File Information 
Description 
This series of Mfiles generates normalized Aweigthing, Cweighting, octave and onethirdoctave digital filters. These type of filters are commonly used in acoustical measurements, for example, in noise control. The implementation is based on the IEC standard for A and Cweighting filters and on the ANSI and IEC standards for octave and onethirdoctave filters. A complete onethirdoctave analyzer with graphical output is also provided.
