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 fil‐
tering.
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.
