Functions

	Name	Description
TUniquePtr < ...	CreateBaseFormatConverter ( const FInputFormat& InInputFormat, const FOutputFormat& InOutputForma..., TArrayView < const FChannelMixEntry ..., int32 InNumFramesPerCall )	Create a FBaseChannelFormatConverter
float	GetTargetMixGain ( int32 InInputChannelIndex, int32 InOutputChannelIndex )	Returns the scalar gain used to mix the input channel index into the output channel index.
float	GetTargetOutputGain()	Returns the scalar gain applied to the output audio.
void	SetMixGain ( const FChannelMixEntry & InEntry, bool bFadeToGain )	Sets the gain scalar to apply to a specific input/output channel pair.
void	SetMixGain ( int32 InInputChannelIndex, int32 InOutputChannelIndex, float InGain, bool bFadeToGain )	Sets the gain scalar to apply to a specific input/output channel pair.
void	SetOutputGain ( float InOutputGain, bool bFadeToGain )	Sets the output gain scalar to apply to all output audio.
