DESCRIPTION
Each of these functions allocates memory for the internal state struc‐
ture and converts the parameters into an internal representation for
rational sample rate conversion with FIR filtering between upsampling
and downsampling.
PARAMETERS
Each of the functions takes the following arguments:
state Internal state structure.
flt Filter coefficient array, two-channel interleaved in the
cases of stereo.
tap Taps of the filter.
ufactor Factor by which to upsample.
uphase Phase in upsampling. 0 ≤ uphase < ufactor.
dfactor Factor by which to downsample.
dphase Phase in downsampling. 0 ≤ dphase < dfactor.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
