§ celp_lp_synthesis_filterf
| void(* CELPFContext::celp_lp_synthesis_filterf) (float *out, const float *filter_coeffs, const float *in, int buffer_length, int filter_length) |
LP synthesis filter.
- Parameters
-
| [out] | out | pointer to output buffer
- the array out[-filter_length, -1] must contain the previous result of this filter
|
| filter_coeffs | filter coefficients. |
| in | input signal |
| buffer_length | amount of data to process |
| filter_length | filter length (10 for 10th order LP filter). Must be greater than 4 and even. |
- Note
- Output buffer must contain filter_length samples of past speech data before pointer.
Routine applies 1/A(z) filter to given speech data.
§ celp_lp_zero_synthesis_filterf
| void(* CELPFContext::celp_lp_zero_synthesis_filterf) (float *out, const float *filter_coeffs, const float *in, int buffer_length, int filter_length) |
LP zero synthesis filter.
- Parameters
-
| [out] | out | pointer to output buffer |
| filter_coeffs | filter coefficients. |
| in | input signal
- the array in[-filter_length, -1] must contain the previous input of this filter
|
| buffer_length | amount of data to process (should be a multiple of eight) |
| filter_length | filter length (10 for 10th order LP filter; should be a multiple of two) |
- Note
- Output buffer must contain filter_length samples of past speech data before pointer.
Routine applies A(z) filter to given speech data.
