mlib_status mlib_SignalLPCAutoCorrelInit_F32(void *state, mlib_s32 length, mlib_s32 order);
Each function initializes the internal state structure for autocorrelation method of linear predictive coding (LPC).
The init function performs internal state structure allocation and global initialization. Per LPC function call initialization is done in LPC function, so the same internal state structure can be reused for multiple LPC function calls.
Each function takes the following arguments:
state
length
order
Each function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
