NAME
mlib_SignalUpSampleFIRInit_F32S_F32S - upsampling with filtering
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalUpSampleFIRInit_F32S_F32S(void **state,
const mlib_f32 *flt, mlib_s32 tap, mlib_s32 factor,
mlib_s32 phase);
DESCRIPTION
The mlib_SignalUpSampleFIRInit_F32S_F32S() function allocates memory for the internal state structure and converts the parameters into an internal representation for upsampling immediately followed by FIR filtering.
PARAMETERS
The function takes the following arguments:
state
-
Internal state structure.
flt
-
Filter coefficientarray in two-channel stereo format. src[2*i] contains channel 0, and src[2*i+1] contains channel 1 array.
tap
-
Taps of the filter.
factor
-
Factor by which to upsample.
phase
-
Parameter that determines the relative position of an input value, within the output signal.
0 ≤ phase < factor.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
