Calibrated Spectral Analysis description

This is a simple Fourier Spectral Analysis of sound pressure time record with a calibration

The script uses mic_calilb to calculate the calibration factor.

It multiplies 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.

Requirements:

· MATLAB 7.4 or higher
· MATLAB's Signal Processing Toolbox
