This series of M-files generates normalized A-weigthing, C-weighting, octave and one-third-octave 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 C-weighting filters and on the ANSI and IEC standards for octave and one-third-octave filters. A complete one-third-octave analyzer with graphical output is also provided.
