§ acelp_apply_order_2_transfer_function
| void(* ACELPFContext::acelp_apply_order_2_transfer_function) (float *out, const float *in, const float zero_coeffs[2], const float pole_coeffs[2], float gain, float mem[2], int n) |
Apply an order 2 rational transfer function in-place.
- Parameters
-
| out | output buffer for filtered speech samples |
| in | input buffer containing speech data (may be the same as out) |
| zero_coeffs | z^-1 and z^-2 coefficients of the numerator |
| pole_coeffs | z^-1 and z^-2 coefficients of the denominator |
| gain | scale factor for final output |
| mem | intermediate values used by filter (should be 0 initially) |
| n | number of samples (should be a multiple of eight) |
