Function

vDSP_biquadm_CopyState

Copies the filter state from one single-precision multichannel biquad IIR filter object to another.

Declaration

void vDSP_biquadm_CopyState(vDSP_biquadm_Setup __dest, const struct vDSP_biquadm_SetupStruct *__src);

Parameters

__dest

The vDSP_biquadm_Setup object whose state you wish to overwrite.

__src

The vDSP_biquadm_SetupStruct object whose state you wish to copy.

Discussion

Both src and dest objects must be valid single-precision multichannel biquad setup objects created by previous calls to vDSP_biquadm_CreateSetup, and both objects must have the same number of channels and sections.
