add a third column that contains phase information as well.
