Perform Calibrated Spectral Analysis. Use mic_calib to calculate the calibration factor. Multiply the time records by the calibration factor and process the time records with pressure _spectra. pressure_spectra is the main program and allows the user to input the bin_size, number of averages, sampling frequency, and has options for maximizing the number of averages and forcing the bin_size to a factor of 2.
