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.

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.
