vDSP_biquad_SetCoefficientsDouble

Declaration

extern void vDSP_biquad_SetCoefficientsDouble(vDSP_biquad_Setup __setup, const double *__coeffs, vDSP_Length __start_sec, vDSP_Length __nsec);

Parameters

• __setup:

  The biquadratic filter setup object that the function updates.

• __coeffs:

  A pointer to the new coefficients.

• __start_sec:

  The first section that the function updates.

• __nsec:

  The number of sections that the function updates.

Discussion

Use this function to update sections of coefficient values of a biquad setup structure. This function doesn’t allocate new memory. The range that you specify using __start_sec and __nsec must be within the number of sections that you define in the create setup function.
