IIRChannel

Constants that specify which channels a stereo biquadratic filter operates.

Declaration

typedef int IIRChannel;

Discussion

Pass an IIRChannel constant to vDSP_biquad2_CreateSetup to specify which channels the function applies filtering to.

vDSP_IIRStereo

The filter operates over both channels.

vDSP_IIRMonoLeft

The filter operates on left-channel mono data and applies pass-through coefficients to the right channel.

vDSP_IIRMonoRight

The filter operates on right-channel mono data and applies pass-through coefficients to the left channel.
