§ lpc_apply_welch_window
| void(* LPCContext::lpc_apply_welch_window) (const int32_t *data, int len, double *w_data) |
Apply a Welch window to an array of input samples.
The output samples have the same scale as the input, but are in double sample format.
- Parameters
-
| data | input samples |
| len | number of input samples |
| w_data | output samples |
§ lpc_compute_autocorr
| void(* LPCContext::lpc_compute_autocorr) (const double *data, int len, int lag, double *autoc) |
Perform autocorrelation on input samples with delay of 0 to lag.
- Parameters
-
| data | input samples. constraints: no alignment needed, but must have at least lag*sizeof(double) valid bytes preceding it, and size must be at least (len+1)*sizeof(double) if data is 16-byte aligned or (len+2)*sizeof(double) if data is unaligned. |
| len | number of input samples to process |
| lag | maximum delay to calculate |
| autoc | output autocorrelation coefficients. constraints: array size must be at least lag+1. |
