Detailed Description

Main header for the Covariance Domain Framework module (SAF_CDF4SAP_MODULE)

Covariance Domain Framework for Spatial Audio Processing (CDF4SAP). This is a direct C port of the MATLAB function given in [1], which was originally written by Juha Vilkamo. It is explained in further detail in [1,2].
