Audio Weighting Filters

In R2010a, you can design several types of audio weighting filters. Audio weighting filters model the frequency and level-dependent perceptual weights of the human auditory system. The filter specification object fdesign.audioweighting provides support for A, C, C-message, ITU-T 0.41, and ITU-R 468-4 weighting filters.

Functions, Objects, Object Methods, and Object Properties Being Removed
