Weighting functions

Weighting functions generates the spectra for common weighting functions. The functions available are A-Filter, C-Filter, EIA426B, IEC268-1 progr., IEC268-16 male, IEC268-16 female and pink (-3dB/oct.).

Additionally, attenuation of sound propagation in air can be calculated based on the parameters distance, air pressure, temperature and relative humidity (using ISO 9613-1).
