Functions

 REMATRIX_FUNC_SIG (stereo_to_mono_packed)
 REMATRIX_FUNC_SIG (stereo_downmix_packed)
 REMATRIX_FUNC_SIG (mono_to_stereo_packed)
 REMATRIX_FUNC_SIG (mono_downmix_packed)
 This is for when we have more than 2 input channels, need to downmix to mono and do not have a conversion formula available.

REMATRIX_FUNC_SIG ( mono_downmix_packed   ) 

This is for when we have more than 2 input channels, need to downmix to mono and do not have a conversion formula available.

We just use first two input channels - left and right. This is a placeholder until more conversion functions are written.
