vDSP_biquadm_CopyStateD
Copies the filter state from one dopuble-precision multichannel biquad IIR filter object to another.
Declaration
void vDSP_biquadm_CopyStateD(vDSP_biquadm_SetupD __dest, const struct vDSP_biquadm_SetupStructD *__src);Parameters
- __dest:
The
vDSP_biquadm_SetupDobject whose state you wish to overwrite. - __src:
The
vDSP_biquadm_SetupStructDobject 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_CreateSetupD. Both objects must have the same number of channels and sections.
