kAudioFormatProperty_MatrixMixMap

A matrix of scaling coefficients for converting audio from one channel map to another in a standard way, if one is known. Otherwise, an error is returned. Set the inSpecifier parameter to an array of two pointers to AudioChannelLayout structures. The first points to the input layout, the second to the output layout. The value is a two dimensional array of Float32 values, where the first dimension (rows) is the input channel and the second dimension (columns) is the output channel.
