void(* LPCContext::lpc_apply_welch_window) (const int32_t *data, ptrdiff_t 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

Definition at line 68 of file lpc.h.

void(* LPCContext::lpc_compute_autocorr) (const double *data, ptrdiff_t 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 lagsizeof(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.
